The BlackStrap Daily Tube sun mask is my can't-leave-home-without-it fly fishing (if not all outdoor) essential. It's a multi-functional tool, lightweight, super breathable, and quick-drying, that will protect you against the elements. The face mask keeps you cool and protected in the blistering sun, dries quickly when damp and adds thermal warmth for cutting cold winds. UPF 50+ UV Protection. When the wind comes up, I just pull it over the crown of my cap and my hat's secure and I'm warm. Select more that one - you know you want to!
