Inner Cut & Sewn Expedition HOT Crew - Unisex. Purchased last winter on Amazon and worn once for an hour as an everyday inner layer. I intended to wear it as an inner layer for more formal clothing, but it was a bit too bulky and not quite what I was looking for, so I am selling it. Material Composition: Expedition Weight Kohden-shi (62% Acrylic, 25% Nylon, 12% Wool, 1% Polyurethane) Will ship on weekdays.
