Smartwool The Lid Thermal Beanie - Charcoal Heather, Size M

Cold ears and sweaty foreheads ruin a good winter run. The Smartwool The Lid beanie solves both problems with a single layer of 100% Merino wool that regulates temperature, wicks moisture, and resists odor. The snug, low-profile fit slips easily under a helmet or hood, making it a versatile companion for everything from ski tours to city commutes.
