Chloé 4 Running Nursing & Pumping Sports Bra (Houndstooth)





Good Housekeeping 2021 Parenting Awards winner.

Runs one size bigger compared to regular sports bra brands. E.g, for 34DD/DDD, it's typically a size S buckling up on the middle hook. Please measure yourself and choose the size you prefer. A larger size will provide a slightly looser band fit. A smaller size will be slightly tighter. You decide what feels best.

    Great bra

    I wear this bra almost everyday. I ride horses so I was looking for something supportive yet easy to nurse and it’s just that. Normally wear a 34C pregnant and nursing went to a 36d I bought a M. And it fit with a little room to breathe. Probably could fit a small but I didn’t want something super tight.

    Love it!

    Very supportive and comfortable, and looks good as well. I’ve used in running and strength training. Easy to breastfeed. I am petite and debated between xs and s and glad I got the xs.

    Not very supportive

    I do like this bra for everyday wear and low impact workouts, but i wish it was more supportive. I also wish this style had adjustable straps like some of the other bras do.

    Good support

    One of the most supportive nursing bras I’ve found for larger breasts. Unfortunately was charged enough duties to have bought a whole other bra. Wish there was a way to put it on without slipping it on overhead.
