To use this rash vest, simply put it on like a regular shirt before hitting the waves. It's designed to fit snugly, so pull it down until it sits comfortably on your torso. For a better fit, adjust the elastic boardshort loop around your waist. When it comes to care, rinse the vest with fresh water after each use to remove salt, sand, and chlorine. Hang it to dry in a shaded area, away from direct sunlight as it may fade the prints. Avoid using harsh detergents or fabric softeners, as they can damage the fabric and reduce the UV protection. With proper care, your rash vest will last for many beach adventures.
