Rothco Long Underpants ECWCS Level 2 'Warm Layer'

Thermal insulating long underpants for the cold days. The underpants are made of grid fleece, a type of fleece that is super practical for the active user. Grid fleece allows water vapor produced as a result of physical activity to escape from the body - it insulates heat and it allows sweat to be transported from your inner sweat-wicking layer. This allows sweat to spread over a larger area and evaporate, so you avoid getting wet and cold. The long johns work well with sweat-wicking layers, such as ECWCS level 1 Next-to-skin long johns. This way, you maintain sweat transport between the layers of your clothing. See also the corresponding Rothco ECWCS level 2 'warm layer' zipper neck top.
