Whether you're crushing laps at the pool or catching waves at the beach, the Saxx Droptemp Cooling Hydro Liner transforms your swim experience from the inside out. Designed specifically to wear under unlined swim shorts, this innovative men's underwear features DropTemp cooling technology that actively regulates your body temperature while the signature BallPark Pouch provides anatomical support that prevents chafing during every stroke, dive, and beach volleyball spike. The quick-dry, quick-drain construction means you'll transition seamlessly from water to land without that clingy, uncomfortable feeling, while the chlorine and saltwater resistance ensures this hydro liner maintains its performance and color season after season. It's the game-changing foundation that lets you focus on perfecting your backstroke instead of adjusting your gear.
