Big support for big cup sizes.

The CW-X Women's Xtra Support III Sports Bra pulls out all the stops to provide maximum comfort, support, and moisture management on your next run. Designed for high-impact activities, the Xtra works best for B, C, and D cups. Made with a CoolMax and Lycra fabric blend and a LiteStretch mesh back, the Xtra wicks moisture away from your skin, dries quickly, and supplies exceptional breathability. A stretch mesh internal venting channel under the bust line helps with breathability and evaporation. 

Its patented five-point CW-X Targeted Support Web comfortably supports each cup with an extra layer of mesh web material reinforcing the front cup panel of the bra. In addition, the Xtra's crossover racerback design reinforced with support webbing provides stellar back support during long runs or intense training. A wide stretch back ensures extra support, while a back hook-and-clasp closure supplies added convenience and helps prevent over-the-head stretch-out over time.

Very supportive, and a great price! I’ve worn this bra on long runs and there is barely any bounce. Definitely one of my favorite bras now.

Very fitted and supportive. Good for running and other high impact sports

SUPER supportive

This is the old ironsides of sports bras. Fantastic soft-structured support, really high-quality materials and construction that locks you in tight for zero bounce, zero sag. I bought one size too small, and found it too restrictive, but am positive the larger size would have worked perfectly for comfortable support during even the highest-impact activities.

Like the bra -- fit is wrong

I normally wear a 36C. This bra definitely fits more towards the B cup. fortunately I was able to give it to my daughter and she likes it. Good fit for her.

New favorite

UPDATE: Bought another one of these bras and am still in love. The first one I bought is still good as new, despite frequent use and washing.


I've been using Calvin Klein sports bras for years and finally decided to try something new. Long story short, I haven't worn my old bras since purchasing this one!

Is it a miracle and magically holds my breasts in place with zero movement? No, and I'm not sure such a bra is possible. Am I comfortable on my runs? Yes, absolutely, and that's all I want.

I'm petite but fairly well endowed (usually a 34B or 34C). I used to wear regular bras underneath my sports bras because I couldn't find anything supportive enough. I'm so happy to have found this bra; I feel very confident, yet still unrestricted.

The colors are very pretty, too. :)

After years of prodding my wife to buy this bra in place of doubling or tripling up on sports bras I finally got her to give it a try, and she couldn't be happier. The wife has always struggled with compression style sports bras, but this bra provides maximum comfort and support. Here are her thoughts:

As soon as I wore this for the first time, I placed an order for a second and started telling all my friends about it. Best sports bra I'€™ve ever owned.
Incredibly well constructed. I machine wash them and air dry them and they look like new every time
I can wear this bra all day and my shoulders and neck aren'€™t strained. They didn't quite come in my size so I went down and cup size and there'€™s enough of a give to where the bra feels a little tight but not too bad
This sports bra is awesome. No jiggle, no neck strain, just allows me to be active while holding everything in
These are definitely pricey but worth it. I've had to double up on sports bras before I bought this one.

Finally convinced her and she's in love

My wife loves this bra for running and other high impact sports. It wicks well and doesn't chafe.

This has been my go-to bra for running for years. I run longer distances and have had great success with this bra. The fit this comfortable, it seems to last a long time. I have used the CW-X bra for several years and do not plan to change.
