Everyone should own a rashguard for ultra sun protection of 50 UPF which is equivalent to 150 SPF. Wear rashguard surfing and boogie boarding to prevent rashes on chest and arms. Great to wear while swimming and snorkeling to protect from sun. Fits small, so order one size up from your men's t-shirt size.
