    Leave your own chemtrail.

    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. But the goodness doesn't stop there—FlyLow added super burly Cordura reinforcements along the knees and cuffs to keep this pant in tip-top shape whether you're dropping knees on a deep powder day or boot packing up rocky ridge lines en route to a big descent.

    Decent pants

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'0"
    • Weight: 195lbs

    I bought these pants at the beginning of last season and have put over 50 days on them. I have done everything from lapping the resort to hiking couloirs in the backcountry. I have gotten 3 holes in these pants which I have patched using a combination of tenacious and gorilla tape. So far I have experienced no leakage. I like that they breathe well and have full venting however I do have some issues with these pants. I find the waist tight and restrictive where the rest of the pant fits great. To solve this I keep them as loose as possible and use suspenders. I have also been disappointed in the durability. In addition to the holes the fabric on the the front thighs has pilled from falls. I would give these pants a 3.5 if possible.

    Decent pants

    Great ski pant, especially for the money

    • Fit: True to size
    • Size Bought: XL
    • Height: 6'2"
    • Weight: 195lbs

    I originally ordered this pant in a large based on the comments others have made about sizing. I am 6'2" 195 with a 35" waist and immediately found the pants too small. My Gearhead was great in helping me return them, create a credit and order the XL. I got the XL size quickly and when I tried them on they were perfect. I cinched the waist straps and wont need a belt. The length is also great, I am more leg than torso and I was worried the pant would be too short but when I put them on with my ski boots they were just right. I ski about 20 days a year and am not interested in paying high prices for something simple like a ski pant. I have 2 other Flylow products (Down coat and vest) and wear them all the time. When I started shopping for ski pants I went straight for Flylow as I know I wont be disappointed or pay more than I should have to.

    Love em!

    The chemical plant is kind of like a futuristic version of your favorite pair of Carhartt pants. These pants are DURABLE and really waterproof. They have huge vents for when things get hot on the skin track, or when the dancing gets heated during Apres. The best pants I have owned hands down.

    Favorite Ski Pants

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: med
    • Height: 5'9"
    • Weight: 155lbs

    These pants are super burly, but aren't heavy and clunky. Mine have held up through multiple seasons of skiing, and are still super waterproof. The huge zippers also make hiking/touring a breeze. Love these pants.

    Waterproof and well-vented

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: xl
    • Height: 6'3"
    • Weight: 195lbs

    I am 6'3 and about 195lbs, and I find that the xl fits me about as well as any ski pant I have even owned. I have skied approximately 25 days in these pants, mostly in deep snow in the Wasatch range, and I have the following observations:
    -thoroughly vented, and probably the best pants for hiking for turns I have ever owned
    -dwr is spot on, and I have yet to have these pants soak through
    -flattering fit, and don't look super obvious as ski pants if you stop for a beer after the mountain
    -not the warmest pants I own. When the wind is howling, you'll notice. This might be a result of the pant being super thin
    -they definitely require a belt, as the velcro tightening system is basically useless

    Amazing Ski Pants

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Medium
    • Height: 5'6"
    • Weight: 185lbs

    I put over 100 days on a pair last season and they barely look used. Burly fabric and construction but super comfortable with a perfectly baggy fit on me. My other ski pants were severely neglected this season with these proving flawless in all conditions.

    Appear to be very good

    • Fit: True to size
    • Size Bought: Large
    • Height: 6'2"
    • Weight: 207lbs

    I'm 6'2 and weight about 207, which is a little heavier than I like to be. I got the Large. While they fit around the waist, they will be much better when I'm back down to 195-200. I'm a 35/36 waist at the moment; normally a 34/35. There is no room for expansion, whereas the larger size would enable me to close the velcro adjustable straps on the sides. I think the XL would be too big & baggy. I've got athletic thighs and they fit perfectly in the legs. Others complain about the bagginess, but I think they're great for ski pants. The length is perfect. They appear to be well-designed. The buttons on the front do not poke me as mentioned in another post, but I haven't put on a backpack with waist strap to test it. I bent over and tried to pinch myself, and couldn't feel them. I like the leg zippers on both sides. Very good design. I've historically worn North Face pants, and I can tell that these are going to be as good or better, depending on actual wear and tear. I got the ocean color, and it's true to the picture displayed (or as close as you can get with a computer picture). I like them alot...won't know for sure until ski season gets here in another 4-5 months.

    I bought these to be a waterproof black uniform pant for patrolling but ended up just wearing them every day. Waterproofing is flawless and the leg zippers keep me from overheating when I have to dig out tower pads.

    Perfect for any day

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XL
    • Height: 6'4"
    • Weight: 220lbs

    I absolutely love these pants. I'm 6'4" and got the XL. They fit perfect and have that baggy feel that not too many brands have. It's not overly baggy but you get the idea. The zippers on the outside allow for easy airflow when it's too warm and the knees have an extra layer to keep it durable.

    I broke these bad boys out in park city last week and they got over 40" of snow. They held up amazingly well and kept me warm face shot after face shot.

    This if my first purchase from Flylow and will be buying these again if/when these wear out.

    Whats with the buttons?

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: Small
    • Height: 5'10"
    • Weight: 142lbs

    They have big protruding buttons to hold on the front belt loops (just sew them?!) They sit right where your waist belt of your pack rests digging them straight into your hip bones. Great pants but this HUGE flaw makes them almost unbearable. I've had 100's of days on two pairs of these but no longer can I take having to pull my pants up above my waist belt every 2 minutes during a tour. Stupid, stupid design.

    Gaiters Are Too Short

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: Medium
    • Height: 6'
    • Weight: 175lbs

    I really love these pants. They look awesome, and they are really well constructed. I really want to hold on to them and make them my go-to pant, but I think I will ultimately return them. The gaiters are just too short, barely making it over the first buckle of my boot. The elastic on the gaiter is not that taught, and it doesn't have a hook to attach to your boot. The inseam on the pant is the right length, but the gaiters are just too short.

    Fell out of love... not long lasting

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

    I really liked these pants at first. The fit is great, the fabric is light and comfortable, and they feel burley. Within a month of skiing on them I have beaten them up badly. They already have torn in the back and the fabric is barely waterproof. Disappointed these didnt last longer. It was my first non-gore tex pant in a while, and now I know why... Wouldnt recommend.

    Tall people suck

    • Size Bought: Medium
    • Height: 5'7"
    • Weight: 190lbs

    I bought these because I wanted a burly yet breathable pant for every day use at the resort (too heavy for skinning), and so far they seem like they will do the trick. Great venting, nice adjustability on the waist with the velcro tabs, and simple waterproof pockets. That being said, I know Flylows whole style is the baggy look compared to the more refined slim mountaineering look from brands like Patagonia, and I'm ok with that, but these are just too long for me. Really, it's no surprise there. I've never seen a decent quality ski pant that comes anywhere close to my measured pant size of 34x29. 34" waist is almost always a size medium ski pant, which for Flylow, and most others, is a 32" inseam. For ripping the resort, I don't mind the little bagginess around the seat, thigh, or knees but all the folds of extra material bunched up around the cuff are annoying and look ridiculous. Please, Flylow (and everyone else)make top-notch ski pants with a short inseam option!

    Best snow pants ever

    • Familiarity: I've put it through the wringer
    • Fit: Runs large
    • Size Bought: L
    • Height: 6'1"
    • Weight: 200lbs

    I purchased a large in these instead of my normal XL. Great recommendations from reviewers because large was the way to go.

    These are a very baggy fit style pant. Make sure that is what you like before you order.

    I have taken these on many trips but my first demonstrates it's performance. I took these pants to a weekend trip to Lutsen with my family in February. During the trip we had a blizzard but were insistent on getting to the mountain. Most of the day we were lucky if we could see 50 ft in front of us, often we couldn't even find the lift. The snow was very large, wet, and heavy. The snow would melt as soon as it landed on you. Everyone in my family got soaked to the bone within an hour. I destroyed a brand new pair of snowboarding mittens it was so bad. This pants kept me dry the entire day with no sign of failing. They have venting on both sides of the leg to cool down, it is not common to find this. Tons of "polymer" reinforcement in areas that commonly fail on snow pants.

    The quality is outstanding.

    I've been snowboarding for almost 20 years and have never owned better pants. Will buy these again when I need new ones.

    Seriously tough

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

    First these things take serious abuse. I am out on my snowmobile a lot and between riding and digging most things take a lot of abuse. These don't even flinch. Even after heavy use they have zero tears in the material- can't say that about any other pants I have ever had. Second; I used to be total convert of bibs. That is until I met these pants. The cross ventilation really, and I mean really works. When skinning these things open up and give me a few different levels of how much venting I need. I used to be gaga for bibs because they never bound up and gave me unrestricted stride when skinning. The chemical pants do the same- they stretch! I also really like a back pocket zipper for my wallet- why I keep my wallet on me in the backcountry I have no idea, but its nice to have the option. These pants are the best of both worlds, tough as nails yet totally unrestricted touring movement. They do not do so hot on the waterproof front. Have gotten these soaked thru and thru on day of riding.

    Seriously tough

    You can't go wrong with Flylow.

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

    These are the second pair of Flylow pants I've owned and they've yet to disappoint. I've only used these particular pants a handful of times and haven't had a chance to see how they do in full-on storm conditions, but my initial impressions are these are well-made pants and will take a beating either in the resort or in the backcountry. The knees and cuffs are reinforced with a Cordura that looks pretty much indestructible. The outer leg zips are killer when you need to lose some heat on the skintrack. I also really like the adjustable waist since I don't really like wearing a belt when I ski. They do fit a little baggier than most ski pants, if you're into that sort of thing.

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


    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.

    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.

    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.

    disagree repectfully with Dan...have owned a few pair and the large will be like a sail on you. If you like wearing them lower toward your hips or have a ahorter inseam size medium regular is fine. If you have longer legs and wear them a little higher order a medium-tall from Flylow.
