If it’s one thing Wisconsin winters have taught us, it’s that staying warm starts with a good base layer. Our Thermaskin™ Heat Turtleneck not only provides an extra bit of warmth, it’s super soft and comfortable too. Its high-performance fabric* actually generates heat by absorbing body moisture. It also wicks perspiration away from your skin, which is crucial for comfort in cold weather. *Heat technology is guaranteed for approximately 30 washes.
