Warm support

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size
  • Height: 5'10"
  • Weight: 160lbs

As others have noted these are definitely a 'next to skin' fit, which is exactly how they are supposed to fit being a compression tight. The compression fit and bands running through these offer awesome support to keep you going longer and shorten recovery time. They offer great stability for knees as well. These are the insulated version which will offer more warmth which is awesome for getting outside for a run during the winter here in Utah or other cold climates, and the windproof front panels are awesome for those cold windy days. Fits true to size, the recipient normally wears a medium in bottoms and these fit perfect in the same size.

Tight Tights

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: small
  • Height: 5'4"
  • Weight: 135lbs

Admittedly, getting them on can feel like battling a wet suit, but that doesn't matter because once you get them on you won't ever want to take them off. These are tight without constricting, supportive without compromising flexibility, and warm without getting swampy. I love these tights and will be skiing in them every day this season!

Look great, super tight

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: medium
  • Height: 5'5"
  • Weight: 135lbs

Love the look of these, unfortunately they run smaller than I expected. I'm keeping them but will only use them on long runs/days when I'm geared up for very snug pants.

CW-X Insulator Stabilyx Tight

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

These are my preferred baselayer when skiing. I love the added support of the stability bands. They are too warm for a spring day, but for the rest of the season the weight of these is perfect.

Best Fit and Provides Support

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

Love the fit. I'm 5'1" and 108lbs. Bought Small in the Insulator (due to thicker fabric) and XS in the regular Stabilyx Capri. The Insulator keeps me warm in 20°F weather. Legs were never cold. Training for a marathon, started getting runners knee so I thought that I would try these out. Great support, now can run much longer without the after pain. Tried Opedix...TERRIBLE FIT.

Not as expected

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

I own 2 pairs of the Stabliyx Tights and 1 of the Endurance Generator Tights. All three products are great, so I bought this pair so that I could run in the winter months with more warmth than the other versions I already own. I bought the same size as my other versions-medium (I am 5'7", 140 lbs) and with the Insulator versions I could barely get them on. Once I was able to finally get them on (took a bit), they were really uncomfortably tight and felt wrong. I get that the material is thicker than the regular version but you would think CW-X would adjust the size accordingly to account for it- which makes me think that I may have a defective pair (product was shipped w/o regular packaging). As a result I am returning to Backcountry. Totally bummed as Backcountry had them at a great price and I really love this brand.

Love these tights

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

I've been running in conditions ranging from 15-35 degrees F and have not been cold at all. They're very tight, they're basically compression pants, but very comfortable at the same time. I'm 5'4", 130lb and I got a size M. They fit great. They have a pretty tight waistband and it's an effort to get them on and off but it's worth it as they don't slide down when you're running. I don't know if it's a placebo effect but my IT band has hurt less since I started wearing these.

Great winter tight

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

These are great, they have a lot of compression. The wind front works well, though the backs of my legs get chilly in sub 20�F temps. Would be excellent for skate skiing as well as running, I think. The size medium is right for 135lbs/5'6".

Perfect Tights for Running a Road Race

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

These are true compression tights and as such fit much snugger than a regular running tight. I contacted the company directly prior to purchasing to double-check their sizing chart. I went by the CW-X chart and their reps' recommendation. These tights come with special directions describing how to put them on -- follow it. They are more like womens nylons in this way and should be positioned properly and really snug for the stability fabric to do its job. I've been training in these on my runs (3-10 miles) in the New England winter (6F-36F degrees) and they keep me warm enough for this type of activity and do a decent job of hampering the wind. I recently had a small pull in my quad muscle days before a race -- the tights helped significantly in supporting my leg for the race (I was even able to set a PR!). Tights are well made and look good on. I'm saving up for another pair and will be getting their compression shorts for summer running as well.

CW-X Insulator Stabilyx Tight - Women's

  • Familiarity: I've used it once or twice and have initial impressions

i bought the cw-x insulator stabilyx tights and used it for this past weekend race - ozark endurance run in the state of MO. it really works for me! compare this product with the other normal stabilyx tights, this tights is slightly more heavy/thicker but it is very breathable. it shields me from feeling cold (the normal one would still do the job but you probably could feel a little wind still). totally recommended it. :)

Totally recommended!!!

    This is the best running gear purchase I have ever made. Great warmth with no extra weight. Seams are very comfortable, not always the case with a compression tight. I wear these not only for running (October thru March), but as a base layer for cross country and downhill skiing, snowshoeing and hiking. I have had these pants now for 2 years now, wear them multiple times per week and am not fussy about laundering them in a particular fashion and they are still like brand new!!! This is the first time I have ever written a review for anything because I am that impressed.

    i totally agreed with you! have you tried their top yet? i prefer to run in loose top but i was feeling very cold in the high 30s and low 40s. i'm wondering if i should invest in it. tough decision. probably need to check out for reviews from others.

    Sizing tip

      Theses CW-X Insulator Stabilyx Tights are great. I think that the sizing is pretty accurate unless you have skinny chicken legs like me. I had to return my tights for a smaller size in order to get that tight, stabilizing fit that these tights were made for.

      Pearl Izumi is the way to go.

        I purchased a pair of these pants and a pair of Pearl Izumi Elite running/cycling tights and the Peal Izumi's won out. The CW-X tights seem slightly less warm and much less comfortable and stylish.

        great winter tights

          These are really super! Wish I had them sooner, as they are terrific for winter sports. I am using them for x-c skiing this year. The tight fit fools you; they are extremely comfortable.


            my girlfriend is 5'4" 125ish and wears a size small in these pants. yes they are tight but that is how they should fit. she has worn them in temps around 30 degrees and was completely comfortable. a great pant and she can definately tell the difference between these and regular spandex. they are expensive, but well worth it to be able to run in the winter and be comfortable.

            I love it.

              I had a minor injured on my right knee from downhill skiing last year. It left me slightly pain after that when I downhill skiing or hiking down the mountains. It was amazing that the pain on my right knee was gone when I wore it the first time for downhill skiing this year. I would recommend this tight for any sport activities, just make sure the size fit you well.

              I'll by more of these!

                I bought these tights to wear as a base layer for skiing in cold weather. Found that they are an excellent choice not only when it is cold, but in any weather other than very warm spring conditions. Fit was snug as described, but not at all uncomfortable. And I am sold on the muscle stabilizing aspects of these tights! I have pretty severe arthritis in one of my knees and was able to ski aggressively for six consecutive days until the lifts closed!

                Great tights

                  I found these to be very comfortable. I ordered a size larger, as I am tall (5'9", 150#) and as with panty hose, find that most stretchy items fit better up one size. The large fit well, a bit like putting pantyhose on, scrunch them up and start at the bottom, adjust as you go. Wore them under Spyder Bamboo insulated pants skiing in Colorado temps ranged from about 15 - 55 and I was comfortable every day, no binding. The waist is a bit big, but the drawstring helps keep the pants up. Didn't tuck my slippery base layer top in the second day which seemed to help keep the pants up a little higher. Very happy with them.

                  Great for Skiing

                    I bought these on recommendation from a friend - so glad I did. These tights are the perfect addition to my ski gear. I wear them under my Gore-tex ski pants. They keep my knees supported and offer warmth without being hot. I find my legs are less fatigued at the end of a long ski day. One minor complaint is that they tend to drift down a bit in the crotch. Usually, by the time I'm ready for a pit stop, it's time to hike up the tights an inch...overall, not a big deal. I have long legs, and not much junk in the trunk, so I'll blame my anatomy and not the tights. The other bonus is that the tights are easy to wash. They quickly air dry overnight, so they're ready for the next day's skiing. Plan to use these for my cold weather runs as well. Great product!

                    I'm 5'1" and about 120 lbs with 34" hips and muscular legs. Should I go with an xsmall or a small? I normally wear 2XU compression tights and calf sleeves, so I'm unsure as to what size I should order in these. Thanks!

                    I'm 5 ' 1" , but weigh about 130 and have similar build (muscular legs). I purchased these in a small and they are fine ,but a bit more snug than I think they should be. I would have prefered a medium, but since I found them at half price at TJMaxx I wasn't going to complain. (they had a large and they fit fine,but I think I needed more compressin. I think the small would be perfect for you.

                    Best Answer

                    Yes they will. These tights are the Spanx of running tights. You have to do the fat lady dance to get them on but once on they are not constricting, pinching or uncomfortable. I own 3 different pairs of CX-W tights and don't race in anything but them.

                    I'm 5'4 and about 110lbs, I really want to order these tights but I'm not sure if I should order the xs or small, Any advice?

                    Best Answer

                    I am 5'0", 103 lbs, and wear the XS's. I have muscular thighs, and the XS's fit perfectly. If you are +4", I would suggest trying the size Smalls first (to get a little extra length), and will allow you to exchange easily if you decide to downsize.

                    I'm, sorry for the stupid question, but...

                    I'm, sorry for the stupid question, but can I wear these tights as an outer wear in the mountain? Or they are more like an advanced thermal basic wear? I want to try hiking during the winter and I'm searching for an elastic tights/leggings that I can wear, because I like feeling free while walking and the winter pants can't provide me with this comfort.

                    i'm not sure what do you mean outer wear - very sorry because i don't have winter here in singapore. if you wonder can you wear something inside this tights (means this tights is worn on the outside), then i think the answer maybe no - to check with CW-X to confirm. but i think you can wear something over this tights. :)

                    Hello Elena, you would not want to wear anything under these tights, as they are tight, and having them over your direct skin is how they do their job of maximum insulation. It is no problem to layer over the tights, however. They make a great 'baselayer' under ski pants, and will keep you nice and warm without adding bulk underneath a pair of ski pants. They are also great for running in, without needing to put anything additional over them.

                    I'm 5'2" 125 pounds and I got the small,...

                    I'm 5'2" 125 pounds and I got the small, but when I tried them out a couple of times, I kept feeling like the back of my knees were being pinched. I know the size chart suggests sm for my height/weight, but would medium be a better fit? All the "bands" on the tights were fitted properly around my knees etc, but the back of my knees/IT bands were sore after wearing them.

                    These fight TIGHT. I am just about your size - 5'2", 120 - and have a full seat & hips. I went with medium and while that's even a snug fit, I can tell a large wouldn't be supportive enough.

                    I can't find info regarding the temp ranges...

                    I can't find info regarding the temp ranges for the insulator tights vs the "regular" (i.e. non-ventilator) tights. What would you recommend???

                    i think insulator means it keeps you warm? while ventilator means keep you cool in the summer? i wore it in the ozark endurance run just few days back and the evening temperature was about 40s low to 30s high and throughout, i never feel cold in my lower body. now, i'm thinking if i should invest one in the upper body.

                    I've worn both, and found that this insulator version is by far the best for cold weather and winds. I've done several runs in 25-30 degrees F with medium winds and these have been perfect (no cold red thighs post run).

                    What temperature range do you think these...

                    What temperature range do you think these tights are best for - assuming I'm running aerobically (Zone 2-3)

                    Best Answer

                    Hello There. The CW-X Insulator tights do well at temperatures below about 40 degrees. Everyone deals with cold differently, but the tights can be used in below freezing temps, as long as the wind is not super bad. There is a wind blocking panel on the quads which does a great job blocking the wind. The rest of the fabric on these tights is designed to adjust how much heat is real eased based on use. So for example if you are just starting out and your body temp is cold, the tights will trap your body heat until your body warms up to around 80 degrees. This is optimum operating body temp for athletics. Once the threshold is reached, the tight releases heat, keeping you at a steady temp. This minimizes the hot and sweaty vs wet/cold situations. Good luck!
