Veteran backpackers along sections of the John Muir Trail north of Yosemite have been known to weep in frustration as thick clouds of mosquitoes descend on them from heaven’s know where. Now, hikers everywhere can rejoice and keep their heads held up high with the Outdoor Research Bug Net Cap. Made with Supplex nylon fabric UPF 30, the versatile cap features a no-see-um 100% polyester netting that keeps bugs and no-see-ums off the face and neck. A drawcord closure seals the netting fabric. And when the bugs are gone, the netting can be tucked into a pocket at the back of the cap. A wicking headband manages your sweat. $35. Outdoor Research.
