Cool, just not for me.

  • Familiarity: I returned this product before using it
  • Fit: True to size
  • Size Bought: Large
  • Height: 5'7"
  • Weight: 150lbs

I listened to the size chart, got what it recommended and while these tights fit, I just didn't feel like they would add anything to my work out, other than the constant worry that you could see through them or that they were falling down. I didn't notice any added support for my knees, so unfortunately, I ended up returning these.

Really liked these tights

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

I really did like these tights. I had recently purchased them, and had the opportunity to wear them for several runs before I tore them up in a fall (they are not rock-proof, lol).

Did the compression seem to help my running? No, I didn't notice any difference in how my legs felt. However, one benefit of the compression tights is that it keeps the booty under control. Yes, it was like a running sports-butt-bra. And it was marvelous.

Would I recommend these? That depends: are you looking for an athletic advantage? Probably not. Are you looking to wear something flattering that won't make you feel like your rear is going to knock out innocent bystanders? Yes, buy the tights.


    I've never worn compression tights. I finally got the right pair of running shoes this year but at 52 with several joint and stride challenges, I was sure I would be permanently limited to half or 1-mile distances--shin splints were my biggest curse, along with Achilles issues. In two weeks, I've moved from 1.5 miles to 5 miles, injury free, no shin splints, no Achilles troubles, not a single grumbling joint! First time hitting 5 miles in 19 years!!!! Thank you Stabilyx, for keeping all my wobbly joints--rebuilt knee, back and aging hips all aligned and happy! I won't ever rack up the miles on my frame, but it had definitely changed my point of reference--I'm not as limited as I thought I was!

    PS...only complaint is the familiar one: it slides down from the waist. Tying it tighter is not an ideal solution. They would fit better if they were either less stretchy or were cut more snug in the last 5 inches to the waistband.

    Great for Winter Running

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    I gave these as a gift and she loves them! They do stretch out a bit over time, but not in a bad way. They are still really compressiony and tight fitting. Even with the tight fit they aren't overly tight or restricting and the fabric keeps you cool.

    I love them

    • Familiarity: I've put it through the wringer

    I now own 3 pair of CW-X compression deals. I have the shorts, the capris, and now these. These are great for winter running, and the support they give makes a Huge difference in recover from longer runs. Just remember that these are the lighter side of support for compression.

    Don't be scared

      I'm 5'5", 165lbs and bought the medium, so I was initially intimidated by the fit of these tights. However, when I realized it was like putting on stockings they were perfect. "Don't be scared ladies"... It's like putting on your favorite skinny jeans and realizing hey I can really fit these.

      No More Muscle & Joint Pain!

      • Familiarity: I've used it several times

      I have had these Compression pants for almost a month now and I fell in love with them from day one. I'm 5'7, 140lbs and athletically built. I ordered a size small and was very concerned when I opened the package. At first glance they look like a pair of skinny pants my 10 year old niece would wear! But once I pulled them on (not as difficult as I thought it would be) they fit like a dream! These pants are an enormous help in muscle & joint control. Before using these I had pain in my knees and my quads, hamstrings and calfs would get tired and sore fairly quickly. I use these for every run, plyometric and HIIT training. I no longer have an inner battle of feeling like I have to stop my training because of pain & fatigue in my legs while the rest of me still has the stamina to keep going! They also keep my body temperature perfectly regulated while wicking moisture away. All in all, I couldn't give these a higher recommendation!

      Handles the jelly

      • Familiarity: I've used it several times

      Being bootylicious has no place in running, well not when it moves. Love these pants because they hold everything in place and keep my lower body from fatigue due to unnecessary movement. My posture/form remains where it should. These are the Spanx of running tights.

      They are compression tights, after all.

        I've never worn compression tights until this purchase. To be honest, it took an act of god (perhaps the running god?) to get into them. There are instructions on the package stating how to put them on, but quite frankly, the scene in the house was like something out of a Saturday Night Live skit. Anyway, I am 5'2", 125 lbs, cycled for years, enjoyed microbrews for years (with no cycling), and consequently have fairly thick legs. Based on the opinions here, I bought a medium and am happy that I did. They were a tad binding around the back of the knees, but I have to admit, they felt good while running and my knees felt better when done. They were a little long for me, but hobbitses aren't known for their fairy-like legs. I'll defintely be purchasing another pair.

        Love em

          I was skeptical at first, but am really pleased with how these tights feel and fit and perform. The sizing chart is perfect, I got the XS and I am 5'1 and 118lbs. They even look fantastic. The price was really good too. You will not be disappointed.

          Not all of their products are created equal

            I have previously purchased XW-X Insulator Expert tights and they were phenomenal! I decided to buy the Performx and check it out. I am 5'1" and XS on the Insulator fit perfectly, so I ordered the same size for the Performx. Unfortunately, when they arrived, I could barely pull them past my thighs. They were a lot smaller!

            I'd highly recommend you try them on at a sports store before purchasing online!


              I should have gotten a size bigger. I'm 5'9" and have a large athletic build (i'm a rower). I ordered a Large. I got these for running and rowing in cold weather. Although the fact they are so tight is very flattering, within a couple months the crotch of my tights busted.They are also short, inches above the ankle short. I've been compromising for months now but have recently decided to see if CW-X will take them back under warranty... I want a new pair though, they're awesome!

              Rowers of the world unite!! But anyways your review caught my eye because I'd be using them for the same exact purposes. I am a bit over 6 foot, and seeing that you're 5'9" I'm inclined to say there isn't a chance they'd fit me. Would you be inclined to agree? I really want these snazzy tights, but just need a bit of affirmation I guess...

              be careful with the size

                I am 5.8 and 130 pounds. According to the site's sizing I should have bought size S, whcih I bought. Pants are really really small and short. I am going to buy size M, hope it will be fine.

                Just to give you some perspective, I am 5'2" and about 115lbs. I am small-framed and wear the CW-X Performx Tighst in size xs. The tights fit me snugly, but not uncomfortably. The length is maybe a half-inch to an inch longer than I need, but it doesn't bother me. I recently wore them for a 10K and I felt they gave me good support, yet did not restrict my movements in any way. Hope this helps. :-)

                I am 5'2" and about 110lbs...will the XS fit me?

                Hey there!
                I am 5'3" and 120 lbs, there is no way the XS would have fit me, but it might work for you. The size small fits me perfectly. They are a bit difficult to get on, but that is how these tights are meant to perform.

                I am 5'7" and about 135 lbs. Would the medium work for me? I don't want the crotch to ride down as I am running, but I am thinking the small may be a bit too small. Also, what is the inseam for these? Thanks!

                I am fairly new at running (since April) and I am up to 8 miles right now. By mile 4 my knees start to sting and don't stop until 1 hour after I am done. Right below my knee caps the skin has a puffy look. I am wondering if these tights will give me the support I need for my knees or if I should look towards something like the stabilyx tight?

                Hey Carey,

                I'm very sorry to hear about that pain you've been in. I do feel that the CW-X Stabilyx Tight is a lot better choice for you though. These running tights also integrate CW-X's Conditioning Web, designed to help muscles and ligaments bond together to stabilize the knee joint.

                I am 5'5" and 117 pounds. I have the 3/4 length CWX and ordered a small in those but seeing other peoples comments do you think I should order small in these too or XS.. XS scares me!

                Hi. I have 3 questions:
                1. I'm have run 4 half marathons this year with some IT-band issues and am training for my first full marathon, hoping to prevent injury. I am trying to decide which tights are the best for IT-Band issues- Performx, Stabilyx, or expert?
                2. Also wondering what size to order...I am 5'6" and 127 lbs, with most of my height in my torso. I usually order a size medium in tights because of muscular thighs, but according to this I am a size S. Just want to make sure I can get into them :)
                3. My marathon is in Oklahoma in late november, usually in the 30-40 degree temps. Has anyone run in the insulators? Didn't know if the insulator capris would be too warm in that weather.
                Thanks all!

                these might help your ITB issues, but working on form and stretching/massage will help more. Also training too hard too fast can cause ITB pain. Talk to a sports medicine doctor- don't rely on this product to solve injury problems. Good Luck on your marathon!

I'm wondering if and which model of these tights would be helpful. I'm 5'4' and 130lbs. Thank you.

Any advice on which CWx tight is better would be appreciated. Thanks

                Hi Mary Carol- Size XS is what you need. They stretch very well and will give you the right fit. If you go up a size to Small, they will most likely be slightly loose on you which defeats the purpose of the support web system. Get the XS size. You will love them.

                Hi, I'm an avid snowboarder and was looking to buy this as my first layer. I'm going to be wearing Goretex burton pants over them. And wondered if they would be good as 1st layer, my main concern is keeping me warm and wicking away the sweat whilst helping my muscles as I ride.

                Just wondering which style and size would be best. Having trouble with IT band and knees. I am 6ft and 138 pounds. Thanks for your help.

                Lynn- You've picked the right tight for IT support. Since you are tall and 138lbs, you are really between two sizes. Your height calls for a Large, but if your weight points to Medium. If your height is mostly in your legs, then I would say you need a size large. Especially if you have strong, athletic legs. if your height is mostly in your upper body and your legs are skinny, I would try the medium. You may have a small gap between the bottom of the tight and your ankle, but that's ok. The tights should feel comfortable and fit like second skin. Not too tight and definitely not too loose. You know the tight is too loose on your legs if you see major wrinkles in the fabric and it's bunching up. I hope you enjoy the tights.

                I'm seriously thinking about getting a pair (or two) of CW-X tights, but don't quite know what size to order. I'm 176cm tall and weigh 75-76 kg. So, I fall into the grey area between the M and the L on the CW-X sizing chart. I carry my weight more in the thighs and hips and than in the upper body so I'm leaning toward the L. Can anyone confirm that choice?

                Hi There. If you are in between sizes, I would go up to the larger size. Especially if you carry the weight in the tighs and hips. The tights should sit comfortably on your body and feel like a second skin. Not extremely tight. Good luck, I hope you enjoy the CW-X performx tight. It's a great product.

                I have checked the size charts. I am a 5'10" female, 180lb, with large legs (I lost 100 lbs, and my legs are still large with excess/baggy skin). Per the size chart, i would fit in the women's Large. however I often find that women's sizes just don't fit well on my frame. Womens clothes, even "tall" sizes tend to be too short, and the rise (crotch to waist) also tends to be too short.
                I am thinking of getting the men's large or x-large.
                My question is how does the cut of the men's tights compare to the cut of the womens? are they basically the same, but men's have longer inseam? (great!) or do men's have even a shorter rise (crotch to waist)?
                Thank you for any insight on the clothing design comparison between the men's and women's versions of these tights.

                Hi There. That's a tough one. CW-X products are anatomically designed to specifically fit Men's or Women's frames. However at this time CW-X is not making a Women's XL which is probably the size that you need. My wife is 5'11 and she wears our Men's Large size. The CW-X Performx tight would work best for you because it is not as essential to get the knee cap in the right place like it is in The Stabilyx Tight for example. In the performx tight, you will get good support and targeted compression on the sides of the knees, the quads, hips, and IT band. They are great tights. I would try the men's Large and see how they feel.
