These are genuine US military surplus M-65 Field Jackets, available in Olive Drab green and Black. The jackets have four front pockets, a hood that stores inside the collar, and a metal zipper closure with additional button snaps.
There is an optional liner (not included) that can be added to this jacket to add even more cold weather capability. The liner securely attaches with buttons on the inside of the jacket.
These jackets appear to be unused to us, however we cannot tell for sure whether they are brand new or not. They may have a small amount of dirt or other minor imperfection from storage.
