Using this wetsuit is easy. First, zip it up through the chest zipper. Make sure the sleeves fit well on your arms. When you're in the water, the watertight seams will keep you dry and warm. As for maintenance, rinse the wetsuit with fresh water after each use to remove salt and sand. Hang it to dry in a cool, shaded place, away from direct sunlight as it can damage the neoprene. Avoid sharp objects that might tear the wetsuit. And store it flat or hanging when not in use to maintain its shape.
