Rothco Thermal undershirt ECWCS level 1 'Next-tokin'

Out of the extensive ECWCS (Extented Cold Weather Clothing System) you get the most important layer of all - the innermost. The silky smooth inner layer effectively wicks sweat away from your skin, spreading it across the surface of the fabric and allowing it to be absorbed by the next layer you wear. In addition to being sweat-wicking, the fabric is woven so that moisture can evaporate easily through the fabric without being 'trapped' in the material. This undershirt can be combined with the Rothco ECWCS level 2 'warm layer' zipper neck top for effective sweat transport and thermal insulation in cold temperatures. See the corresponding long underpants.
