Kathryn. Small is the right size for you. Don't worry about the bunching up behind the knee. As long as the tights are comfortable on your waist and around your quads, hips, etc you are fine. and yes, the flat internal seams do leave a little indentation in your legs. Just shows you the support/compression is working and you have a proper fit.

Kevin- I would definitely go with the Insulator Stabilyx tight. The material itself is a Nanotech fabric that regulates heat close to your skin depending on temperature. For example, if you are out in the AM for a run and it's 30 degrees outside, the material will form a thermal layer and prevent heat from escaping until you reach about 78 degrees at your skin surface. This is the optimal temp for muscle performance. Then the material will stat releasing heat and keeping you at that level point. So the tights don't feel hot. Also, there is a wind blocking material on the quads which is great if the cold PA winds pick. I think you will be really pleased with the Insulator Stabilyx. Plus if you ski, you can use it as a base layer for skiing. I would go with a medium for the size. Good luck.

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.

Hi Emma-

The CW-X Ventilator tights were specifically designed for warmer weather. CW-X used Thermal imaging studies to see what parts of the leg get hottest during running in warmer weather. The hottest spots are around the quad because it is exerting a lot of energy during the run, and the calf muscle because it is behind the leg and does not get any airflow. So CW-X put vented mesh in those two areas of the leg in the Ventilator tight. I can tell you that by just cooling those two areas and allowing more airflow in the quad and calf, the entire leg feel more comfortable somehow. Since you get the most support out of the full length tights, I would recommend the Ventilator tight for warm weather. Good luck!

Hi There. The 3/4 Stabilyx tight does not offer any calves support. You will have to go to the Full length version for that. The patented CW-X support web is based on Kinesio Taping techniques that trainers use to support specific muscles, create better circulation, muscle efficiency, etc. The calves support in the full length CW-X tights is very good and creates all the benefits of Kineseo taping but it's built into the garment. As Greg mentioned above, the other option is to wear the CW-X Compression support sock with a 3/4 Stabilyx Tight. I usually pull my socks just over the botom of the 3/4 tights to keep both the sock and the tight in place and aligned properly. Backcountry does not have the socks in stock yet, but you can find them online or go though the CW-X website. Good luck.

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.

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.

Hi There. Good question. You may be able to shrink the Stabilyx Tight Large down a little bit in the dryer, but not much. Keep in mind that the tights need to feel comfortable, like a second skin. Not too tight. Just having slight support and pressure in the support web will give you the benefits of the support tights. However, if the fabric is bunching up and you see wrinkles around thee quad or knee area, then the size is too large. Based on your height and weight, I would recommend a size large. If you weighed less than 170lbs and had skinny quads like me, I would recommend a Medium. Hope this info helps you.

If you are in between sizes, you should size up. What is your height and weight (yes I know it's a personal question....)

Hi There. Fit is a personal preference thing, so it's tough to say if something works for one person, if it will work for another. CW-X Pro shorts are worn by Ultra marathon runners and adventure racers all across the country with great success, while other people feel chaffing in the crotch seam after an afternoon run. It's very strange. I would say that the benefits you get from wearing a support short like the Pro short are especially useful for longer runs. The patented muscle support system allows the muscles to be more efficient during movement and minimizes fatigue over time bacause your muscles don't have to work as hard over time. The key is getting the right fit. I am 5'11 and 168lbs. I wear a medium short and tight. Anyone over 6'1 or over 175 lbs should be in a large. The shorts fit snug but not too tight. They feel very supportive and I have never had any chafing issues in the crotch seam. Sometimes wearing a thin sport brief under the tights or shorts helps also. Good luck!

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.

I would recommend a Medium. I am 5'11 and 168lbs. I wear a medium. If you were over 6 foot and over 175, I would recommend a large.

Hi There. For warmer climates I would consider the CW-X Ventilator Tight- Specifically designed for warm climates) or the CW-X 3/4 Stabilyx Tight. The correct fit is important. The tights should feel like a second skin. Not too tight but definitely not too loose. If they are too loose, the support structure will not work properly. You will know if the tight is too big if the fabric bunches up and has major wrinkles around the knee and the quad area.

Hi There. I think I can answer your question. There is no difference in the type of support you will get between the CW-X Stabilyx tight and the CW-X Insulator Stabilyx tight. The main difference is in the fabric. The non insulated Stabilyx tight is constructed of Coolmax which is a great overall athletic material that breathes and wicks away moisture. The Insulator version is made from a proprietary nano-tech Temperature regulating material called Autosensor. This material feels slightly thicker than coolmax and has a brushed micro fleece feet on the inside. The Autosensor material is designed to sense the temperature outside vs your skin temperature. If your skin temperature is cold, the material forms a thermal barrier and traps heat while you warm up. Once the temp reaches about 81 degree F the material starts releasing heat keeping you at an optimal temperature during exercise. The other main difference in the tights is that the Insulator Stabilyx Tight has wind blocking material on the quads. Great for colder or more windy days. Bottom line is that now we are in October, the Insulated Stabilyx Tight may offer you enough temperature flexibility but you will be able to use it once the temps get cold. Also it's a great underlayer for Snowsports like Skiing, snowshoeing, Tele, etc. Hope this helps.

Hi There. CW-X products are designed to hold up to normal use as either an outerlayer or a baselayer. All I can tell you is that I have been using the same pair of insulated tights for my third season already and the wear is minimal. CW-X construction is very good. and if you ever have any problems CW-X has a one year manufacturer's warranty. Hope this helps.

HI Lauren- I would recommend the CW-X Ultra Support bra for you. It is fully adjustable in the band and in the shoulders, has padded shoulder straps and is designed to properly support a DD cup. You can find it on Backcountry.com It's a great Sports Bra for running and all around high impact activities.

Hi There. CW-X makes three styles in 40 DD. The CW-X Xtra Support Bra, CW-X Xtra Support Zip Bra and CW-X Ultra Support bra. YOu can find all three of these on Backcountry.com

Hi Dawn-

I have to tell you that since the CW-X Ultra Support Bra came out this past spring, the response from larger cup women has been phenomenal. Look for this product on Backcountry. I know they have most sizes covered. The Ultra Support bra ranges from a 34 to a 42 Band in B/C, D, and DD cups.

Hi Renata-

Size S on The CW-X Firm Support Bra was an old sizing designation for the sport bra. Small is really a 32B/C. Hope that helps.

JoAnn- Just saw your question..... The CW-X Expert shorts do not have a set inseam. Because this is a stretch product, the short is designed to position itself differently depending on the exact body type and shape you have. The short is designed to be longer than traditional shorts by a little bit because it is designed to support the quad. So typically the short will stop right above your knee area on the quad. Hope that helps.

Debbie- Just saw your question now. CW-X Tights are not specifically sold as a medical grade compression product. However, the patented CW-X support Web on the tights does offer a targeted support and compression benefit. To answer your question directly, the areas of the tight that do not have the Support web have a 15-20 mmHg rating. The support web has a 20-25 mmHg rating. so what you get is a more targeted type of support and compression where the muscles are rather than overall compression of the entire leg. This is key in athletics where you want the support and compression in the key muscle areas but not all around. Hope this helps you. We have had many customers who greatly benefit from the design and function of the CW-X Tights.

Mike- No Chmois in the Pro shorts. The only Chamois product we have is the Triathlon Short with a fleece Chamois.

Hi Joyce. If you haven't done so already, I would get a size Med. They need to fit like a second skin. Not too tight and definitely not too loose. You are right in between our size S and M. In cases like this, we usually size up. You may have some extra length on your ankle area, but as long as the knee is positioned properly and the waist sits in the right place, you will be fine.

Hi There- Here is my response to another customer..... I would go with the Stabilyx Tight for overall performance.

Hello there. Very good question. Did you use our tights finder on CW-X.com? and you did not get the answers you were looking for? Anyhow, the CW-X Stabilyx tight is our best Stability tight that supports Knees, Lower back, Hips, and Quads and is best for high impact activities that have a lot of movement from side to side. For example Trail running, Skiing, Hiking, etc. The Pro tight works best for constant motion activities that are not as high impact. For example Road running, Nordic skiing, etc. The pro tight does not have the knee support like in the Stabilyx, but it does offer more Hamstring support. Versatx is a softer support system that only focuses on Hips and lower abs. The performx tight is new and focuses on support through the IT band specifically. it only offers medial and lateral knee support (just on the sides of the knee). The Stabilyx tight is the best all around tight if you plan to use it for a variety of activities as a base layer or an outer layer. Hope this helps answer your question.

Tina- Yes the CW-X Ultra Support Bra does come in a 36 D. I see that Backcountry is low on sizes, etc. You should contact a gear expert who can place a special order for you from CW-X and get you the right size.

Hi There- Yes The CW-X Ultra Support Bra does come in a 34DD in white color only. You will need to special order it through one of the Gear experts at Backcountry. We also do a 34B/C, and a 34D.

Hi Emily- The CW-X Ultra Sport Bra is a great bra. We just recently added a 34 band in B/C, D, or DD cups (white color only). Feedback from women is that our bras fit one band size smaller than a traditional lingerie bra. so if you are wearing a 32D in a regular bra, the 34D or 34 DD would work fine for you. I see that Backcountry doesn't have the 34D or 34DD in stock, but I'm sure if you conact a gear expert, they could probably have one special ordered for you.

Bob- The CW-X VErsatx Web Top that you would need is an XL. It needs to fit like a second skin and not be too tight. I think if you got the large, it would be a bit snug.
