Slather up with mineral sunscreens, sure—but also consider adding a layer to your adventure wardrobe: a sun shirt. But then I learned that sun-protective clothing isn’t just a marketing ploy; it’s manufactured to actually prevent (most of) the sun’s UV rays from hitting your skin. The higher the UPF rating, the better the protection—50 UPF will block 98 percent of the UV rays (and that’s both the UVA and UVB types) from passing through the material. ), and color itself lends a hand to the defense—contrary to the popular notion that light colors are best in the sun, darker (and brighter) ones will better absorb UV rays. The Mountain Hardwear Crater Lake Hoodie is light, soft, and boasts a 50+ UPF rating.
