    Don't break down when it's cold outside.

    Cerium is the most abundant rare earth metal, and it decomposes slowly in cold water and rapidly in hot water. The Arc'teryx Men's Cerium LT Hooded Down Jacket is not quite as prevalent as its namesake, but it does slow your decomposition in cold weather. The combination of 850-fill European goose down and strategically placed Coreloft insulation keeps you warm whether you wear the Cerium alone or under a hardshell when you're confronted with a winter tempest most storm chasers avoid.

    Big numbers are fun when it comes to betting odds and down insulation. A higher fill-power down, like the 850-fill used in the Cerium, refers to how much space a single ounce of down occupies. The more space taken up by the down means more air is trapped between the fibers. Trapped air creates a barrier between warm air from your body and cold air in the environment, so you stay warm when it's cold outside. Taking this logic one step further, if one ounce of a certain down takes up more space than a different type of down, it stands to reason you'll need less of the 'bigger' down to keep you warm, thus reducing the weight of your jacket. In essence, this jacket's high down fill makes it both light and warm.

    Since down doesn't maintain its warmth when it gets wet, the folks at Arc'teryx placed synthetic insulation in the spots that are most likely to get a bit damp. Still, while Coreloft insulation does resist moisture better than down, and an ominous drizzle won't leave you a cold, soaking mess, it's best to pair this jacket with a waterproof shell if you know stormy weather is coming. This superlight hooded jacket comes with its own stuff sack so you can easily bring it along and so your pack stays organized. The same 850-fill down fills the low-profile StormHood so your melon stays warm. (Mom was right—if you keep your head covered, you'll stay warmer.) Two zippered hand pockets hold your keys and phone, trail map and candy, or your partner's ID and lip balm.

    Great warmth, bad durability

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: L
    • Height: 5'10"
    • Weight: 200lbs

    I got the jacket, and fell in love with the warmth and lightness of it. However the quality left much to be desired, as down feathers would poke out of the fabric as it slowly lost down.

    Second, after getting caught in a rainstorm while wearing it, the entire jacket started falling apart, fabric just disintegrated and the jacket became unusable. Do not have this jacket on if it starts raining! Arcteryx was of no help in there warranty department so far. I was only offered a discount on a new purchase.

    In my opinion this should not happen if you get caught in the rain!!!.

    Sadly, I have lost a good amount of faith in Arcteryx quality with this piece.

    Go to belay jacket

    • Size Bought: Medium
    • Height: 5'10"
    • Weight: 170lbs

    Few things I look forward to more than throwing my Cerium on at the top of a skin track on a cold dawn patrol morning. It's super packable and super warm, I don't think there's much more you can ask for from a puffy.

    Top Notch Quality

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: medium
    • Height: 5'8"
    • Weight: 165lbs

    I bought this from a local gear trade page on Facebook for $125. I feel like I basically stole it. This jacket is very well put together. It replaced my old TNF Summit Series 900 fill coat and its better in every way except for the inability to cinch up the bottom around the waist. (There is no drawcord) Definitely still a very versatile jacket and an indispensable addition to my layering system for backpacking. Medium was perfect for me at 5'8 w/muscular build.

    Great jacket, service grief

      I like this jacket, it replaced my 5 year old Down Sweater. Very light and extremely warm. The zipper kept switching sides on the unzip or would pull off the jacket entirely. I bought this in November '16. The zipper is now lost, so this jacket is comprimised. I have to ship this Cerium LT to WA so it can be transferred to Arc'teryx headquarters to be fixed, and it could take up to 20 days. I'll be going through January and into Feburary without this jacket. Not happy with Arc'teryx service.

      Great jacket!

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Small
      • Height: 5'7"
      • Weight: 135lbs

      This jacket is light and warm. I bought this to replace my old Western Mountaineering Hooded Flash Jacket. They have almost the same amount of down but my old jacket is a little warmer because it is constructed to be more puffy. This jacket is definitely more stylish and form-fitting but the arm-pit section could potentially be a little tight for some. This plus a fleece jacket and a 260 weight icebreaker shirt is enough to keep me warm for the whole winter in New York area both in the city and out in the woods. However, you probably need a rain jacket or soft-shell if it rains. It can hold up in light rain though.

      Love this jacket

      • Familiarity: I've used it several times
      • Fit: True to size
      • Size Bought: Medium
      • Height: 5'7"
      • Weight: 165lbs

      I bought this for my husband and here what he has to say about it:

      I am 5'7" 165 and the medium fits perfect. It sits just below the waistline so if you want a longer fit and have longer arms, you may want to size up. This jacket is extremely warm and light. I hiked in 18 degree weather with just a long sleeve base layer and was still a little too warm. Quality is second to none.

      Double Down

      • Familiarity: I've used it several times
      • Fit: Runs small
      • Size Bought: first a Large now an XL
      • Height: 5'8"
      • Weight: 185lbs

      I love this jacket. The warmth is just insane also has a huge range of motion. I am 5'8 and have a Pennsylvania wrestlers build and I wear Large in everything. Every Arc'teryx jacket, shirt, and layer I own is a size large. I bought this jacket in a large and I looked like a hotdog and only had a T-shirt underneath. In really cold weather I can wear a flannel- Mtn. Hardwear Ghost Whisperer down jacket under my Atom LT under my Alpha SV shell and be completely fine but this coat for me runs small.

      If you are narrow you should be fine but if you are stout order a size up and it will fit like your normal size coat.

      Also, if you are tall you might be wearing a belly shirt. Seems like the coat was intended for a shorter torso. But, I am not tall so hopefully it works for you.

      Just size up

      Perfect down jacket? yes

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: XL
      • Height: 6'1"
      • Weight: 200lbs

      I normally wear an XL jacket or shirt and this arcteryx jacket was no exception.

      Jacket has a great athletic style fit to it. Makes even us "soft shaped" individuals look athletic! Does not make you look like a marshmallow. The high loft down means the jacket is quite thin and still warm. Length and sleeves are perfect for me.

      I brought this on a 4 day backpack trip to isle royale and it was just what the doctor ordered. It packs down to about half the size of a Nalgene during the day (amazing). At night you can unpack it and be comfortable well below freezing. I wear it in winter with my arcteryx beta at hardshell when the weather really goes south.

      The quality is outstanding. The coat feels great. The zipper feels a little small to be durable, but they have never given me any trouble. If they do, I have a lifetime warranty. The coreloft around the chin, wrists, and pits is brilliant. Depending on the activity you may break a sweat in this; you don't want that sweat to destroy your insulating capabilities. For me I sweat and vent from the wrists and the coreloft holds up great there.

      I can not personally tell you if a $400 jacket is right for you. I got mine cheaper from steep and cheap. I was hesitant at first but have never looked back since I got my hands on the jacket.

      Finally thoughts:
      Do not bring this on backpacking trip hoping it will double as your pillow. 850 fill power down makes for a terrible pillow.

      Perfect for backpacking

      • Familiarity: I've used it several times
      • Fit: True to size

      This jacket is warm light and simple and that's all I want for an ultralight backpacking piece. The face fabric seems to cut the wind pretty well and the DWR and strategically placed synthetic on the shoulders and cuffs made me more comfortable wearing in light snow or a very light drizzle.

      Im 6 foot 170 lbs and the M fit nice and close. I was able to fit a base layer and a fleece underneath but much more would have been restricting. I wore it in some pretty decent snowy wind and did not notice any heat loss from the waist as other reviewers have mentioned.

      Great product, nearly perfect

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Small
      • Height: 6'0"
      • Weight: 150lbs

      Very warm, very weather resistant for weight and great fit. Even with the great fit and hood, there is still a way for cold air to seep in. The waist!! There is no drawcord for the waist! This jacket would be perfect if there was. Cold air gets in from the bottom... This can minimized by filling out the layers beneath, to create a tighter fit (obviously not too tight).

      Everything i was expecting

      • Familiarity: I've put it through the wringer

      I'm not a big skier and when I made the purchase over the winter I was itching to add this super-packable piece of gear to my backpacking kit. Could. Not. Be. Happier. When you're tramping around above 9000 feet it gets pretty cold when the sun goes down, even in July. Luckily this little core keeper will vastly reduce the additional layers you typically feel like adding to your pack. First night dipped under 30 and I did need to couple it with my sleeping bag, but otherwise I was able to sleep soundly in a hammock. Add a light rain jacket on top, though. It is down, after all. Glorious, featherlite, fever-inducing down...

      Everything i was expecting

      I love this jacket so much I bought 2!

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I have the light blue and dark blue. Great warmth and style. and the hoodie doesn't drown me.

      From town to summit

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Large
      • Height: 5'11"
      • Weight: 190lbs

      First off, the navy/maroon color is great if you care about that sort of thing. It looks as good with a pair of jeans as it does with a soft shell.

      Second, oh my god warm! I was stuck in a storm high on Aconcagua for 3 days with wind chills far blow zero. I threw my hard shell over this puffy and could not believe that I never got cold when outside my tent. When I was moving on the non-storm days I wore my hard shell and would throw this over the top on breaks to keep in the warmth. The pockets a perfect for warming up the hands and the included stuff sack keeps this thing to minimal size when packed away.

      Third, as you would expect from this brand, it held up well to life on the mountain. No snags and when professionally cleaned it looked as good as the day I bought it. I am 5'11", 190 lbs and the large fits great.

      Versatile ultralight warmth

      • Familiarity: I've put it through the wringer
      • Fit: True to size
      • Size Bought: Xl
      • Height: 5'11"
      • Weight: 185lbs

      Got this jacket to be used as a packable layer for winter camping, hiking, and skiing in New England. I now use it all four seasons either under a hard shell or on its own. Be careful if you wear it as an outer layer because the shell is delicate.

      I went with xl so I could have layers underneath and not feel too restricted, on its own a large would fit better, but for my use the xl was a better choice.

      Amazing how small and light this jacket is. On its own with a base layer it was comfortable to around 30, but with a hard shell over and fleece underneath I was comfortable to around zero.

      Great to throw on during breaks, the summit, or at night , a bit warm for high output movement unless it's real cold.

      Have yet to get it too wet, but definitely a good move having synthetic fill on shoulders and cuffs. I understand Arcteryx going for ultralight with this jacket but I still wish they had included a draw string to keep the bottom tight, definitely loses heat out the bottom especially on windy days but I'm sure if I had gotten the large it would be less of a problem.

      Lightweight and toasty

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size
      • Size Bought: XL
      • Height: 5'10"
      • Weight: 170lbs

      Got this for my husband to wear under his waterproof shell. Loves how warm the goose down keeps him and now wears it almost daily when he's out in the early morning freeze. Low pro hood is nice, overall fantastic jacket.

      Great Winter Fav

      • Familiarity: I gave it as a gift but have feedback to share
      • Fit: True to size

      This jacket is ultra light and does provide great warmth thanks to its built-in insulation. It also comes in a small draw-string bag.

      which size i can choose for Arc'teryx Cerium LT Hooded Down Jacket - Men's , my weight :143.3lb and height: 67 in

      Hey Elina, As it has a more trim fit, i'd recommend going with a medium for it to be most comfortably fitting for you! If you have any other questions or anything I can do for you, feel free to reach me at cojohnson@backcountry.com or my direct line 801.204.4547! Cheers, Connor

      Does anyone know which is warmer between this jacket and the Patagonia Down Sweater Hoody? I realize warmth is somewhat subjective, but I'm just curious if there is any measurable difference between the two aside from weight.

      The reviewers at outdoor gear lab said that the Patagonia down sweater is slightly warmer, and they're pretty detailed in their reviews. I'd check em out to see which one is best for you. http://www.outdoorgearlab.com/Down-Jacket-Reviews/Patagonia-Down-Sweater-Hoody

      Cerium LT is 850 down fill at 275g total, and Down Hoody is 800 down fill at 428g total, 56% heavier. Despite a slightly less fill ratio, the Patagonia will have significantly more fill insulation and will keep you a notch warmer. These type of jackets don't breath well unless they have some sort of hybrid breathable panels, so I always say get the warmest you can comfortably carry, which would be the Patagonia. Only reason to get the Arc'teryx would be if you'll be carrying it frequently in a pack and need to absolutely pinch grams.

      Which by the way, Backcountry.com it's time you list Grams on all your products...the entire world and most manufactures use only Grams, yet you still don't have it...

      I'm not sure Snorske has their info correct........this jacket claims total overall weight of 9.7 oz and stats 3.35oz of down fill weight. 9.7 x28 grams =271.6 grams so Snorske claim of 275 grams is not the weight of the down or a reflection of the warmth. So according to my research and numbers thats but 93.8 grams of actual down fill. In comparison TNF Super Diez is a 900 fill down with 130 grams of actual down fill.

      Which jacket is warmer? The Arc'teryx Cerium LT or the Arc'teryx Thorium AR?


      For the most part the jackets will be fairly similar but looking into the details, here is a break down of the finer points:

      Thorium AR (down): 750

      Cerium LT (down): 850

      Thorium AR (fill weight): 3.5oz

      Cerium LT (fill weight): 3.35oz

      Thorium AR (Synthetic insulation): 80/140grams

      Cerium LT (Synthetic insulation): 80/100grams

      So after looking at the breakdown of the insulationthe Thorium will have more insulation in it but in the case of the down it'll be slightly lower quality (but really 850 to 750 isn't a huge difference).

      I'd look at how you want the jacket to fit since the Thorium AR is an "athletic" fit and the Cerium LT is going to be a snugger fit due to it being a "trim" fit.

      Shoot me an email anytime you have questions!

      Expert Gearhead



      Thorium has more of a square cut and the Cerium has more of a trim fit. The Arc store rep had the same basic take as Jared (gear Expert) above did that they are more or less the same warmth, so it's more or less the cut you prefer.

      I'm 185 lbs 5'11 and like a snug coat and the medium in the thorium was good for me, but for the Cerium i'm going to go with the large. hope that helps

      What is the best size for me - I've heard the Cerium LT is a trim fit. This would be worn as a base layer. I'm 5'8", 140lbs, 37-38" chest with 31" waist and hips. I have an Arcteryx Alpha SV size small which has plenty of room for layering up under it but as I understand it the Cerium LT is a whole other fit altogether. Thanks

      Honestly i think you should look at the small. I am similar size (a bit larger) and went with the medium initially and found that the jacket just wasn't that warm. Wind would blow right up the back. With the small, i didn't lose any freedom of movement, but gained a lot of warmth as the hem of the jacket worked the way it was designed.

      I'm 5'10 and my current weight is 180 I want to layer up under this jacket for NYC winters what's your best recommendation for a comfortable fit medium or large?

      Since it has a trim fit I would get the large to make it comfortable. You could probably fit into a medium but, it might be snug especially when you layer underneath it. What is your chest measurement? That is a really good indicator of how the jacket will fit.

      If you have anymore questions feel free to send me an email or call!

      Bill Porreca



      Michael -

      Just tried on the Medium and the Large at the store. I'm basically the same dimensions as you and the Large fit perfectly over an undershirt and a regular fit button up shirt. The medium was form fitting, but a bit tight in the sleeves.

      I also tried on the Thorium AR Down which is a more of a regular fit/square cut and the Medium version of that was more roomy than the Large in the Cerium.

      Are these made in China? I just got one on ebay for a deal and it says "Made in China." However, a search of the web shows that apparently a lot of Arcteryx goods are made in China. I just want to confirm as I'm returning the ebay purchase and planning to re-buy the jacket here, assuming it's not made in China. (And assuming the size is right. Everything I read about these jackets said they run small so I bought a large, but it's huge on me.)

      Best Answer

      It is made in China, but that doesn't mean anything. As I know this jacket definitely has counterfeit in color nighthawk and black. I suggest you to purchase from authenticated sellers.

      Hello, I'm torn between getting this jacket and L.L. Bean's Ultralight 850 Down Hooded Jacket. Does anyone have experience with both so that they can compare them together?

      Best Answer

      Haven't tried this hoodie, but I can tell you that the Bean hoodie is a little gappy in the middle, and the hood - although very good - isn't adjustable. Also - when last I checked, it wasn't available until JUNE!

      I just received my LL Bean Ultralight and love it (was told it was back ordered to June 1). Very light, has Pertex shell, inside skins pocket and zip pocket that the whole jacket packs into and 3 outside zippered pockets. Got it on sale for about $170. I am 6'1, 195 and fit nicely in a Medium Tall. Nice fit. We'll see how it holds up but has a lot of features for the $.

      Which is warmer, Cerium LT or Western Mountaineering Flash XR? Also, which is smaller when compressed?

      I will be wearing one of these under a softshell jacket during multi-day alpine climbing in winter Alps.

      I'll ask what's gonna be warmer n last longer this or the Patagonia down sweater

      Patagonia Down sweater will be warmer and last longer but, it is not as performance oriented as the Cerium LT. The Cerium LT is meant for light, fast moving through the mountains where the Down Sweater has more of an all around purpose.

      Hey everyone--quick question.

      I have a hard shell (barely insulated) and a solid fleece. I was hoping to get a light-weight down jacket to layer with, or wear alone conditions permitting. I hike (nothing too intense) 1-2x/month when I can get free. I'm looking to buy a down jacket that I can use to stay warm up in Boston, both when I'm just getting around and also when I get to hike.

      My question is this: is there a reason to get, or not get, this jacket with a hood? I don't really imagine too many times where I'd use the hood, but I'm not really sure. The price difference isn't a big deal if there's something I'm missing. Ideally, I'd like to wear this with a shirt or light baselayer to get around, so maybe having a hood around helps in case it get's wet, but then, I would want a shell regardless for the down, no?

      Best Answer

      Yes if it is raining you will want a shell. It's a personal preference but I tend to find most people like hoodless for a mid layer piece and the hood when wearing as a stand alone. However, depending on your shell a hood will not work on certain types jackets necks. I personally only have hooded pieces but all of my shells have storm hoods.

      Im 5'6 and 160lb with a chest size of 39"....

      Im 5'6 and 160lb with a chest size of 39". I'm guessing the medium would suit, but I'm considering the small due to not wanting excessive length in the arms. Any recommendations?

      Best Answer

      The Arc'teryx Cerium LT is based on a trim fit block. I would recommend the medium as I think a small would be too tight through the chest area. The difference in sleeve length is only 1", so you should be GTG.

      I have an Atom SV but I am after something a little warmer for an insulation layer.

      Will the Thorium be warmer than the Atom SV?

      Anyone using this with a pack? I know its...

      Anyone using this with a pack? I know its designed as a mid layer, but anyone have any wierdeness where the straps of the pack rub? just curious

      Best Answer


      I am assuming by "wierdness" you are referring to fast wear in the shoulder area. I typically wear my Cerium as an outer layer rather than a midlayer, and often with a decent sized pack. While the Cerium's fabric is necessarily light weight I have been impressed with out how sturdy it is. No signs of wear to the shoulders or anywhere else for that matter.

      If someone is concerned about durability I would probably favor choosing the Thorium which has a 40D face farbic compared to 20D in the Cerium. The increased weight is not too substantial from Cerium to Thorium. But again, I have not seen any issues with durability in the Cerium anyway.

      this jacket is so light i find it hard to...

      this jacket is so light i find it hard to believe it will keep me warm so let see how it works: it's about 20 outside right now with a very slight windchill to 17. Having gone out for a tester walk around the block, in just a Tee, i can feel some air get in from the cuffs since it's only elastic. i can also say this jacket lets the NorthEast winter cut right through. If i had a warmer base layer, maybe it'd be OK.

      I cannot seem to find something that works - everything seems to be Light Weight. I tried the Marmot Guide Hoody but didn't find it warm either. What's a good jacket between this ArcTeryx & the LLBean Ascent with Windstopper?

      Best Answer


      You have a fantastic jacket on your hands there but it is important to recognize its intended purpose and potential limitations. As the LT in the name denotes, this is designed to be a high quality lightweight down jacket. You can wear it as an outer layer during clement conditions, but in harsher wind and snow I would definitely layer it under an outer shell. This jacket does not claim to have any sort of windblocking membrane. If you are looking for a down jacket that can stand alone in the harshest of conditions I would suggest the Arc'teryx Therme Parka.

      Hi PL, I think your best bet is going to be something that has both baffled down and a wind-blocking exterior. The Cerium is quilted, meaning that the horizontal pockets that hold the down are sewn through both sides--a baffled down coat uses what essentially is mosquito netting to suspend the down on the inside and create a jacket without any cold spots. I would recommend something like the Marmot Shadow, which is warm, baffled, windproof, and comfy too. Check it out here:

      i think the shadow is a great recommendation, but i would like to make a different point. unless you already have a great waterproof jacket, you can save money and buy a shell to layer over your down jacket on wet and windy days, and wear alone with the mercury isn't too low. also, it doesn't sound like you'd like any light weight insulated jackets, so look for jackets in the 2 pound and up range to get lots of warmth. the trade off is they'll be bulkier.

      6'0" 165lbs, thin and athletic build. Tried the Patagonia down sweater in medium and felt I needed 30 more lbs on my chest to fill out the empty space. Jacket length and arm length were perfect though....going to return and look for something better fitting.

      Recommend a medium for this jacket?

      The official length from Arc'Teryx simply states "hip length" but I have measure it at 26" and sleeve length at 33". I would add to Tester's answer that I am able to fit a medium and a large very well, and I would also recommend the medium for you.

      Would it be safe to say that a large cerium lt should fit like a medium thorium ar? I am 5"10 175lbs and my shoulders and chest are broad. I tried the beta lt in medium and it was too tight around the back and shoulders... Should I size up in a cerium to be comfortable?

      I don't mean to be redundant, but I think it may help other Backcountry customers interested in the Arc'Teryx down jackets to know that the Cerium LT is built according to Arc's Trim fit while the Thorium AR is built according to Arc's athletic fit which is just slightly more generous. I am close to Scott in size and can affirm that a large should fit you well in the Cerium while a medium would fit you the same in the Thorium.

      I just received my cerium jacket. I'm 6'0" 195 lbs and purchased the large. It fits well EXCEPT I find the armpits to be uncomfortable because of the super athletic fit - it feels like you have a material bunched up under your arm when your harms are hanging down to your side. Has anyone else noticed this? Does it "stretch" or give a little over time to be less noticeable? At the moment, this is a deal breaker given the cost of the jacket - I want it to fit and feel well for $275. Thanks in advance.

      6'2" 200 pounds, I also have a Large. I have noticed the same thing, though I have not personally found it an annoyance. I do not think it will give over time (hasn't on mine). I would offer that the Arc's very athletic cut makes it more difficult for some folks to find a good fit with this jacket, body-type dependent of course.

      Between the Arc'Teryx Cerium LT hoodie and...

      Between the Arc'Teryx Cerium LT hoodie and Feathered Friends Daybreak hoodie, which jacket would be the better choice?

      If you are counting your bucks, the the Feathered friends is quite less expansive.

      However, i believe Arc'Terix is more experienced at making down jackets. The Arc'Terix It's a 850 fill down, The feathered friends is supposed to be 900 fill, however people have been reporting that some of them are actually 850 fill...I don't think it does really matter at this level.

      The Arc'Terix has also a nicer look.

      I would go for the Arc'Terix

      If I'm not mistaken this is actually Arc first down jackets, the Cerium and Thorium. FF has been in business since the 70's making down products, http://featheredfriends.com/about/.

      Just to make sure you have all the info you need LaughingH20.

      hegaveitall is correct; in no way is Arc'teryx more experienced with down garments, the Thorium and Cerium are Arc's first efforts. That being said, both jackets are superb.

      Feathered Friends has a near-impeccable reputation for their quality and warmth. I would like to see exactly where "people are reporting" they use 850 instead in the Daybreak, that sounds like hooey to me.

      The Cerium has 97g of down vs. 89.5 for the Feathered Friends. Given the $75 price difference, the choice is yours.

      Get the Arcteryx.

      Feathered Friends makes great sleeping bags , but in my experience, all of their clothing is cut really strange and runs about 3 sizes small. You might like it if you are a really small person with no torso, but you should probably try one on first.

      You can only tell so much by comparing specifications.

      Both jackets will use top-notch materials.

      The arcteryx piece will be perfectly cut and true to size.

      However, the fit of the Feathered Friends jacket might be more "esoteric" so you should probably try it before you buy it (or just get the arcteryx, which is a sure thing).

      Hope this helps.

      Order both, try them on, return one. Specs talk, but fit can scream...yes? And you wouldn't miss that extra $75 in six months, let alone in however many years the thing lasts.
