Two pair of drysuit socks, in very good used condition. One pair is 3 mm thick neoprene or similar material, marked as size "L" and are snug but useable on a men's size 13 foot. The second pair is made of a fleece material about 5mm thick before any compression. They have a flat bottom and fit a men's size 13 foot well for length with extra room for width. This pair has no size markings.
