The US Army M65 Combat Pants Liner, Size Medium, is a genuine component of the M65 field uniform system used by the United States military. Designed to provide additional insulation, the liner is intended for insertion into the M65 combat trousers, offering enhanced warmth and comfort in cold weather conditions. Constructed from quilted polyester batting with a smooth nylon outer shell, the liner is lightweight, compressible, and features buttonholes along the waistband and legs, allowing for secure attachment inside compatible M65 pants. This particular liner is marked as size Medium, typically fitting corresponding standard-issue M65 trousers. The M65 uniform series was introduced in the 1960s and remained in widespread use for decades, valued for its durability and adaptability in a range of field environments. Liners such as this one have also been adopted for non-military use due to their practical insulating properties. This item represents an original example of US military cold weather gear.
