The ALS Liner enhances the warmth of the M-65 Field Coat. Unlike other liners, the ALS was designed with a double function allowing it to be worn both as a liner and separately as a light-weight jacket. Made from ripstop nylon outer fabric with polyester interlining. Features fabric binding around two front pockets, bottom hem and knit cuffs. Designed to attach to the M-65 Field Coat by button-hole tabs, however it can be worn under any coat type jacket.
