best bra i have purchased. no bouncing around and no uniboob. Great support but tight like it should be.

Pros: + Keeps C cup boobs from bouncing all around during runs. + Consistent support even on long runs (1 hour+). + Easy on/off - not SO tight that I strangle myself trying to pull it over my head.
Cons: - Kind of leaves your boobs droopy looking. Perhaps that's just how they are these days?

its great good support but hard to get into and out of when your hot and sweaty from running - it would be perfect if there were hooks instead of over the head.

I just ran around playing ultimate frisbee in this bra for 10 hrs, and it did such a good job of supporting me that I forgot I meant to evaluate it for a review. Basically, I didn't even notice it was there. The only reason I would give it a 4/5 is that its cousin, the ventilator, is my favorite because it kept me cooler in the gym on the treadmill. I'm a 34B, and i wore the size M, B/C.

I wouldn't go as far as saying this bar is a miracle or that it's comfortable enough to wear all day, but it's definitely a solid bra that I'm very happy with. I'm a 34C, and it completely eliminates bouncing without making your boobs feel smushed. It looks good enough to wear on its own, and it also works well worn under a shirt -- much less uniboob than any other bra I've ever tried. It's an all around decent bra.

I was surprised at how lightweight this bra is. I love it for backcountry skiing - since it's so lightweight my sweat dries way faster than a normal bra, which is super important being out in the snowy cold! I wore this running and did not think the support compared to my trusty old Brooks smash 'em bra. Too much bouncing. I am a HUGE fan of the CW-X running tights - and when I saw that they made a bra, I had pretty high expectations. The picture of the bra looks as if it has the same type of support bands as the tights do, but they are the not the same at all. So, I wouldn't recommend this bra for anything high impact, but it is great for skiing, hiking, and climbing.

sizing not the best when you are a D cup

The bra gave great support. A little snug underneath for all-day wear. I ordered a medium and wear a 34 C bra. I used it for trail riding in the high country and wore it all day. Definitely gave me the support I needed for horseback trail riding, but I was also glad to take it off at the end of the day.

This sports bra is great! Not only does it prevent bounce without compression, b/c of the material I do not get that gross "get this sweaty bra off of me this second" feeling after my runs. I was one to wear two sports bras for the support b/c I always had a larger chest and hated the bouncing. I no longer have to do that because of the unique support web that encapsulates each breast nearly eliminating bounce all together. I will never wear another sports bra again. Thank you CW-X!

Love this bra, holds me tight and although there's a little bouncing, there's no pain and total comfort. The fabric is great and holds up really well. I highly recommend it.

Definitely the best sports bra I've ever worn! It does a great job during any activity, even running! It doesn't fit like a bra--I barely even notice the support it's giving. It's not like a typical sports bra that crushes everything into submission.

Maybe its just that i've never had a 'real' sportsbra until noww, but this is deffinately the one to go with if you've been looking for good support, comfort and looks. This has it all. I'm 5'4' 38C and the large fits nicely! I will definately look into other CW-x Products. Made of a nice material, feels like quality, washes well. I'm an instant fan of this product!

I exchanged this CW-X Sport Bra for the Xtra Support Zip Bra. I couldn't get the one without the zipper over my shoulders and felt like that if I kept it, I would someday dislocate my shoulders getting it on and off. I love the Sport Bra with the zipper.

It is very supportive and fits well, but when I've worn it all day for skiing, the mesh portion irritates my skin. But it's great for shorter things like trips to the gym, etc.

Finally, a sports bra that lives up to its lofty promises!! This bra snugly encapsulates each breast so you feel supported and secure, without feeling mashed. It's extremely comfortable to wear... and as an added bonus, it's cute and actually flattering. I won't wear anything else when I go out for my long runs.

This is the best sports bra I have found so far. Comfortable, supportive (C cup), and attractive. I am comfortable wearing it by itself in the warmer months. Works well for both short and long runs.

This is by far the best sports bra I have ever had, and I've tried them all. I recently ran a local marathon and experienced no discomfort at all...a first for me! No bouncing, no chafing, no sore shoulders. I don't think I could ever do another long run without wearing it.

I am used to wearing two "mash 'em" bras when I run, so I don't bounce. This one has this high tech support system in each cup, and while it felt really good, I didn't expect too much. Wow! What a difference! I won't wear anything else now when I work out. I also love the great material, it really keep the sweat away. Worth every $$.

I just purchased my CW-X bra; I wanted to see if it was as great as the ad claimed. I am about a 38-C and was tired of having to wear 2 bras for support while running. It's worked out great, it doesn't eliminate the bounce, but gives enough support. It's light and comfy. I think I should buy 1 more. A+

I'm still searching for a substitute for the Hot Chillys System 2 & 3 bras that I loved. This isn't it. I'm a 34C and did not find it as supportive for hi-impact aerobics as the other reviewers. It also lacks separation and results in a uni-boob look.

I bought this bra to wear while hiking during a trip to Yosemite and the Grand Canyon. It felt a little compressing when I first put it on, but after wearing it for a while it molded nicely to my body. It did a good job of wicking away the sweat. All in all, I am very happy with this bra.

I'm pretty small and didn't think that I needed anything other than a normal sports bra to get me through activities. I never experience bouncing or shoulder pain with any type of sports bra. I just experience two big things, a flat chest and a sweaty sports bra. As a woman, I still want to feel like I have some womanly shape (like boobs) when I'm working out. Also with normal cotton sports bra (the only kinds I ever had bought) I would sweat and they would get cold and yucky. I got this bra as a gift and will NEVER put those gross cotton ones back on! I couldn't believe that a) I filled out the cups just perfectly, b) it's super comfortable, c) supports where I didn't know I needed it, d) didn't get wet from sweat, wicked perfectly in the right spots, and e) still made me look like a woman. I could put on a shirt and still look like I wasn't an adolescent boy! I will drop the money to not only look good, but feel good! The internal structures you can feel supporting uniquely and effectively. Buy this bra, you won't regret it!!!

I'm a 36 B and a medium seems a little too tight around the rib cage.

It's certainly better than cotton, but it's not the best I've used. I wear 36B and ordered a M A/B. I really liked the band width, but it would be much better if it had a hook enclosure. However, there was better than mediocre support, but there was still some bouncing. Lately the best product I have found is an UnderArmour's Strength 1 bra (although doesn't have hook enclosure either) has given me the best support for high impact exercise.

definitely great support.. Don't need 2 bras anymore, this is great. however, it was hard to get into and a beeyotch to get out of - but once on, fit great. it's still sorta uniboob but not horrible.. but then again, i'm a D cup so what can I expect? At least it works very well and i'm happy to run with it. might consider one that zips in the front to better get in/out of!

I had to send this back. I would suggest that if you are a 34 B that you try a size small rather than a medium. This medium felt loose in the cup and not very supportive, hence defeating the purpose of an expensive bra. However, I got the firm support in a 34B and kept it. The elastic is not super comfy either, kind of chafing. I'd like to see a company come out with some good support for smaller sizes. I'm disappointed in CWX bras--love the tights.

Love everything about this bra: the material, the fit, the support, the color (I have the rose pink). I have worn this bra in the gym, on the trail, and while biking. It doesn't chafe at all, even during extended work outs. I'm a 34B and the medium fits great.

I kind of questioned this sports bra when I first got it; it wasn't like what I was used to. Since that day, I realized I shouldn't question perfection. It is supportive and comfortable. I haven't had any issues with chafing or anything.
