Some might call the FlyLow Men's Quantum Jacket an everyday, technical workhorse. Those people would be correct, because this jacket is the toughest and most technical jacket made by FlyLow. Beefy fabric is match to burly weatherproofing and massive underarm vents, an ideal mixture of features for a jacket touted as a one-stop solution for your entire winter.

Great but..

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

Loved everything about the coat! Color, fit, function, features but the stitching on the outside oft he pocket came out after 3 days of use. I know they would have replaced it but I fear it won't hold up to the 120 days of skiing in a season! BUMMER!

Free Yourself.

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

Essentially, for me, this is a completely worry free jacket. I don't want to have to think about my equipment, and this jacket is so solid I don't have to. I don't have to worry that my jacket might tear if I shred through those tight trees. I don't have to worry about getting soaked on the wet days. I can just ski. It's freedom in the form of a jacket.

There's really nothing bad I can say about this shell. It's pure beef. It's burly, bombproof, and fits better than any other jacket I've tried. The fit is perfectly relaxed in the torso, and the sleeves are nice and long. Perfect for layering as needed, but plenty of style for those laid out backies under the lift.

I'm 6'1'' and a Large is great for me.

A lot of companies say their hood will fit a helmet, and it may be true. But very few hoods allow good enough range of movement over a helmet. The Quantum nails it here too, and on insane weather days here in North Idaho, I can still shred just as hard while staying protected in my hood. Also, there's no mesh liner in the pit zips, which is amazing. Mega heat dump without getting any mesh stuck in the zippers. Simplicity.

The pockets are all perfect, and the junk trunk pockets are genius. Throw in a sandwich and a beer for the lift ride, your skins, extra glove liners, whatever. It will fit.

Free Yourself.

Great shell for skiers

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

You can tell this shell was designed by actual skiers because of the little details and how it fits. I'm 5' 11" / 170 pounds and always stuck between medium and large sizes depending on the brand. I went with the medium and it's perfect - plenty of movement without restriction, just long enough, but slim so it doesn't feel bulky. Also, it's amazing how few jackets / shells can be zipped up fully while still leaving adequate room for your chin, especially while wearing a helmet. Paired with a Patagonia nano puff base layer and I'm plenty warm.

Great jacket value

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

Flylow is in vogue as of late, and I jumped on the bandwagon. I have skied more expensive jackets and this jacket has the same fit and finish for about 1/3 less money. My only complaint is that the sleeves could be at least an inch longer in size Medium. I initially bought the Large, but it swam on me.

A Dang Great Jacket

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

This is a bomber coat that is both aesthetically pleasing and functionally sound. Just the right amount of bells and whistles without sacrificing the simplistic function that it's shooting for. As far as hardshells are concerned, this is my favorite jacket to date and I will likely only replace it with another Quantum. Likely not for a good few years though because these are built to last.

Good jacket, but lacking a bit

    Well it's a solid jacket; good for layering under, fits to size and keeps me dry. Still, I had to treat it regularly to keep water from saturating the outer fabric...far more than I did with my last jacket (Arc'teryx). What bugged me most was the lack of pockets, particularly a sleeve pocket. I'd recommend it to most people, but I'm just tend to nitpick these things. I'll be upgrading to another fully waterproof jacket, but will keep the quantum for hiking/skinning, as it does breathe and vent exceptionally well.

    Serious Jacket for the Sporty Type

      I have been free skiing all of my career and rarely have I come into a jacket of this stellar quality and durability. Great technical design for the serious skier who never wants to think about a jacket failing while touring (my past 2 jackets were from Salomon - epic fails). I am 5'9 - 185lbs - 42' chest - medium is the fit with plenty of room for layers or sweater jacket. I typically see about 60 days a season and this jacket will be with me for at least 5 seasons. Light, durable, taped zippers (tough also), killer skin pockets inside(smart), 2 deep front pockets for ipod/radio, powder skirt with real metal snaps (not that plastic sh$t that salomon uses). The calibre of this jacket rivals that of Arc'teryx but at fraction of the cost. Minimalist design yet just what I needed. tx Flylow!


      Great jacket!

      • Familiarity:I've put it through the wringer

      I have last years (green). It is VERY green. I like the thought that went into this jacket: great pockets, huge pit zips, capacious hood. For a hardshell, it has a "soft hand" and feels a little stretchy: much less crinkly than my older Arcteryx. My only 2 "gripes" (which aren't really gripes):

      1) I like a small sleeve pocket, which this doesn't have

      2) the fit is a bit baggier than I'm used to. I'm 5'7" 150 lbs and I swim a little in the M although of course that's great for layering warm stuff.

      Good job!

      At a year followup, I still go for 5 stars. I use it WAY more than my other comparable jackets (Eider and Arcteryx). Good waterproofing, I really appreciated the big inside pockets for skins, and the hood really covers my helmet without being intrusive. Plus (I know this is kinda nitpicky): when zipped up fully in bad conditions, it doesn't pinch my chin or feel too tight around the neck as the others do. I can still turn my head freely so I tend to leave the hood on. I have several other flylow bits (baker bibs, vest, gloves) and have really found them to be my favorites items right now.

      quality is seriously lacking

      • Familiarity:I've used it several times

      after having my car broke into and losing my fav jacket I decided to try this Fly low jacket. The stuff looks good and the features and fit are really great. Just got back from an early season Mammoth trip where I used the jacket for four days on the hill. Got home and decided to wash it as I got pretty hot and steamy in the thing (doesn't breath too well). I was surprised to see the inside taping coming undone in a few spots. Cool stuff but ain't so cheap anymore and at $370 you'd think it would be some serious quality. Get it together FlyLow!

      Better than imagined!

      • Familiarity:I've used it once or twice and have initial impressions

      I just spent the weekend living in the Flylow Quantum Jacket. I was looking for a basic roomy shell for layering and handling a range of conditions (MN). Went from hockey rinks, to running errands, snowblowing, and shoveling. Didn't get hot, didn't get cold and only wore a heavy wool sweater for insulation. My biggest problem in coats is fit, and I took a chance and ordered the Quantum = homerun. I'm 6'2, 250 lbs , 36" waist with wide shoulders, longer torso, and long arms. The XXL fit for me is perfect and I have plenty of room for one/two layers of insulation. Breathability of the coat was in a word = awesome. A couple features that I really like are two ext. chest pockets and the lower waist pockets are cavernous. One clever design is how the snow skirt ends tuck into triangular pockets and snap in place. The Red coat with tan zippers looks good, received several compliments on the jacket to my surprise. The red is on the darker side compared to what THF or Marmot would use, but it's a nice change from generic safety red most clothing companies use. Not as bright as the Backcountry website shows. Fabric has a nice finish, but is a little on the crunchy side noise wise.

      "if you have the means, I highly recommend it"

      Best Backcountry Shell

      • Familiarity:I've put it through the wringer

      Traditionally I always have used Gore-Tex in Marmot products up until a few years ago. I had some durability issues with pants in particular and was extremely happy with how my Flylow Magnum pants withstood the bushwhacking and backcountry abuse. The fit is baggier than I was used to, but after I began using it I realized the fit was much nicer to layer with if I wanted and was much more comfortable. It is not 100% waterproof, but its just about as close as you can get. I've only had water come through the shell one day skiing in a rainstorm for 6 hours. The features of the jacket are great. Perfect pocket placement, a great powder skirt, plenty of storage, and the only jacket I have ever owned that I can actually ski with the hood over my helmet. The shell has a ton of versatility and can be used almost all year in foul weather. Very breathable on the skin track! Phenomenal product.

      Best Backcountry Shell

      Just a followup to my review. After two years in the coat the main zipper broke while out touring. Ended up resulting in an uncomfortable day. The old style zipper that is a YKK sucks. Flylow can repair them, but its pretty unfortunate if it happens mid season. My recommendation would be to have a backup coat for the winter in case this happens. Ended up purchasing the Lab Coat on clearance and it has a much burlier zipper.

      My favorite jacket

      • Familiarity:I've put it through the wringer

      We have been designing and making clothing for 7 years now and this is the toughest, lightest and best 3L shell we have made. I am 5'11" and 180lbs and the LG fit great. Plenty roomy for layering with a puffy on a cold wet day and not too big for touring with just a base layer. The huge vents come in handy on the touring days and toe powder skirt zips in and out depending on depth...

      Style, Function, Duribibity!

      • Familiarity:I've put it through the wringer

      Full Disclosure, I'm a Flylow athlete. I've been using Flylow jackets since the original Lab Coat (Flylow's first hard shell) and the Quantum is by far the best jacket to date. I put over 100 days on mine last year and it will easily go another 100+.

      Pros: Durable, waterproof, great fit, huge inner pockets (i use these for skins, or beers), huge pit zips,and helmet compatible hood.

      Cons: Can't think of any

      Sizing: I'm 5-9, 155lbs and I wear a large

      I just bought the Quantum jacket, haven't used it so far, but thought I would comment if people were looking for sizing feedback. I'm 5'8" and 150-155 lbs, 39-40" chest, and found the medium was just about right. The sleeves are a little longer than I would like but will probably appreciate it once I layer up. My sleeve length in dress shirts is a 32/33 if that helps. Can't wait to try out the new jacket this season!

      Best Bang for your Buck

      • Familiarity:I've put it through the wringer

      I wasn't too sure about this coat when I bought it. I really wanted to buy an acteryx coat, but could not justify spending twice the $. I had never heard of "Flylow" before, but I have been very impressed with their commitment to quality, and making a coat that I feel like I can do anything in. This coat has changed the way I layer and prepare myself for spending a full day in the mountains. These guys really do spend time designing their products. The other mid layer coat and vest fit perfectly under the quantum and keep me toasty on the way down and well vented on the way up. Well Done team Flylow!

      Decent quality bad fit

      • Familiarity:I returned this product before using it

      Seemed like a decent quality jacket, but I had to return it because of the fit. I'm 5'8, 160lbs and i ordered the medium. It was roomy in the torso but too tight around the neck when zipped all the way up.

      What color pants do you recommend for...

      What color pants do you recommend for Indigo Quantum jacket?

      Do you think sulphur yellow (Scott) or bright electric blue (Norrona)?

      Trying to determine size for Quantum jacket...

      Trying to determine size for Quantum jacket and FlyLow pant at same pricepoint. I wear size large in Patagonia and it fits comfortable as do their pants, bordering on loose in the waist. I have 33-34" waist in jeans with 32" inseam, 5' 10" and 160 lbs. Does FlyLow run the same as or larger than Patagonia for the same size.

      This or the Patigonia Powder Bowl?

      This or the Patigonia Powder Bowl?

      Personally I'm a big Flylow fan. Products are super durable, have a good fit (6'2" 180lbs, Size Large) breath well and have skier\snowboarder features. And they're a small local company.

      I don't fit well into Patagonia's sizes well, they're short in the body.

      Anyone have a picture of the red jacket?...

      Anyone have a picture of the red jacket? Looks a lot darker on the flylow site than on here. Thanks!

      I spoke with Dan at Flylow and the darker red on the Flylow site is most accurate. The jacket is not bright red as shown on this site. I did get the impression from speaking with both companies that the color may be somewhere in between.
