The USGI M-65 Cold-Weather Quilted Pant Liner is a genuine U.S. military issue item designed for use with M-65 field trousers. Made from durable rip-stop nylon with polyester batting insulation, it provides critical warmth in cold environments while remaining lightweight. Quilted construction evenly distributes insulation, and button-hole tabs allow secure attachment to M-65 field pants. Side openings with button closures allow easy access and removal without taking off the outer garment. Built for soldiers in the field, these liners are tough, functional, and ideal for surplus collectors, outdoorsmen, or anyone needing dependable cold-weather layering.
