The Patagonia Beanie Hat has clean lines and an adaptable fabric combination making it the perfect companion to warm up on a chilly morning. It uses a lightweight, compressible 2-layer construction that features a moisture-wicking polyester blend and chlorine-free merino wool that is responsibly sourced from the grasslands of Patagonia. This combo provides all-day, no-itch comfort and warmth, along with a polyester band inside which adds fast wicking and next-to-skin comfort.
