Mysse is the ultimate headwear for expeditions. A functional cap that protects your head and ears from cold winds and water, and your eyes from sun and water and everything in between. This hat is a favourite that keeps your head warm throughout your adventure with both style and function. The Mysse 3.0 is made with a 3-layer construction from bio-based nylon and is lined with wool polyester, which helps to retain heat and makes the cap quick drying.
