To use this wetsuit, start by unzipping the chest zipper. Put your legs in first and then gently pull it up over your torso. Zip it up all the way to the top. When you're done using it, rinse the wetsuit with fresh water to remove salt, sand, and other debris. Hang it to dry in a cool, shaded area. Avoid direct sunlight as it can damage the neoprene. For storage, keep it flat or hang it on a wide - hanger to prevent creasing. Also, don't leave it in a damp place to avoid mold growth. This wetsuit is designed for boys aged 8 - 16, so make sure it fits well before wearing it in the water.
