To use this wetsuit, first make sure you're dry and wear a thin layer of clothing if you like. Step into the wetsuit from the bottom and pull it up carefully over your legs, torso, and arms. When you're in the water, the wetsuit will keep you warm and buoyant, helping you swim better. As for maintenance, rinse the wetsuit with fresh water after each use to get rid of salt, sand, and chlorine. Hang it to dry in a cool, shaded place. Don't leave it in direct sunlight or a hot car. Also, avoid sharp objects that could tear the wetsuit. When storing it, fold it gently and keep it in a dry spot.
