The men's Atom LT pant can be worn as a warm outer on cool, crisp day hikes, or an extra insulating mid layer during frigid mountain activities. It's padded with 60g of synthetic Coreloft insulation for warmth, and furnished with a light, durable, abrasion-resistant Tinthan nylon ripstop face fabric. This blend of lightweight and stretchy materials is complemented by articulated patterning on the knees and seat for even more active and natural-feeling flexibility. The pant comes with full length separating side zippers, allowing quick changes when wearing hiking boots and crampons. The zippers are backed by a laminated wind flap, and bottom snap closures secure the lower hem. The waist is elasticized for a more precise and comfortable fit, while the lower leg cuffs have drawcords that can be tightened around boot tops.
