This stretchy winter beanie hat fits most men and women, sizing that accommodulates a wide range of head shapes for a snug, custom fit that is neither too tight nor too loose. Crafted from a blend of 30% merino wool and 70% acrylic with a soft polyester fleece inner lining, it delivers superior warmth by trapping heat close to your head while wicking away excess moisture to keep you dry and comfortable. Merino wool s natural moisture-wicking and odor-resistant properties help maintain freshness during active use, as the breathable fabric pulls sweat away from your skin better than most other fibers. Available sizes: Medium-Large, X-Large-xx-Large. Available colors: Black, Light Grey, Wine.
