Biking in the cold just got more comfortable: our Stovepipe cap protects against brutal windchill with a stretchy wind-proof shell fabric on the top and front. A soft Merino wool-blend fabric over the ears and on the back wicks moisture and helps regulate body temperature. The low-cut front covers the forehead, eliminating the cold gap between your eyewear and helmet. - Wind-blocking panels - Merino wool-blend lining for moisture-wicking - Long cut protects ears, neck, and forehead - Integrated eyewear slots - 3-panel design fits perfectly under helmets - 0°F (-18°C) TO 25°F (-4°C) COMFORT
