The Men's Wavefarer Boardshorts 19" by Patagonia are casual swim shorts for surfing or lounging on the beach. The boardshorts are made from a recycled polyamide fabric that is impregnated and therefore resistant to moisture and dirt. The polyamide is obtained from old fishing nets. The shorts have a lined waistband with a drawstring, protect you from the sun's rays and can be packed away in the zip pocket on the leg when you've had enough of the water and beach.
