The Best New Sports Bras For A-Cups

The wrong bra can completely sideline a workout. Fabric friction and breasts moving in different directions is the last thing you want to think about when running 400-meter repeats. Plus, ouch! One in three women says her girls hurt during exercise, and the number goes up with bra size. Luckily we found the right sports bras—lots of them! We had dozens of testers run in dozens of designs to find the best, high-impact fit for every shape and size.

First up, we share the best sports bras for A-Cup runners. Don’t worry ladies—sizes B through F are coming soon!

Focus on finding a smooth, snug fit—extra fabric leads to painful nipple chafing—and a style that doesn’t ride up when you push the pace.

C9 by Champion Enthusiast Seamless Cami Sports

Wicking fabric helps you keep your cool in this sporty cami-style bra top. The easy-on-your-wallet price point means you can get one in every fun color! “I’m a big fan of the thin straps. They do the job without going overboard,” explained one tester.

Oiselle Moto Tracktion

As one A-cup put it: “It gave me subtle shape without being like, “Hello, here are my boobs!” Really, what more could you want in a bra? Coverage and gentle shaping, with a breathable mesh racerback, do the trick beautifully.
