This liner is tightly quilted. The closer the width of the seams the warmer it will keep you. The width of this great liner is about an inch. It is olive drab. The sleeves and interior are made of soft cotton. It has buttons to attach to a parka. Our company is a wholesale distributor as well. We have many fashion retailers that stock this jacket. They rip out the sleeves and use it as a fashion vest. Because you don't see this kind of quilting anymore, it is very different looking and fashionable.
