    Stay warm when you play in the mountains.

    The Rab Men's Infinity Endurance Down Jacket provides lofty warmth whether you're making an ascent on a snow-capped mountain, belaying your friend on a freezing ledge, or just chilling around a campfire at night. This jacket's Pertex Quantum GL fabric helps keep it super light, and its Pertex Endurance coating makes the Infinity Endurance windproof, breathable, and highly water resistant. Insulated with 210 grams of 850-fill power, hydrophobic European goose down, this jacket is extremely lofty, very warm, and extremely light for the heat it produces.

    The Infinity Endurance has a huge hood that you can adjust to cinch down tight over your head when it's windy, or you can loosen it up to make room for a climbing helmet. It also has a wire brim to give the hood nice and sturdy protection from sunlight and falling debris. This jacket has elasticize cuffs and 2 drawcords at both sides of the hem so you can prevent any unwanted winds from blowing up in it. Rab included a stuff sack for this highly-compressible jacket so you can take it with you anywhere whether you're concerned about space or not.

    For the most extreme conditions

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: XL

    I am a Rab fanatic so when it came time to replace my warm yet bulky EMS down coat I knew what brand I would be going with but was not quite sure on the model.

    I had been comparing the Rab Positron and the Infinity Endurance for quite some time. Last winter I bought my fiance the Positron for the harsh winter conditions in the White Mountains. For a woman who by nature is always cold, the Positron kept her extremely warm in the alpine zone.

    I am the opposite. I am always warm and sweat in the winter while I hike. My down coat usually stays in my pack and only goes on when I am above treeline. I felt the Positron would be a little overkill for me.

    Ultimately, what I needed was an extremely warm coat for harsh winter temperatures that would take my minimal room in my pack. The issue I had with my EMS coat is that it took up nearly half the room in my pack which would result in me having to leave essential gear behind. The Infinity Endurance is quite compressible and allows me to fit in any extra stuff that I may need. I should also mention that it is warmer than the EMS too!

    I gave it a four star rating because I feel that coat sacrificed durability for its light weight. The outer material is extremely thin and I would be very hesitant to wear this while walking in the treeline as I feel that it may tear easily.

    The picture I included is on top of Little Haystack on Franconia Ridge in January. Temperatures are close to -30 degrees with windchill. I only have thermal base layer under this coat and I am extremely comfortable and enjoying the elements.

    I have a muscular build and Rab always fits me weird. I am usually a large in their products but got the XL. It is a tad bit big in the length and waist area but fits my back and arms perfectly.

    All and all this is a very warm coat for alpine use and is lightweight.

    Worth Every Penny

    I am just discovering Rab, and I'm very impressed with this jacket. The fit is absolutely perfect, with no extra bulk anywhere. If your body grew its own jacket, it'd grow a Rab Infinity. Super warm but breathable, water resistant, roomy hood, and a stuff sack included to pack it away. I usually order a men's small and expect it to fit rather loosely. Compared to other brands I have (Patagonia, Mountain Hardwear, Arcteryx), this jacket fits smaller through the torso. It is nicely contoured to my body, with plenty of length in the arms, and full range of motion for activities like climbing... with no pulling, bunching, or belly exposure. Freakin love it!

    great combination of weight and warmth

    • Familiarity: I've used it several times

    • Size Bought: extra large

    I sold a perfectly good mountain hardware hooded phantom and replaced it with this. great fit, enough room for a decent layer underneath. great hood adjustments. lots of high-loft down. not the lightest in its class, but I'll trade weight for the slightly more robust fabric in high-impact areas. unlike RAB's shells, which run small, this is true to size. if you constantly encounter sub-zero temps, this probably isn't warm enough. otherwise, it's very hard to beat. Simple, well-executed, outstanding.

    Very happy with it!

    Was looking for a lighter jacket than the Everest style jacket I've had for the last many years. This fit the bill and is way less heavy that what I've been dealing with. I usually go with Eddie Bauer for my down jackets and Patagonia for synthetic. I was very happy to branch out here. And for what I've tried in this range of weight and fill, this one has been my favorite. Mind you, I haven't tried any Montbell yet, so I can't fully compare across the board.
    Either way, sleeve length is great. I almost wish the cuffs held a tiny bit tighter, but that won't really make a difference for what I'm doing. The hood is super cozy and definitely smaller than my Eddie Bauer Peak XV. Oh, and I like the wire thats in the hood. Helps keep that little brim up and out of my way.
    Great sizing through the chest. Perfect torso length for me.

    This thing is amazingly warm. Too warm at times unless you like hanging out in your perspiration. I used this for a season and found it uncomfortably warm. Even in Alaska. Even in extremely cold conditions. I ended up with a Patagonia Fitz Roy due to the lighter weight and compressibility, but don't get me wrong, if you run cold, definitely get this jacket. Feel free to reach out if you have any questions on fit, sizing, or functionality.


    I hate the HUGE hood!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Small

    I owned the Rab Infinity jacket and LOVED it! I upgraded to this Infinity Endurance jacket and ended up not liking it as much as the older version. This version isn't as puffy (I like super puffy), it has the Pertex material which is loud and crinkly, and the hood is probably the biggest helmet compatible hood I've ever seen on a jacket! It does cinch down pretty well, but the elastic cinch cord that goes around the head is located right on my ears which makes it a little uncomfortable. I'm also not a fan of wires in the brims. Although this one is probably the best I've seen done, I'm still not a fan. I have a small head so the hood was a huge turn off for me.

    On the plus side the bungee that cinches around the face tucks VERY nicely inside the collar so it's neat and out of your face. I was very impressed with the attention to detail and the clever design. I wish every jacket had that feature!

    The jacket is incredibly comfortable, lightweight, warm, compressible, and I LOVE the Ebony colorway!

    Best down jacket ever!

    • Familiarity: I've used it several times

    Ok, the jacket just rocks. Super light. Stellar materials. Great design and fit. I'm 5'9" and usually rock medium and medium rocks. I can add even another synthetic under it if I need too. It's not mega huge though, good fit with some room for extra layering which is what it's all about.

    Very thoughtful with the pockets I must say. Alot of jackets these days especially Arcteryx have no chest pocket and small packet openings. The Rab is perfect. Pocket openings are large for gloved hands and there is a chest pocket for someone like me who needs a chest pocket for my eyeglasses to read maps or my phone etc and back of my camera as a photographer. I broke my eyeglasses last year in Japan just before I went out putting my snowboard boots on because I had to keep them in hand-warmer pockets in a different brand jacket. So chest pockets are KEY (RAB, keep up the thoughtful design) especially for big mountains, like Chamonix, etc. It is essential. There are two other internal pockets too both zippered.

    Hood is great, a big fully featured hood with three adustments - perfect. Scuba hoodies suck. Like I said when you are out there really doing the stuff, you need adjustments for the hood, when the wind blows, when it's blizzard conditions, it's is essential and RAB kills it. I would say the hood might even have too much down in it, but that is really just picky. This jacket is the real deal for real life in really harsh conditions.

    Design and color insanely good. It looks super cool too. I got ebony with lime green interior (pockets too) and just a stunner. I like my jackets to look cool especially for when I'm done apres ski in Courmayeur, Chamonix, Switzerland, Japan, Couchevel.. etc... Form and function.

    I would not hesitate to buy this again whatsoever. To reiterate: Thoughtful design, good pockets with large pocket openings for gloved hands, chest pocket (key), great hood with three adjustments and it's very warm and it breaths by the way, the inner material is really lightweight and looks really cool.

    yet another quality product from RAB

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

    I bought this jacket for my dad for Christmas to replace his old Mountain Hardware Kelvinator, which he was never extremely happy with (he wore it on our climb up Mt. Rainier last summer and was upset with how poorly it performed in windy conditions). The Infinity has really good quality, water repellent down which makes it warm and practical in harsh environments--perfect for his mountaineering pursuits. The hood is helmet compatible, which is a huge plus for climbing or skiing, and the jacket compresses really nicely as well. Not only is the Infinity perfect for spending time in the mountains, but it also looks great and is an awesome jacket for casual wear around town.

    THE VERDICT: Dad loves it, daughter is jealous. You should probably buy this jacket.

    Darn Fine

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

    I tried on all the high end down coats at the Backcountry warehouse just west of SLC, UT ( very patient and friendly employees there). The Rab fit me the best, had excellent loft/warmth and very usable cut for everything from loafing to work to needing it camping. I'm not saying that it is solely an inferno; I've been impressed how comfortable it is up to about 50 degrees. Walking around a store in the winter with the front open is pretty comfortable.

    It does well as a packable near infinite barrier to the cold. I got stuck on some hot springs and didn't really have a torso underlayer to walk the 7 miles to the car after dark and -5 degrees F. I just put up the hood and sinched the waist. The wind was a little chilly at times but I felt fine generally. It saved many parts of my body that day, most especially my a**.

    Does the infinity have the same feature as the Neutrino Endurance to be able to strap down the hood when you are not using it? Besides the front pocket what are the differences between the two models? Thanks

    Best Answer

    Hey Aja- The Neutrino is a warmer jacket, and it runs a little longer,

    but both are simply outstanding jackets, I own both models and am very happy with them. I would say you could wear the Infinity down to 25 degrees(without a layer), and the Neutrino lower than that. They are both very warm though. I got one as a X-mas gift and decided to hold onto it. You'll be well served with either coat, you'll just need to layer up a bit more with the Infinity Model.

    the picture makes it look like either the...

    the picture makes it look like either the sleeves are long or the waist is short. Does anyone have a comment on fit?

    Best Answer

    I have found that the sleeves are unusually long which makes me consider returning it. Additionally, a previous commentator stated that the down was NOT hydrophobic, which is counter to what the product manufacturer states on its website. So either he knows something that he is privy to or he is misinformed......
