Reebok Workout Ready

$35; Fits cups A–B (sized 2XS–XL)

This multi-purpose sports bra does a good job minimizing bounce for runners needing light support. The Speedwick tech is adequately breathable, even for longer, sweatier runs. Nice touches such as the keyhole back design and a slightly more modest neckline cut so you can feel confident running without a shirt on a hot day. Our testers reported that the embedded straps are quite comfortable.
