These expert-approved picks will keep you cool, dry, and comfortable–even while you sweat.

Sweating down there is inevitable—whether you’re working out in the gym or running errands outside all day in hot weather. Thankfully, though, the best moisture-wicking underwear can help keep you dry and comfortable—even while you’re sweating up a storm.

"Moisture-wicking underwear is designed to absorb sweat and moisture, rather than letting it remain on your skin," says Lauren Penzi, M.D., F.A.A.D., a board-certified dermatologist in New York. According to Dr. Penzi, sweat and moisture build-up in your groin region can not only irritate your skin, causing symptoms like vaginal itching, burning, or redness, it can also promote the growth of bacteria, yeast, and fungi. "By mitigating stagnant sweat on the skin, moisture-wicking underwear helps prevent irritation and potential bacterial or fungal infection," she explains.

When it comes to shopping for moisture-wicking panties, you’ll want to seek out fabrics like polyester, nylon, spandex, wool, and mesh, says Sherry Ross, M.D., OB/GYN, women's sexual health expert and author of She-ology and The She-quel. But with so many options for underwear out there—including countless fabrics, styles, and fits—it can be hard to find the best pair for your needs. That's why we’ve rounded up some of the best, most top-rated moisture-wicking underwear picks right here (including the best seamless underwear options) — all approved by experts to help keep you dry and comfortable.

Meet the Experts: Lauren Penzi, M.D., F.A.A.D., a board-certified dermatologist in New York; Sherry Ross, M.D., OB/GYN, women's sexual health expert; Marisa Garshick, M.D., a board-certified dermatologist at Manhattan Dermatology and Cosmetic Surgery in New York.
