Not for cycling

    Not a rating/review really, but I wouldn't wear these cycling - the ass will rip on you pretty fast, as the material just doesn't have enough lycra to really survive a bike saddle. The ass of mine is covered in the scars of attempted sewups, and littered with holes.

    It actually works

      These CWX perform as promised. Wear them for running and skiing, both occasions compression support works well to minimize fatigue as possible.

      Great tights for Cold

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

      My first pair of CW-X. I like the compression I get and I use them for runs. They keep me nicely warm down into to 20's and 30's in the dark hours before the sun.

      I'm 5'10 175lbs with decently muscled legs and Med (as suggested) feels decent in compression but the legs feel too long. The slide down off my knees. I've taken to folding the waist which feels better.

      Overall impressed with the quality just might need to size down for myself.

      Nice pair of tights

      • Familiarity: I've used it several times
      • Size Bought: med

      They are warm, they feel good.and they look nice. I run in them and I wear them when I go skiing and so far my legs feel better on the slops. But I am 6' tall about 225 for my weight . So I went for the MED NOT the XL like the sizing chart say. all my others running tights are MED .

      Keeping the legs happy!

      These tights are awesome! Running in Salt Lake during the winter can get a little chilly, and these are the ticket. They have a brushed liner which keeps you warm without over heating. The stabilyx stitching really works. I've put multiple 10+ mile runs in these. Post run soreness and fatigue is next to nothing after wearing these tights. I've been doubling these as an insulation layer for skiing. My only issue is that they are a bit long. I've been rolling the top down and they've been working out perfect.

      My favourite purchase this winter

      • Familiarity: I've put it through the wringer

      • Size Bought: Medium

      I just took up running again after years off due to knee injuries. This gets used a lot. I've used it to run on cold days, as a base layer for skiing and as a recovery tight. I had never heard of CW-X before. This is superior to Under Armor and Nike compression tights which are good in their own right, but don't have the compression or quality support that the Insulator Stabilyx gives. I have them on all the time when I'm hanging out at home. They are simply the most comfortable tights for men. I have a size 32 waist, long lean legs and the medium fits well. I can't say that I fill it out completely in the thigh, knee area. If you have sturdier legs you will get much better compression than I do. A small would have been way too tight and this feels just right. I will be buying more clothes from this company as they are excellent quality and the added support is very useful for someone with knee issues.

      Great Product

      • Size Bought: Small

      Used these on an 8 mile out and back today and they performed beautifully. The size small fits my profile perfectly - my waist is a 30. It was cold, cloudy, and windy today and these were just right as a first layer under my hiking pants. They kept my legs strong on the way up and saved my aging knees on the way down. I wore them for about an hour or so after hiking and they definitely helped my recovery time. I'll likely use them for snowboarding this winter as well. I'm completely satisfied overall!

      Great Product

      These tights are pretty spectacular. I primarily use them for staying warm while ski touring and they have been great for temperature ranges of about 15 - 40 degrees F. The support web feels fantastic when you put them on and although I can't say that they have necessarily helped me go further, they have definitely helped with my recovery on multiple occasions. I prefer to keep them on for several hours after a long tour to help with blood flow and stimulate recovery.

      At a size 32 waist, the size M is perfect, just slightly on the tighter side, which is how I like them. Although I use them mostly for skiing, I have found that they are great for running (they come with a small inner pocket for your house key) as well as for a layer when I am rock climbing in cold temperatures. Definitely the best tights that I have ever owned and will be looking to get more of them!

      Very Attractive

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

      It is a very good looking product and seems to perform very well. I have not used it in subzero temps, but have high hopes for it. It does run a bit small, I have a little trouble getting the cuff on and off. The reason I didn't get the next size up is because I didn't want the cuff to be too loose, but it did just the opposite. Other than that, it fits and looks great, looks like I will get lots of use from it and I get compliments every time I wear the product. I may even get another pair in a different color, though I may go one size up.

      CW-X Insulator Stabilyx Tight - Men's

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

      I am a person that has a hard time staying warm in the cold weather. I bought these tights, in the hopes that they would keep my legs warm when I run in 20 degree weather. I just ran with the wind chill was at 29 degrees, and the front of my leg were very warm. My but was a little cold, but it gets cold no matter what I wear. CW-X makes a well made product that leaves your legs feeling great after a long run. I own several pair of CW-X tights and have never had any problems with them. I have washed them several times and hung up to dry and they look like new. These tights are compression tights, so they fit very tight, but that is what helps your legs feel so good after your run. I am 6” 1” tall and weigh 180 lbs, I bought the large tights, and they fit perfect. I ran again this weekend, 22 degrees with 4 mile an hour wind. I wore a pair of shorts over the tights, and my back side was ok, and the rest of my legs were very comfortable. I will update when I run in the teens.

      do they have a pocket?

      Hey Ben,

      The only pocket these tights feature is a key pocket.

      I'm a Believer

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

      After being recommended to these by a coworker and trying them out for 2 days, I'm a believer. Didn't notice anything special while snowboarding, but I was quite impressed at how good my legs were feeling after each day, especially since they're guaranteed to feel quite sore after the first day of the season. Only complaint is that the waist band is a bit thick, but wasn't really an issue when riding.

      Will definitely be wearing these for every time I go out to ride. Didn't layer anything else over these except my shell pant in mid 30s - low 40s weather, and was perfectly fine. I plan on throwing a loose, lightweight baselayer pants for colder days.

      5' 11" 185 lbs. and 36 in. waist, and Large fit me perfectly fine.

      Cycling? Are these recommended for cycling?

      Best Answer

      You could wear them for cycling but most noteable is there is NO pad or shammy in the seat area. I typically find while riding in cold its a must have or your going to feel that extra hard seat when the temp drops below 45 to 50 degrees. Espcially on the family jewels.

      hi~ am 6'2" 200lbs 36" waist

      what size do u recommend?

      and cw-x is long enough? it reaches ankle?

      Best Answer

      They should have no problem reaching your ankles. As for size, you're nearly on the margin between a Large and and XL according to their sizing guide and the instruction they provide on how the tights should fit (which is tight, but comfortably tight, not constricting to the point of being abusive). That being said, I would go with the Large for sure.


      R u really sure it would reach around my ankle?

      I've heard that it might be short if u r above 6" from many reviews. So am reluctant to buy this tight.

      Besides I don't live in USA so I should be more careful to choose size.

      Anyway thanks for your reply James.

      Good support for the legs.

      I ran two full marathons in two days during the first of December wearing these and my legs felt great. They did the job.

      Can you sleep in these?

      Can you sleep in these?

      Theoretically, you could. HOWEVER, given that they are a winter activity-based tight, I suspect that they would cause you to overheat in your sleep, so I don't know if it would be recommended. *See and4762493's answer to someone's similar question below*

      Best Answer

      Seeing as these tights are compression tights I am going to suggest against sleeping in these as they do not cover the feet as well. What may result is blood pooling in your feet and causing some major medical issues when you take them off. The reason why its not an issue when you are active if because your heart is really pumping and cycling that blood out of your feet.

      +1 here. Compression stuff is only for when you are active.

      It works

      It does block the wind. Very comfortable and supportive. Wear it beloe 50 degrees all the way down to the teens before additing another layer for my tun.


      All around cold gear

      • Familiarity: I've put it through the wringer

      I'm 6' 175 and 34 waist, I have the Larges and they fit perfect. I tried on a set of M and they fit tight, but the crotch would fall down.

      I use these every day for commuting on my bike in the cold weather, I'll wear just these in temps down to 35 degrees then I'll need to put on a softshell pant over it. I also used these multiple times skiing which works great as an underlayer, they are just as warm as my HH warm unders but offer much better support and recovery.

      I also have the CW-X "Pro Tight" and these actually block the wind and are way better for cold weather. I'l l wear these between 50F and below, and the pro tight above 50.

      They are made pretty burly, like the guy below said, they are built to last, and at $125 they are worth every penny.

      Ski and hike

        These are my second pair and they are excellent for skiing and hiking. The first pair I bought 2 years ago and are still holding up after many uses. My legs are noticeably less fatigued when skiing and hiking. They are fairly warm, but when the temperature drops below the teens with bibs on my legs still got cold. Would give 5 stars if a bit warmer, but will buy again.
