It is heavier and warmer than most other cold gear fabrics on the market today. This material wicks very well via the physical property of capillary action. It features a two layer fabric construction that is smooth on the outside and brushed on the inside which draws moisture up and away off your skin to the outside layer where in turn is then spread over a wider surface area until it naturally evaporates on its own. The result creates a buffer zone of warm and dry air next to your body.
