Look great, super tight

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: medium

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.

Unanswered Question

I am 5'4" and about 125 lbs. what size should I order? I would normally order smalls, but the comments make me think medium. thoughts?

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.

will they keep my legs dry snowshoeing or should i go with the insulator endurance pro?

The material is not waterproof or water resistant.

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.

My wife is 5'10" and 130 with pretty muscular butt/hips like most bikers/skiers- should I go with a size large?

I'm 5'11" and 130 with pretty muscular butt/hips, and I took a medium. They look TINY, but the compression felt better in the medium than the large.

Would a large fit me if I wear size 14?

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.

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. :)

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)

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!

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.

    Worth every penny.

      I love these tights! Tried them out this weekend, and they kept me toasty warm. Legs felt great after hiking for 6 hours. Worth every penny. Seriously.
