A nursing sports bra that’s actually good for running

I was a 34A before I got pregnant and have been dreading looking for a postpartum running bra because the feedback I have gotten is that a good one doesn’t exist. I found the Chloe after doing a lot of research online and bought the recommended size based on the guide (M). The bra is very comfortable and the straps are attractive, but would be more functional if they were adjustable. After a few runs in them I became curious if a smaller size would help with some unwanted bouncing while running at quicker speeds. I purchased the small, and am much happier with the fit! I’ve got much less movement during activity and can still fit my Elvie in there to pump before running.

If you are a runner looking for a good bra for return to sport postpartum, I would recommend this one. HOWEVER, wait to buy it until you are able to thoroughly test it - I purchased mine during my second week postpartum and couldn’t fully test it until a few weeks later. As a result, I am now outside the window to exchange the two medium bras I bought for size smalls. The return/exchange policy only covers the first 30 days! An expensive mistake if you miss it :(

Great bra

These are the best nursing sports bras by far! Have yet to try the pumping version but I have been wearing this one nonstop, working out or not. I would love one with even more support or adjustable bands for big chests.

Hi there,

We appreciate your feedback about support and adjustable bands for larger chests, and we’ll be sure to share this with our design team. We’re also excited for you to try the pumping version—let us know what you think when you do!

Best,

Great nursing bra to exercise in

Material seems high quality and love that the pads stay in place well. Gives great support, way better than my other nursing bras. My only complaint is that it can be difficult to put on. You have to pull in on like a shirt and it’s tight. The clasp back doesn’t really help that much because it still crosses in the back. But overall I love how much support this bra provides and the look of it.

Hi there,

Thank you for your feedback! We're so glad you love the quality, support, and look of the bra—it means a lot to us. We appreciate your input about its fit and clasp design and will share it with our team for future improvements. Your trust in our brand is greatly valued!

Best,

I stocked up!

After trying several nursing and pumping bras I’ve finally found the brand for me. I bought my first bra because I was ready to workout again but wanted to be able to nurse and pump before or after my workout without changing. These bras have now become my daily bra. They are so comfortable, cute, and functional. With a larger chest, the normal pumping bras did not work for me comfort and fit wise. It feels like these bras were made for me!

Hi there,

Thank you so much for sharing this—we’re absolutely thrilled to hear you’ve found the bra that works for you! It means the world to us to know our design has made a difference, especially for moms with a larger chest who need both support and functionality. Your kind words truly motivate us to keep creating products that support amazing moms like you!

Best,
