Whether you're in a buggy town or hanging out in camp, the BugsAway Kutula Tunic, featuring Insect Shield® technology, is the perfect shirt to keep you looking good and protected at the same time. 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). The comfortable cotton blend breathes and dries quickly for easy care, and side ties let you customize the length. Insect Shield repellent lasts through 70 washings. Do not dry clean.
