The soft and friendly inner polyester fleece liner on the Patagonia Powder Town Headband wicks moisture and dries quickly to keep you from getting sweaty or overheated. This two layer knit headband gives you just the right amount of protection for keeping your ears from getting nippy without the added coverage of a full hat when you’re working out, whether you’re cross country skiing, breaking a snowshoe trail, or headed up into the high country where the winds are making your ears uncomfortable. What can we say? This is designed to keep you cool in the cold while protecting those tender ears!
