Ditch post-run chest soreness with CW-X Ultra Support Bra offering, well, the ultimate in bosom support. CW-X developed the five-point star-shaped web of support bands in each side of the bra, holding the breast in place and prohibiting upward or downward bounce. CoolMax and Lycra fabric keep your skin dry and ventilated, with mesh stretch channels under each cup to help facilitate evaporation. Padded shoulder straps distribute and diffuse pressure, so you can head out for miles of running and focus on muscles, not jiggles.

Busty Avid Runner's Secret Weapon!

  • Familiarity:I've put it through the wringer

I am an avid runner and loyal CW-X sports bra wearer. Before finding this bra (and CW-X for that matter), I would wear two or three sports bras at once to achieve a "comfortable" amount of support. This bra makes short sprints and long runs painless. It runs true to size but beware the shoulder straps have metal clasps! I hope this helps!

CW-X Ultra Support Bra - A good buy

    This is a very decent bra. It has three settings in the back and three on each strap. I am a 34C and find that I need the longest setting on the straps and the shortest in the back. Like many bras that don't have underwire but offer significant support, there is that tendency to flatten one out. But still, it is great support and comfortable.

    Love this Bra!

      I love this sports bra. I am relatively well endowed--D cup and this is the first sports bra i have found that i can run in and not feel like i am being smushed. I also haven't had any issues with chafing like I have had with many other sports bras. Great sports bra!

      Excellent Work Out Support

        This is the first bra I have owned that both provided adequate support and efficiently wicks the perspiration away from your body. I've worn this on several grueling hikes and so far have no complaints. I'm not sure if it would provide enough support for running but for anything short of that it would be an excellent choice. The size is 40DD and typically wear a 40DDD for everyday bras. I would definitely recommend this product.

        adjustable straps hurt

          I am a 36 D and this bra does provide great support; however, I needed the adjustable straps to be on the loosest setting and they were uncomfortable. The hook kept digging into my back. If you were to wear them on a tighter setting, you should not have this problem because there is fabric underneath them. I am returning it because I need comfort when running/working out.

            This bra is GREAT

              This bra is GREAT!!! Yes, it's expensive, but if you're a small framed person with a larger chest (34DD), you know that wearing two or three bras sucks. They also last longer than any other bra I've bought so the investment is a good one. I run almost everyday and the support is perfect.

              This Bra Rocks!

                I will never use another bra again. This is perfect for my workouts, it is so comfortable. When they say Ultra Support, they stand behind their word. It has given me the confidence to intensify my workouts with jogging and more intense cardio ! Thanks so much!!!

                Good Support, Lacks in overall appearance

                  I ordered this bra because I was trying to get away from the uniboob look & based on description....thought this might finally be the bra to provide adequate support without the uniboob appearance. Well, it is supportive & comfortable, but doesn't do much for the frontal appearance!

                  Wonderful support, but a pain to put on!

                    I love how much support I get in this bra! The only bra that's come close is the Moving Comfort Maia bra...but this one surpasses it. The only issue I have is how difficult it is to get it on! I bought the right size, (36DD) but when I first tried it on I couldn't do it on my own...I had to get my bf to do it. Since then, it's gotten easier but it's still a pain. However, it's worth a little contorting to not be in pain while working out!

                    Best Sports Bra Ever!

                      I normally wear a 34DD bra - the 34D in this bra fit perfect. I am a runner with natural breasts, so finding this bra was a God send. For the first time ever I feel almost no bounce while running. Not only is this bra supportive but it is comfortable, I can actually breathe while wearing it unlike some other super support bras I have tried.
                      I am buying another one!

                      Spectacular Bra

                        As a 36D, I had gotten used to, but so tired of, mangling myself into and out of 2 sports bras (the old fashioned criss-cross back) for all my workouts, especially on the treadmill. The old criss-cross bras always cut in no matter how lean I got because I needed them tight to get a decent amount of support/control.

                        I decided to splurge on this high-tech CW-X bra and I am SO glad I did.

                        The only bad news is I bought just 1 so I had to alternate this wonderful bra with the old 2-bra-breast-smashing technique. Yes, I am back to buy more CW-X bras!

                        The CW-X bra is wonderful. It is like getting a HUG when you put it on. It provides amazing pain- free support; it is easy to just keep running/working out. This bra is both extremely comfortable and supportive. It’s so comfortable it’s hard to believe it was engineered for amazing support. The engineers behind this bra really did their homework. Each breast gets its own supportive capsule. It's so comfortable I might even start wearing it to work!

                        If you are contemplating this bra but concerned about the price… consider it a present to yourself and an investment in your health. Amazing bra, simply amazing.

                        Worth the money

                          At first I was like, $70 for a bra? But then I figured out how often I work out and how I just cannot take bouncing on the treadmill. This bra is by far the best I have ever used. I used Enell bras but they just compress your chest down. This bra relies on actual support which I really like.

                          The only reason I gave this 4 stars and not 5 is because putting this bra on is a real pain in the butt. I hope they come out with a front zip or front closure bra with this amount of support very, very soon.

                          I am interested in the sports bra but where a 32DD normally - anyone know if it would be to big around my back in the 34? Does it run tight around the back or is there multiple adjustment settings there?

                          Thanks!

                          I'm training for a triathlon and wear a 38D. I'm wondering if anyone has experienced this bra in the water? I'm just worried about chafing while I am on the run portion.

                          Does this bra come in a 34DD?.

                          Does this bra come in 36D? All I see is 40D, 40 is much to big.

                          The manufacturer makes it in 36D, but backcountry.com seems to not have that size in stock at the moment.

                          A Gear Expert (click "chat now") might be able to tell you if they're getting more stock and in what sizes.

                          Is this avaliable in smaller sizes? I am currently a 32D+ according to your size chart. I have a breastfeeding baby, so this bra looked ideal for me. The band sizes currently in stock are all much too big. I enjoy running, but not the bounce on top. Where can I find one of these in my size?

                          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.
