Get It Before Labor Day Weekend—Order With Free 2-Day*by 5pm MT 9/2/15


A technical shell pant that keeps up with your mountain mayhem and doesn't slouch on style.

No matter how cold and snowy it gets, when you move fast enough, you have to let your boys breathe. The FlyLow Gear Chemical Pant keeps all the pow out during big lines but lets in a cool breeze during the skin back up the ridge. Since you slay big lines and deep snow on the daily, you'll be stoked on the Three-Layer Intuitive Fabric in this shell pant. And since you work for your turns, this pant's inner and outer thigh vents get you all the ventilation you need to keep skinning and lapping your favorite zone.

  • Thanks to a tough nylon shell with fully taped seams and a Level 5 Dupont DWR coating, you get water-bounce and breathability for maximum big-mountain backcountry performance
  • Cordura reinforcements on the knees and cuffs reduce wear from edges and tree encounters
  • Adjustable waist tab secures the pant during big drops and walks across the parking lot
  • Three-panel construction on the knees provides an articulated fit that's ready for charging
  • Relaxed fit optimizes range of motion and allows ample layering on the colder resort days
  • Ykk waterproof zippers keeps your inner layers from getting soggy

Here's what others have to say...

I'm 5'9 and 197lbs with a 36 in waist. should I go with a large or xxl in the Flylow Chemical pants.

Responded on


I'd say with a 36 waist, you're on the edge of both sizes. For me, it would come down to whether I prefer a tighter pant or a loser pant.

So if you want a tigher pant, go Large. If you want a loser pant, go XL.

Too baggy & too short

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Height: 6' 1"
    Weight: 185 lbs
    Size Purchased: large

This was my 6th pair of Flylow Chemical pants, going back to the originals. Sadly, this is my last pair, and I've returned them. Each year, they get baggier and shorter. Not bro baggy, which is bad enough, but oddly, inexplicably baggy. Right below the belt loops on the outside of each leg, Flylow began adding an extra yard of fabric a couple of years ago that has no discernible function: it doesn't make skinning or skiing in them any easier or more comfortable. It's just extra fabric that pooches out noticeably to each side and makes you look wide and pear-shaped(and I'm not that: 6'2" / 185 llbs) and just plain silly. And they've gotten a little shorter each year as well, so now they're just too short. I haven't changed, but Flylow has. So they're not for me anymore. The Outdoor Valhalla pant fits and looks and works almost exactly now what Flylow Chemicals used to be. Too bad.

Unanswered Question

Interested in these and the Magnum Pro for mostly frontside skiing. 5'9" and 180lbs. Thinking size large. Any product preference?

Im 5'11" and wear a 34" waist pant. Anyone have any sense if I should go medium or large? Feel like I'm right on the cusp.

Responded on

The large would fit you best in these pants. The medium would fit but would not allow much room for layers underneath. The large would allow more room for layers and the 32 inch inseam would fit you well.

6'1-6'2, 33 waist, 180 lbs. Large?

Responded on

Hey, Large will be perfect!
I'm 6'2" 175, 32waist, I do have to wear a belt. and the length is perfect! Medium didn't fit me correct.
I love these pants. I have the bibs too.
Hope that helps!

High Quality with Lots of Vents

  • Familiarity: I've put it through the wringer
  • Fit: Runs large

I ordered these in XL. Main selling point for me was the product quality and number of vents the chemical pants have - great for dumping heat while touring. Knees and ankle cuffs are double reinforced and have held up great. Surprised to see how large they fit especially since I ordered up a size on my Higgins coat, which seems to run small. Overall, I definitely recommend the chemical pants.

Built like a tank, perfect fit

  • Familiarity: I've put it through the wringer
  • Fit: Runs large

Evidently this is the product that put the company on the map and we now understand why. The design has changed little over the years and is a testament. These are just superbly designed pants that are built like a tank. One great change was the 13/14 upgrade to the same 3L, 20k/20k Intuitive fabric as the Quantum Jacket. This results in a noticeable increase in waterproofness with a decrease in weight. With this rugged fabric and articulated, reinforced knees, these pants will likely last years, without being heavy and cumbersome. With a slightly baggy fit, these are the lightest feeling, most well-fitting, comfortable pants we’ve worn in years – actually – ever! We say “baggy”, but not like park rat pants, just enough for total freedom of movement. Add “through” ventilation with thigh vents inside and outside, large zipper pulls, a heavy duty “jeans” style front button (instead of the dreaded snap) and belt loops (missing on many brands) and you have the best ski pants on the market today. Minor critiques: none

Built like a tank, perfect fit

wondering what size to order. I'm 6'4"-220...

wondering what size to order. I'm 6'4"-220 lbs. I own patagonia untracked pants in a large that fit well(maybe a hair short). should I go with L or XL? thanks

Great pants!

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

This is a very well made and designed ski pant. I highly recommend.

Ok I Guess

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

I purchased these as a replacement for my TNF Freedom Pants, which I've had for a long, long time. Based on all the great reviews, and the price, I guess I was hoping to be wowed by these. But after a couple of uses, I have to say that they're nice pants, but nothing spectacular.

- Seem to fit true to size (I'm 6' 1", 220 lbs and a XL fit well).
- Burly knees and cuffs
- Pretty stylish

- Knee reinforcement area seemed to be just a little low on me, so the top of it keeps catching on my knee area and irritating
- Pretty thin material - definitely need a thick baselayer underneath.
- No mesh liner in the vent zips
- Cost

I really wanted to love these pants, by after several uses, I don't really see the point in dropping a couple of hundred more bucks on these over my tried-and-trues.

Love these pants, but too short

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

I really like the material, the style and the functionality of all of the Flylow pant models (I have used or at least tried on every model), the only problem is they all have an unusually short inseam. This may not be an issue for average size guys, but for any of you that are taller (+31.5" inseam) but have an average waist (32"-35") these pants likely will not fit well.

I'm in Colorado, I love this local band and their success story. I just wish they would offer a long size option.

Big vents, bigger knee brace

the huge vents make adjusting a knee brace a snap. Dumping heat is a plus also

Patrolling Pants

I use these every day on Ski Patrol. I heard this year's model uses a thinner fabric than prior years and isn't as well built, but I don't have experiance with them before this year so I can't comment on that. I have probably 60-70 days on them this year and they have held up reasonably well for the abuse I give them, a few cuts down on the legs but nothing huge. The left large outside vent zipper comes appart unless I have one of the pulls all the way at the top which is my only real complaint so far. They are comfortable and it is hard to find a pant with reinforced knees such as on these. I spend a lot of time kneeling at work doing patient care and the knees on the pants are still in good shape.

almost perfect

  • Gender: Male
  • Familiarity: I've put it through the wringer

The best ski pants I have ever owned, and I've owned a lot! The size large is just a little too short to cover my Scarpa T-1's past the second buckle. I'm 6'1" with a 34" waist.

I'm 5'7, around 145-150 lbs., and my waist...

I'm 5'7, around 145-150 lbs., and my waist measures 31". Should I go with a Small or Medium? Thanks.

Responded on

You are right between the sizes, so you could go either way, depending on how you like the fit. There is a sizing chart below the price that may help.

Responded on

Thanks a lot for pointing out the sizing chart. Based on the chart I think the Small might be the better option. I like a relaxed fit, but don't want them to be falling down.

Tough as Nails, yet lightweight

I've been looking for pants like these for some time. I ski pretty agressive and my lower pant legs get sliced up constantly. I went through several pairs of Markers using Duct tape and tent seal to fix the slices. I then went to a pair of Descente pants with rubberized cuffs on the inside legs. these work well, but the cuffs are only 6" high, and I needed something that covers about 10" of height. I found these pants and they are unbreakable. I skied them in Utah last week and they took heavy abuse in the cuff area, with no slices whatsoever. The full zippers are also an extremely useful feature. The one thing I did like about the Descente pants over these are that these are not as warm. I never got chilled but in very cold weather I think they would not be as warm.

Well worth the money I paid for them - less expensive than my Descente's and tougher.

Insane Pants

If you think Carhartt work pants are good, these are like those but for the mountains. Best pants I've ever owned in 20 years of skiing. Everything about them is sweet
