Whether it is paired with another BugsAway style or a regular piece, the Kokua Legging, which features Insect Shield® technology, will help keep pesky bugs at bay. 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). Perfect for layering under a dress or tunic, the Kokua is a great basic that will always find it's way into your bag. Insect Shield repellent lasts through 70 washings. Do not dry clean.
