Winter teases us with sunshine in the morning, then pelts our afternoon bicycle commute with wind-driven snow. You can't decipher the rhythm, so come prepared. Our Shelled Synchilla Duckbill Cap is weather- and wind-resistant. Its bluesign approved nylon shell fabric is coated with polyurethane and treated with a DWR (durable water repellent) finish to block cold air, moisture and snow. Inside, warm Synchilla fleece traps heat, wicks moisture and feels comfortable against skin. A nylon duckbill brim keeps your face and eyes shaded from bright reflections and a back buckle customizes the fit.
