To use this wetsuit, simply put it on like you would any other wetsuit. Make sure it fits snugly but not too tight. When you're swimming, the wetsuit's buoyancy will help you stay afloat better, so focus on using your arms and legs to move forward. As for maintenance, rinse the wetsuit with fresh water after each use to remove salt, sand, and chlorine. Hang it in a cool, dry place away from direct sunlight. Avoid sharp objects that could tear the wetsuit. If there are any small holes, you can use a wetsuit repair kit to fix them.
