A 3-layer Cap. The outside is a gray twist of Wool Ragg, a tough fabric with great insulating properties, even if it gets wet. Next to your head is a soft, lightweight Acrylic fiber which wicks perspiration out of your hair. In the middle is man-made fiber, Gore-Tex, a waterproof, breathable membrane that lets water out into the wool layer, but not inside to make your head chilly. 100% Wool Outer Shell, 100% Acrylic liner with Gore-Tex middle layer. |
