The outer shell is made of custom, quick-dry SEAWASH™ fabric, with interior briefs made of EVAP poplin nylon that dries fast and stays comfortable wet or dry. You'll never have a pocket full of water or inflated swim trunks with our special grommeted design. Velcro back pockets ensure nothing important falls out, while angle-cut front pockets allow for easy access. The super-soft interior waistband is comfortable enough to wear all day, even with a belt.
