The 5 Best Sports Bras for Size D/DD

Great sports bras are more than mere garments. They're engineering marvels that can help runners extend their workouts, improve running form, and even avoid injury. Researchers at the University of Portsmouth in England found that excessive breast movement can result in heavier, injury-promoting landings. But a properly fitted bra can reduce breast bounce by half, making it one of the best investments a runner can make. Happily, our team of a dozen sports-bra testers—who ranged in size from 34A to 36DD—analyzed 49 different bra models and discovered that the top performers don't always command top dollar.

In addition to D/DD shown here, we also reviewed A/B and C/D.

TESTERS' FAVORITE

This tank-style bra is comfy and supportive—and doesn't employ the orthopedic styling so typical of bras for larger cup sizes. "The first bra I've found that I'd wear without a shirt," said one DD tester, who found the compression and encapsulation "flattering." $79; 32C-38DD

EASY ON/OFF

The front zip looks sassy and makes for no-hassle removal—even after sweat-soaked workouts. Adjustable racerback straps stay firmly in place, and their meshy fabric kept testers cool throughout hot midday "No bounce, no chafing," reported one tester. $42: S-XL

BOUNCE ELIMINATOR

If zero bounce is your priority, this bra delivers. "Fit is very snug and rigid, with very little give in the bottom band," reported one D-cup marathoner. Vertical shoulder straps convert to a crossback, and the combo of side compression and molded cups is figure-flattering. "I look like a Cosmo cover girl," said one tester. $58; 32-36C to DD, 38C-D

DAYLONG COMFORT

Often, the most supportive bras aren't the most comfortable—but the innovative Ladder Back is so wearable, testers kept it on for hours after their run. "It feels breathable and stretchy," said one, who liked the freedom of movement provided by rows of elastic in the back. The quick-dry, sweat-wicking fabric minimizes clamminess. Bounce is negligible. $60; 28C-44F

SIMPLE STABILITY

Most pullover, tank-style bras don't deliver enough support for large-breasted runners, but this one, while it didn't eliminate bounce, "really minimized it," said a DD tester. some testers reported that it created little separation (yep, uniboob), but others gave it props for the simplicity of its design. $60; 34B/C-38DD
