19 Pairs Of Workout Underwear For Your Sweatiest Gym Days

For most of us, "workout underwear" is whatever we grab while packing a gym bag or what we are already wearing during the day. There's already so much other gear that underwear isn’t usually top of mind.

But hear me out: Have you ever done Pilates wearing lace underwear and ended up with an imprint of the design on your butt? Or gone on a run and chafed so much it turned into a walk? Or taken an indoor cycling class and left with a sweat-soaked crotch? If the answer is yes to any of those, you may want to consider getting workout-specific underwear.

Workout underwear can make exercising more comfortable because it's often made from smooth, stretchy fabric like nylon that wicks away sweat and moisture — and that's important from a health standpoint. Bacteria and yeast that cause vaginal infections love hanging around warm, wet environments, so wearing underwear that manages moisture (and also taking off your sweaty leggings and underwear once you're finished exercising) can help prevent vaginal infections, according to experts.

Convinced you need some new underwear? Ahead, we found the best styles to wear while working out or any other sweat-inducing activity.
