These tights are great. They offer superior support of the knees as well as the hamstrings. They are sufficiently thick and provide great warmth. The 3/4 length is perfect for skiing as they don't bunch up in your boots.

Great Skiing Base Layer

I absolutely love these tights. I purchased these after getting the full length insulated tights because I loved the support and stabilization I got but grew tired of having the sock/tights overlap at my ankle inside the boot. So these were a perfect fit. Sometimes the bottom creeps up the calf and the knee cross-section drops a little lower, but these are worth every penny.

Great Tights!

I use these tights for skiing and snowboarding! They keep my legs from getting tired and provide good support. I have had both of my ACLs replaced in my knee and these tights provide the warmth and support I need. Worth every penny!

Great support

I have wore the CW-X insulator Stabilyx 3/4 for 5 days skiing and they provided great support and my legs werre never tired and styed the perfect temperature in both cold and warm weather.

Great for skiing

There are terrific for skiing. I have a pair of the full length tights, as well as the 3/4 tights. The performance of both are terrific. You really feel the support, and true to form, your legs are not as tired at the end of the day. They are warm enough that they can be worn in fairly cold weather solo under pro-shell pants. But the 3/4 version definitely worked better, for me at least, for skiing, as they remain free of the boot. The full-length version seem to bunch up at the top of the boot. They're great too, but not for me for skiing. But definitely highly recommend these; yes, perhaps expensive when compared to something like Patagonia Capilene, but you do actually get a lot more for the price.

I would like to buy a pair of the CW-X insulator Stabilyx 3/4 tights as a gift for my boyfriend. He is 5'8"-5'9" and weighs 150-160 lbs. According to the sizing chart this puts him closer to a small than a medium. He is a medium in pretty much everything he wears which makes me hesitant to get him the smalls. But, I know they have to fit right and I don't know if the mediums would be too long. Do these typically run a size smaller than a person's size in regular clothing? We mostly snowboard in Mammoth, CA. I noticed some Canadiens said for west coast skiing they would not get the insulated pair b/c it is not cold enough to wear them. Are they just being crazy cold loving Canadiens or would the Insulators be too warm for teens to 30s weather?

I just got a pair and length is far more important that width with these. I was rgtht between medium and large in length and went with the large, clearly the right choice. They offer great support and are fairly warm.

Returned CW-X 3/4 Insulator Tights

Returned as they were too short as I'm "all legs" and not a product problem. However, they did not seem to have the support or insulation of the insulated McDavid tights that I own that are very supportive and warm.

Good mid-weight baselayer

I was able to take these out for my first day of skiing this year. All I had were these and a pair of shell bibs. The temperature was around 23 degrees with wind gusts upwards of 50 MPH. These provided a great deal of warmth and my legs never felt tired. These did not ride up and stayed in place throughout the entire day of skiing. I really miss not having a fly, but other than that a real solid pair of baselayer tights.

Good Geezer support for us older skiers/runners

Being a bear of a guy, 5'10" and 220, half my intestines removed due to Crohns disease and had a hernia last fall, these pants have been a godsend. I normally have a 40-44 inch waist depedning on time of year, and it fits all year. The compression is amazing and improved my running the first day I wore them, keeping my tree trunk legs nice and tight all the way down to where they stop at the calves. They do not interfere when its time to put the skiboots on either. They wick the sweat away as well as if it were "chrome off a trailer hitch". The only complaints are no fly, and the patch of clth by the sac sometimes makes it more comfortable to wear a pair of boxer briefs underneath them for extra support there. But even without that, you get used to them.
The compression around the gut and lower back is important for us geezers with hernia issues but is not too tight to restrict the movement you need to ski well. I haven't tried the insulated ones yet because I ski in Utah, not Mt. Tremblant, (that IS a Canadian thing, and a good reason to fly to Utah!), but the colder it gets, the more layers you add. Its not rocket science. But for those needing some real compression and have issues with shorts riding up or legs so big that they rub together when you wear the shorts, these are a Godsend! Worth every penny!

Expensive...but great

Yes, I catch some grief from ski buddies for spending this much on long underwear. It's worth it. The tights are very warm (though I haven't been out on a super cold day yet). The support is definitely solid and noticeable. As others have noted - if you need true knee support, get a brace. They do, however, allow me to ski harder, longer, with less exhaustion. My quads and knees feel pretty good at the end of a hardcore day of skiing, and the next day I'm less sore/stiff than I would be.My only complaint: the upper leg/crotch area is a little...umm...abrasive without underwear. While underwear fits underneath fairly well, it adds bulk and isn't ideal. A soft lining in the 'underpants' region would eliminate the need for the extra layer.

More support than you think

These are perfect for me under uninsulated shells down to about 15F. Above 30F, they're too hot for me. The extra support helps my thighs and back and they are not as tired as I would expect. I don't really believe the knee support hype - keep you leg muscles strong and use a real brace if you need it for your knees. Getting your boot alignment checked and fixed will help your knees more than any pair of tights. The uninsulated ones are great for warmer weather or under insulated shells. For downhill skiing, get the 3/4 length because stuffing longjohns into your boot tops will bruise your shins.

Love 'Em

I run all year in some sort of compression gear, so it only made sense to ski in it as well. The insulated version of these tights are super warm; just returned from a trip visiting family at Tremblant in Quebec where we skied in -27F windchill, (it's a Canadian thing). Never got cold. If I lived out west, I'd probably opt for the non-insulated version as I think these would be too much. However, your experiences may vary. The compression panels up around the waist really help stabilize the back, and my knees felt great all day. Buy 'em and you won't be sorry. Cheers.

Alpine Skiing

They work well for me. Sure they are not going to be as supportive as braces but that is not the idea. The idea is to facilitate support rather than provide it - like it is with Kinesio tape. The other big benefit is compression - something that Kinesio tape will not give you. They are not specific for alpine skiing but that may be a plus for some, who can use it for other activities as well. I have a problem with them coming up as high as they do but it is just that any kind of strong pressure bothers my gut - I simply fold them down a little to take prassure of my gut. Would be nice to see CW make alipine specific tights and bibs for cycling but I do not know if this is what they want to get into. For short: buy them if like idea of comperssion and support fasilitation and do not if you want knee braces. Hope that helps.

Not Thrilled...

I originally purchased the full length tights but they were uncomfortable inside my ski boots so I sent them back and switched to the 3/4 length. The length is appropriate but unfortunately the 3/4 design just doesn't seem to provide anywhere near the same level of knee support (which is what I was looking for to support my knees through a long day of tele turns...). There is also a thick seam that runs up the middle of the pants which I found to be uncomfortable when I tried to use them for running. The tights are very warm and seem to wick moisture well but the lack of a fly is a bit of a pain when skiing.

Overall, I don't think the marginal increase in knee support is worth the discomfort of wearing these all day.

not bad, pretty heavy insulation

Picked up a pair of these hoping that they would work out under a pair of softshells for touring. I spoke with someone at who told me they were very light insulation - which they are not. They have a brushed poly interior, which when paired with the wind resistant material on the front panels makes for a bit of a sauna effect. They are light on the backsides to vent, but I would suggest for heavy duty aerobic exercise to go for the lighter non-insulated pair. In terms of the fit, they fit well and provide a moderate level of compression and provide a bit of knee stability (certainly not comparable to a brace). Overall the construction appears to be of high quality, and the seams are pretty minimal and do not rub.

waist 31" inseam 30" which size do I choose?

Responded on

Just to give you an idea, I am 5'11 and 170lbs. I wear a mediam. My actual inseam is about 31". Sizing depends on your height and weight. You can check out the size scale on the cw-x website if necessary.

What is the level of insulation in these? Would these qualify as light / medium / heavy long underwear? Thanks!

Responded on

I had this + gore tex pro shell (beta ar) and skiied in a 17-30F weather.

Slightly chili on the lift but perfect while skiing.

I tried putting on another merino layer (tight base layer) on top of this but found it uncomfotable - maybe a loose mid layer would've been better

Responded on

These are medium weight. They'd be too heavy under insulated pants in all but the coldest weather.

I was wondering how the 3/4 length fit and feel compared to the full length tights? I have a pair of the full length but the ride down where as my pro shorts do not ride down.

Posted on

Is the length of the insulator tights shorter to accommodate ski boots? I didnt think the support bands would be effective if the tights had to be scrunched and folded at the top of my ski boots - dont want to have to tuck them in my boot if I could help it.

Responded on

Correct, these are 3/4 length to accomodate that option.

Can these articles of clothing be used for wrestlers/grapplers or will the friction during intense cotact destroy the material?

Responded on

Scott. The CW-X Stabilyx 3/4 tight is build extremely well with extra flat seams and very high stitch counts. So the durability under normal use is very good. However in wrestling I know that you are in contact with the mat a lot, and we have not had any specific testing to that extent. But I think the product itself can greatly benefit someone in your sport. I would definitely give them a try. I know we have several Mixed Martial Arts guys on our CW-X team using the product. They had great feedback for us. Good luck.

dont forget that your not allowed to wear anything under your singlet, and this would be rather slipery underneath another layer of spandex
