Find peace in the Akamai Pant, featuring Insect Shield® technology. 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). Whether you're trekking through ruins or lounging in camp, these cotton blend pants will keep you comfortable and looking good. Insect Shield repellent lasts through 70 washings. Do not dry clean.
