Olive green waxed cotton outside, cotton lining. Two rows of buttons/snaps. Some discoloration on snaps (oxidized) gentle wear and tear but adds to the vintage look and feel of the coat. Men’s XL measurements are approximate: 27” armpit to armpit and about 51” long. Lightweight for travel. This is a rarity! Wax can be purchased online to further waterproof the coat. Has 2 pockets in the front also. Make me an offer on this gem! Comes w/canister of wax.
