The US Army OG-108 is a vintage, heavy-duty wool-blend field shirt (or shirt-jacket) in olive drab green, often used as cold-weather gear from the 1950s through the 1970s. Key features include an 80-90% wool flannel construction, buttoned chest pockets, and a button-front, typically made of wool and nylon. It is widely considered an excellent, durable, and warm vintage utility garment.
