Get insect protection with a classic baseball style hat. The BugsAway Classic Cap, which features Insect ShieldŽ technology, saves your face from bites and burns whether you're on a trail or out fishing. Permethrin, the active ingredient in Insect Shield, is invisible, odorless, and so tightly bonded to the fabric fibers that it retains effective repellency through the life of the garment. It repels mosquitoes (including those carrying West Nile virus and malaria), ticks, ants, flies, chiggers and midges (no-see-ums). Insect Shield repellent apparel lasts through 70 washings.
