With an exceptional fit and heat-trapping warmth, the Columbia Alpine Action Beanie is designed to keep you comfortable during dynamic activity in the cold. This high-performance beanie is crafted from cozy, breathable 100% acrylic knit fabric, with plush microfleece at the ear band to help seal out the cold. Omni-Wick technology pulls moisture away from the body so sweat can evaporate quickly. Made from smooth 100% polyester interlock fabric, the Omni-Heat thermal reflective lining utilizes little silver dots to reflect and retain body heat and help regulate body temperature. Imported. One size fits most.
