This is a military jacket with an alpaca-blend fleece lining. - Color: Gray - Material: Fleece lining, 70% wool, 30% alpaca - Design: Inner zipper, button closure Thank you for viewing. This is a popular Cootie deck jacket. It's incredibly warm because it uses 30% alpaca wool, which is known as the "gem of the Andes" for its high heat retention. I live in a heavy snowfall area, and the temperature drops below freezing every day in winter, but I don't feel cold at all in this jacket. I can even wear just a T-shirt underneath. In fact, I get hot when I move around. Furthermore, it has stenciling on the chest and back, which looks cool. The dark gray fabric with blackish stenciling is hard to see from a distance, which is a nice touch as it's not too overbearing. I think it's also good for riding a motorcycle. The neck and hem can be tightened, providing even better cold protection. It's thick, so it has a substantial weight and a sense of luxury. It has a unique worn look (like the honeycomb pattern on denim), giving it a cool, vintage feel. I'm selling it because it no longer fits me due to muscle training.
