Product Overview
Cold-weather layering needs to account for both warmth and the sweat generated while you're moving. The Rothco ECWCS Gen III Mid-Weight Underwear Top (Level II) addresses both with breathable grid fleece and moisture-wicking fabric. This long-sleeve thermal base layer fits into a cold-weather clothing setup for airsoft games, hiking, camping, and other outdoor activities where you need insulation beneath your outer layers.
Mid-weight fleece with stretch and moisture control
The soft polyester/spandex blend combines the warmth of grid fleece with flexibility for active movement. Its waffle-style construction provides mid-weight insulation, while the breathable fabric allows moisture to move through the layer. Rather than leaving perspiration against your skin, the material wicks it outward to support drying—a useful feature when field movement or a steady uphill walk starts to generate heat.
Anti-microbial and anti-odor properties add another useful element for active wear. These features help manage odor during use, making the top well suited to a day spent moving between physical activity and quieter periods outdoors.
Coverage that works with your movements
The zip collar lets you adjust the neckline to suit your layering needs. Wear it open for a less enclosed feel, or zip it up into a turtleneck configuration for additional neck coverage in the cold. That adjustment is convenient when you want to change coverage without removing the entire shirt.
An extended back tail adds coverage when you crouch, bend, or reach. For airsoft players, that is particularly relevant when lowering behind cover or moving through uneven terrain. Thumb holes help hold the sleeves in position, including when you're pulling another garment over the top, so there is less need to readjust them as you layer up.
