Rashguard suits are no-brainers for children and surfers, and now they've hit the mainstream, with more fashionable options than ever. Offering extra coverage and sun protection (all of these pieces have UPF—ultraviolet protection factor), they're also perfect for swimming, lounging, and poolside cocktailing. Just don't forget to put sunscreen on exposed areas so you can soak up the sun guilt-free.
