Made from Smartwool's sustainably sourced Merino 250 fabric, the Thermal Merino Reversible Cuffed Beanie insulates and moves moisture to help keep you comfortable from sunrise to sunset. And the reversible pattern gives you twice the style. With an adjustable ear band for more or less heat and clean seams for a no-bulk fit, it's a do-anything essential, all season long.
