Keep The Girls Happy: Running Sports Bras

Tough Decision? We're Here to Help

Your sports bra is pretty much your most important piece of run gear. And like Joanna at right here, you may be overwhelmed by your options. But don’t fear – we’re here to, er, ‘support’ your effort to find the perfect run bra.

We recently tested seven different models to figure out which bras work best for women of different cup sizes. Choose the size that’s right for you and read on!

If you need help figuring out what size bra will fit you best, check out our Sports Bra Fit video on the Learning Center.

A or B Cup Bras

Women who are smaller up top can get away with a ‘less is more’ philosophy when it comes to sports bras. A classic compression sports bra often provides enough support, and can be a super comfy option, as many classic compression bras are seamless or nearly seamless. If you’re a smaller busted woman looking for more support, then try a bra with encapsulation and compression.

Bras Tested:

Best Support Overall: Moving Comfort Vixen

Alice says: “This bra offered superior support, with a great feminine silhouette. The back mesh is very breathable and stood up to hotter temps.”

Best for Longer Runs: Moving Comfort Phoebe

Alice says: “The snug compression of this bra gave me plenty of support for high impact activities, and was comfortable enough to wear for a long day on the trail.”

Stand-Out Feature: The North Face Stow-N-Go

Alice says: “The pockets on this bra are awesome! Because of the padding, even and iPhone fits comfortably in the large one. This was the least supportive of the bras I tested, but it still offered adequate support for running.”

B or C Cup Bras

For women who wear a B or C cup, encapsulation helps to provide enough support to keep the girls happy as you head out to hit the roads or trails. For even more support, try a bra that also has adjustability. If you can adjust the straps or the back closure of a bra, it will let you create a more custom fit for your body and your needs.

Bras Tested:

Best Support Overall: Moving Comfort Juno Bra

Joanna says: “The complete, high coverage really kept movement to a minimum. I didn’t even have the have the straps tightened much just because the bra supported me almost without them.”

Best for Longer Runs: Asics Adjust Bra

Joanna says: “This bra is very supportive because of the adjustable straps, yet it lets you keep your feminine shape. It has very soft seams and fabric that keep chaffing down to a minimum.”

Stand-Out Feature: Moving Comfort Phoebe Bra

Joanna says: “This bra is very supportive for a classic compression bra. It’s nice to have back adjustability in a classic compression bra.”

C to DD Cup Bras

To help eliminate the bounce, reach for an adjustable encapsulation bra. When you have a larger bust, it’s very important to make sure that the majority of the support in your bra is coming from the band (and not the straps) to alleviate back pain caused by too much pressure from straps. For an even snugger fit, reach for a bra that has compression as well as adjustable encapsulation.

Bras Tested:

Best Support Overall: Moving Comfort Juno Bra

Mariko says: “This bra is very supportive, has great coverage and is good for modesty. I went up a cup size and loosened straps to help keep the straps from cutting into front underarms, but it could become an issue for long runs.”

Best for Longer Runs: Moving Comfort Grace Bra

Mariko says: “This bra is comfortable, soft and breathable. I wore this in hot (90-100 degree) weather and it stayed quite dry. Zipper closure is easy to use – no issues there.”

Stand-Out Feature: CW-X XTempo Support Bra

Mariko says: “This bra is my favorite of the three for comfort and appearance. Fabric is very breathable and stayed quite dry. Hook-and-eye closures are easy to use and make the front flexible to curves.”

    I’m a D cup and trying to find one that doesn’t result in a uniboob!! unfortunately the moving comfort ones do just that. if you’re not a fan of the uniboob look, avoid those!

  • Elizabeth

    The problem with the bras for the D and DD cups is that there is so much material. It’s not comfortable or flattering if you want to run in just your sports bra. I haven’t seen any American company do as well as European ones in the sports bra department. Bras such as the Shock Absorber and the Z Sport line have paid much more attention to breast anatomy and how to protect tissue from getting too compressed. Once I tried these brands I never went back to Moving Comfort. It would be great to see RunningWarehouse carry Shock Absorber, ZSport and Thuasne– all from Europe.

  • Alice

    You might try the CW-X Ultra Support Bra or the CW-X XTempo Support Bra for great support and a feminine silhouette.

  • Alice

    Thank you for your feedback, Elizabeth. We are always looking into carrying products that meet the needs of our customers, and will look into your suggestions. In the meantime, you might check out the CW-X XTempo Support Bra for great support with less fabric.

    I’d love it if your product descriptions would include whether the bra has shaped cups or a thicker lining to take care of the headlights. I don’t care when I’m running, but I need a few for those days when I expect to be seen in public afterwards. Any suggestions for an A/B cup?

  • Alice

    Thanks for your question, Elodie. When a bra description mentions ‘modesty’, it’s referring to a thicker liner or molded cups that will, um, ‘cut the lights’, if you will. The Moving Comfort Juno might be a good option for you.

    Moving Comfort uses heavy fabric which gets soaked and then chafes badly. Another vote for carrying more D-DD sports bras. +1 to Shock Absorber (B4490) and Under Armour Endure and Champion Double Dry.

  • Steph

    I think you are one of the best providers of running sports bras for the girls. All the seven different models of the bras that you have tested provide the more options for the women of different cup sizes.

  • sid

    I tried the Bra-llelujah and did not have much success. I really needed adjustable straps to provide better support for my girls.

  • Cathy

    The bra fit perfect and provided excellent coverage. The bra holds the moisture in, which is great. I love this bra!
