To use this rash vest, simply put it on like a regular shirt before you head out for a surf. It's designed to fit snugly but still allow for easy movement. When it comes to care, after each use, rinse it with fresh water to remove salt and sand. You can machine - wash it on a gentle cycle with mild detergent. Avoid using bleach or fabric softeners as they can damage the material. Hang it to dry in the shade to prevent fading. Also, make sure to check the vest regularly for any signs of wear and tear, and replace it if needed.
