Honestly? No one wants to feel their underwear creeping up their butt or feel sweat dripping in uncomfortable places while they’re exercising. If either of those situations has happened to you recently, a new pair of the best workout underwear for women can help. Now, we know that may be easier said than done; the undies that claim to be sporty and sweat-wicking don’t always live up to their claim.

It all comes down to finding undies that will keep you cool, dry, and comfortable while you’re in the midst of an intense sweat sesh.“Since moisture is at the root of the issue, we want a fabric that will wick it away,” says Kristen Hislop, the owner of Hislop Coaching.
Easy as that, right? Right. To help you narrow down your choices, we got the insights of fitness enthusiasts and trainers like Hislop to share advice on the best underwear to wear while working out.

What to look for in workout underwear
In addition to choosing the right fabric, the best workout underwear comes down to a few specific design features.
- Cut: The undie cut you choose can be as much of a personal preference as the choice to wear them at all. Maybe you like thongs, maybe you like briefs, and either way, that’s okay. Hislop notes that briefs have more tummy coverage, and hipsters are great under leggings if you’re not a thong fan. “If you tend to have thigh chafing, then you might like a boyshort with a bit of length in the leg,” she says.
- Size: Be sure your workout underwear fits well. “For comfort and performance, workout underwear should fit snug, but not so tight they constrict movement or create visible lines on the skin,” Booth advises. She also recommends avoiding underwear that’s too big, since that can create bunching and chafing.
- Climate: Both Hislop and Booth point to this as a consideration when choosing workout underwear. “Ask any runner who’s been out for a cold run and has a frozen butt when they return,” Hislop says. “Merino wool and bamboo underwear can be great for cold climates—they have fantastic wicking properties, but will also keep you warm.”
Conversely, the type of workout underwear you choose is important for warmer weather, too. “If the weather is hot and humid, less fabric like a thong may be preferable,” Booth says.

“Lululemon is a personal favorite for all things workout wear,” Booth says. “Its quality, durability, and style are hard to beat.” Such is the case with these thongs, which are designed in a silky soft, stretchy modal that’s both quick-drying and sweat-wicking. They’re great for a variety of activities, from yoga and pilates to weightlifting and running. Each three-pack comes with a variety of fun colors, and the mid-rise waist won’t dig in while you bend and squat.
Hislop is a fan of multiple Lululemon underwear styles, too, including the high-rise bikini, mid-rise bikini, and high-rise shorties. “They have seams but are stitched so you can’t feel them,” she says of the high-rise bikini specifically.
