Forget diamonds–a first-rate sports bra is a hiking girl's best friend. The Handful supports without squishing, so it stayed comfy after 12 hours of wear. The straps never chafed during trail runs or when worn beneath a backpack (the bra's cross-back design reduces competition with pack straps). And it wicked moisture better and dried faster than any other bra I've worn: The honeycombed polyester liner fabric kept the Handful from ever feeling clammy, while the outer "shell" fabric (made of 82 percent nylon and 18 percent Spandex) provided support.
Positioned between those layers, removable cups provide extra padding, so even when worn beneath an ultralight shirt or even out to dinner, the Handful smoothed contours rather than indecently revealing them and the center seam eliminates the monoboob effect and creates a flattering profile. Plus, it has a nice, finished look that doesn’t scream ‘underwear!’ so I could wear it swimming in mountain lakes. Best for hiking, biking, climbing, and running for A to C cups. (D cups will want more support for all but low-impact activities.)
