Here's what others have to say...


great for any outdoor sports!

  • Fit:True to size
  • Height: 5'10"
    Weight: 180 lbs
    Size Purchased: medium

just got a pair of these and am most impressed. They definitely stabilize the muscles in the legs and give added support to the knees. Highly recommended!


Bit long i think

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:Runs large
  • Height: 5'5"
    Weight: 200 lbs
    Size Purchased: large

I just purchased them for skiing and haven't worn them execept to try them on. They seem a bit long for me where the crotch hits the bottom of my jewel sack and the knee sockets aren't
in place. Yes I am short. Hopefully it will work out in the wash and shrink to fit better. I have slack in the legs and really not sure how comfortable they will be. The Spyder Captain 3/4 fit one hell of a lot better in this size


My favorites

  • Familiarity:I've put it through the wringer
  • Fit:True to size
  • Height: 6'0"
    Weight: 235 lbs
    Size Purchased: XL

Haven't skied without them since I bought them in 2013. As noted, they are not extremely warm, but under my Goretex Pro Shell pants good to down to about 20 degrees F and then only a bit chilly on the chairlift. Lower than that, I have a pair of "shants" that go down another 10 degrees. If really cold, I have a pair of thin fleece 100 weight 3/4s to put over them that works to as cold as I want to ski -- feet will freeze before legs.


Never go skiing without these!!

This is my second pair and after trying these the first time over 5 years ago,I will never go without. They give great support,you feel "locked in".They add staying power to your legs as they reduce fatigue and are very warm.This is all I wear under my ski pants.Sizing is important so buy with care.The 3/4 length is ideal for skiing as there is no hassle with stuffing into boots and causing problems. A must have for any serious skier!


Only base layer I ride in

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

These things are ridiculous. I have a surgically reconstructed knee, and these pants provide a ton of added stability. Got rid of al my other base layer bottoms--only thing I'll ride in anymore

Any idea of sizing for a 5'9" 205 lb'er with a 36-38 inch waist. I notice I am off the cw-x chart for large and xl at this height/weight combo.

I would go a size up, so if you're normally a L, go XL. I could barely get them on when I bought my normal size. They were REALLY tight. Buying a size up are still tight, but I can breath.


Fantastic as Expected

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

Had to write a review post 7 days of boarding with these and use the fantastic adjective as there was 2 ft of new powder!

Obviously, this is independent of the tights so back to my review. I really like the 3/4 length because it doesn't interfere with the fit of my boots. My other pair of CWXs are not insulated and I was able to lose a long underwear bottom because they are very warm. The insulation is fleece like.

I don't know if the compression actually works or I just believe it does. I can say that on 2 of the days it was a very heavy snow and there was so much snow in the woods it was difficult to get back up when I fell. My legs were somewhat sore but I think it would've been a lot worse without my CWXs.

I would definitely recommend these!


Good for knickers, but...

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

I don't get it. If you need tights wear tights, if you need shorts wear shorts. I'm either a little too cold or a little too hot in these. And I tried to like them real hard, under ski clothes, under dry-suits, on the bike. I love my CW-X full length stabilyx, but these sit un-used now. Maybe I'm just not a capris kinda guy.

I found the opposite situation for skiing. The seams of my full-length tights were irritating my ankle, even though I tried to position them behind the bone area. A bootfitter recommended nothing but socks between my leg and the boot, so now I'm looking for a pair of 3/4 length.

I agree with trw. I am a boot fitter and recommend 3/4 base layers to everyone. I use these compression pants and they are phenomial. reduced fatigue, good circulation, good moisture management. Ski in them all day long under my ski pants

agree w/trw as well. the seams of the full length were irritating my legs. going to 3/4 fixed this

I had the full length and went to 3/4 to keep them out of the boots. Socks go up over the bottom of the tights so there is no exposed skin. I suppose in looser snowboard boots it might not matter, but in performance downhill ski boots you don't want an extra layer in the boot.


The best compression 3/4 tights I own

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

The top side of the legs is fleece-like on the inside and the compression bands are made of a strong, stretchy material. The underside is mostly a strong, stretchy, material, but without the fleece. There's a mesh panel in the front torso area.

I really felt that my knees were supported and I like how generous the rise is. These keep me "locked-in" so to speak. Since buying them, I've done 3 half-marathon -and then some- length runs in disagreeable weather and have been glad I wore them.

Is overall length consistent across sizing?...

Is overall length consistent across sizing? That is, would a small be slightly shorter than a medium? I'm considering size small - I'm 5' 11" with a slim build. I don't want to loose out on length if a small is shorter, but am afraid of a medium fitting too loose. Any thoughts?

There are very minor differences in length between sizes (about and unstretched inch). The majority of the difference is in volume and waist size.


Snowboarding Base-layer

    As it says, I got these as my base-layer for snowboarding this year.

    First, sizing -- I fall in the Large sizing on the CW-X chart (6'1" 195). I have a pair of the full length non-insulator in the large....I got these (the insulator 3/4) in a medium...A LOT BETTER. Gave me the advertised support and compression (plus no bunching). Now, I am not a skinny legged person so don't even try, in fact, I have problems with regular pants because I have very thick legs from years of football, squats, and powerlifting.

    Form and function -- 4 days of hard boarding and I'll say they earn their keep. The support webbing gives me the stabilization on my battered knees and also give you some hip-flexor support for those hard-charging downhill days. Now I can't say if for 100% the compression gives you any more endurance, but I can say you do feel an extra spring in your legs and I was able to get some very long days on the slopes prior to my legs giving out. Lastly, they stay in place with you socks pulled up over the bottoms.

    If you have issues with stuff in your boots, go with the 3/4. Me as a boarder, I'll probably go for the full-length next time since I find my calves take a beating and the 3/4 don't get your calves.

    Insulation -- NOT the warmest thing, in fact, I do feel a little chill on my legs through my pants when I'm not moving (for reference: Columbia Men's Ridge 2 Run II pant). Lowest temp in the teens, once you get going though, these are the perfect insulation. WIth my non-insulated stabilyx I mentioned before, I would have to wear fleece shorts or a loose base-layer over top of the tights...not needed with the insulated version.

    Bottom-line -- Stabilizes your joints and muscles along with giviing you compression for (theoretically) lactic acid recovery. They are expensive but if you need this type of product, it's worth it...just consider how much you spend for other clothing that aren't as functional in terms of performance.

    P.S. I got the CW-X 3/4 Thermals over the Skins Thermal Snow tight (3/4). The CW-X 3/4 come down past your knee far enough to stabilize the joint and not roll up on you. But...the compression was a little better in the Skins (same size). All said and done, the CW-X was better all-around.
