Head from the trail and back into town for dinner without missing a moment in the ExOfficio Men's BugsAway Sandfly Lightweight Pants. Keep your passport secure and accessible in the drop-in leg and hook-and-loop back pockets. When the weather heats up, roll up the snap tabs at the legs and convert the pants into shorts for comfort. Whether in the backwoods or the backyard, Insect Shield technology helps keep you protected with built-in invisible, odorless insect protection that repels mosquitoes, ticks, ants, flies, chiggers and midges (no-see-ums). The active ingredient in Insect Shield products is so tightly bonded to the fabric fibers that it retains effective repellency through 70 washes.
