If Wisconsin winters have taught us one thing, it s that staying warm starts with a good base layer. Our Thermaskin Heat Turtleneck base layer not only provides an extra bit of warmth, but it s also designed to be super soft and comfortable, ensuring you feel cozy all day. Its high-performance fabric actually helps generate heat by absorbing body moisture. It also wicks perspiration away from your skin, which is crucial for comfort in cold weather. It s long enough to tuck into pants or jeans, ensuring your cozy stays secure all day..
