To use these boardshorts, simply put them on like regular shorts before you head out for a surf. The hidden zip pocket is great for storing small items like keys or a credit card, so keep that in mind when packing. When it comes to care, rinse them with fresh water after each use to remove salt and sand. You can machine - wash them on a gentle cycle with mild detergent. Avoid using bleach or fabric softeners as they can damage the fabric and the sublimation print. Hang them to dry in a shaded area to prevent fading. With proper care, these boardshorts will serve you well for many surfing adventures.
