We took the best qualities of boardshorts and wetsuits to build these versatile insulated pants. Built from 100% recycled polyester stretch boardshorts fabric with a warm and fast-drying thermal wetsuit lining, they’re an innovative solution for pre- and post-surf warmth. Made in a Fair Trade Certified™ factory.
