The new Stalker ATP (All-Terrain Pant) is a lighter, more packable version of our highly acclaimed ranger ATP. What really sets this pant apart from most is the weatherproof ventilation zippers located at the outside thigh. Simply unzip during periods of high activity to vent excess body heat. With our Diamond-Flex Crotch providing more stretch and comfort where needed, the Stalker ATP won't just be the best all-around pant you own but also the most comfortable. Made from the new H2P L.A.W. System, it offers full protection spring through fall.
