The Beanie Hat's clean lines and adaptable fabric combination make it the perfect companion to warm up on a chilly morning of bouldering or slide under a helmet or hood on the slopes. The lightweight, compressible 2-layer construction features a moisture-wicking blend of 55% polyester and 45% fine-gauge, chlorine-free merino wool from the grasslands of Patagonia. This combo provides all-day, no-itch comfort and warmth. A polyester band inside adds fast wicking and next-to-skin comfort. Fabric is bluesign approved.
