Using these boardshorts is easy. Just put them on like regular shorts. The drawcord closure allows you to adjust the waist for a perfect fit. When you're out surfing, the 4 - way stretch fabric will move with you, giving you maximum flexibility. After use, rinse them in fresh water to remove salt and sand. Hang them to dry in a shaded area to avoid damage from direct sunlight. Don't use harsh detergents when washing them, as this could damage the fabric. Instead, use a mild detergent and wash them on a gentle cycle. This will help keep your boardshorts in good condition for a long time.
