Using this surf cap is easy. Just slip it on your head before you hit the water. Make sure it fits snugly but not too tight. When you're done with your surfing session, rinse the cap with fresh water to remove any salt or sand. Hang it in a cool, dry place to dry. Avoid direct sunlight as it can damage the neoprene. Also, don't machine wash or dry the cap, as this can affect its quality and stitching. With proper care, this cap will serve you well for many surfing adventures.
