For the most dynamic movement, our simplest and most minimal surf trunks are now made from superlight, fast-drying 87% recycled polyester/13% spandex blend with a DWR (durable water repellent) finish and 50+ UPF sun protection. The streamlined performance fit is optimized to reduce binding and chafing, and we've replaced a traditional, multipiece waistband and fly with a fused waistband that eliminates a fabric layer and conforms to the shape of the hips, staying snug to the body through a full range of motion. For travel ease, the shorts can also pack snugly into the small pocket on the seat, which has an internal key loop and a non-corroding, recyclable plastic zipper with pull cord for ease of use. A notched hem provides additional mobility through the leg. Outseam is 18". Fair Trade Certified‚Ñ¢ sewn.
