Ouch, those look nice.I'm pretty sure I have a hat lined in this. Well, really a reversible bucket hat, but I usually wear the other, Epic cloth side outwards. I like the fabric. It'd make some very warm and sturdy pants imo. Fairly thick, spongy,breathable fabric, basically a woolen flannel. The color in the pic is true. It's more of a dark charcoal than a mid grey. The pattern is very subtle.
