Made of insect repelling fabric, the Sentinel was designed to keep swarming no-see-ums and mosquitoes from snacking on you, so you can relax at camp and enjoy the quiet of the wilderness. Full coverage arms and a collar that can be rolled up above the ears provide protection from your wrists to your head. Lightweight, breathable fabric allows body heat and moisture to quickly escape if you need protection from the pests on your way down a sun-baked trail.
