I had to do a fair amount of research to identify the brand of this coat as well as it's size. It has no tags at all. But with the help of the "world wide web", lol—I have done my best to nail down some information.
Comparable jackets do NOT have the great qualities of this one. They don't have the great liner, or the hood. They're not finished as nicely.
It is fully lined—sleeves, hood, and body. (See sleeve roll up pic #7.) There are pockets on the outside as shown—and also inside. (See pics.) The liner is some sort of waterproof or water resistant fabric. The hood is not detachable. There are toggles and snaps throughout. I feel fairly confident that this is a vintage Black Mountain full zip tan, brown, and white jacket with a Moose pattern. It's very large:
Chest: 28.5 inches from armpit to armpit.
Length: 32 inches from top of zipper to bottom edge of garment.
Arm size from shoulder seam to wrist: 22" I can remeasure from mid back to wrist if you'd like.
Based on measurements, AI suggests this is a Men's XXL jacket. Please contact me with questions. No returns please. Continental US shipping only. The jacket will be lovingly packed and sent to you from a smoke-free home. Thank you.
