The Youth Solar Long Sleeve is for adventure or daily wear. Offers UPF 50+ sun protection and cooling performance qualities while kids are swimming at the pool or the beach, playing sports, riding bikes, and more. In colder weather, it's an excellent base layer for wicking and warmth without adding bulk. Countless hours of outdoor activities have been logged in our shirts. Plus, wearing a UPF 50+ shirt means less chemical sunscreen on children's skin and in the pool.
