M-65 Field Jacket Liner
The field jacket liner is one of the greatest pieces of cold weather gear the military ever produced. Same material as a "woobie" (Poncho Liner) just in jacket form. Can be buttoned into the M-65 field jacket or worn separately under a shirt or jacket. Polyester filled so it will keep its warming qualities even when wet. Can be modified with a zipper for use as its own outer garment.
