Using these boardshorts is a breeze. Just put them on like any other pair of shorts before you head to the beach or engage in water sports. When you're in the water, the DWR treatment will keep you dry and comfortable. As for maintenance, after each use, rinse them with fresh water to remove salt and sand. You can machine - wash them on a gentle cycle with mild detergent. Avoid using bleach or harsh chemicals as they can damage the fabric and the water - repellent treatment. Hang them to dry in a shaded area to prevent color fading. Also, be careful not to snag them on sharp objects to keep the woven construction in good shape.
