"What Our Gearhead® Experts Are Saying:""I wore this through a full week of fishing in humid conditions and the HeiQ Pure odor control made a noticeable difference by day three. The DWR finish shed light rain and spray without the brim getting waterlogged, and the low crown sits comfortably under a hood when the weather turns.""Long days on the water and sweaty approaches through summer heat demand a hat that handles moisture as well as it handles the sun. The Patagonia Merganzer Hat is built for exactly those days, combining a DWR-treated recycled nylon crown that sheds light rain and spray with a moisture-wicking recycled polyester headband that keeps sweat from building up through sustained effort. At just 2. 45 ounces the low crown sits close to the head without adding noticeable weight or bulk to the kit. miDori bioSoft treatment in the headband keeps the fabric soft and comfortable against skin through full days of wear, while HeiQ Pure odor control technology handles the inevitable funk that comes with hard use in warm conditions. The slightly curved brim cuts glare on bright water and open terrain, and the floating EVA foam brim stays structured even after repeated exposure to rain and sweat. Built from bluesign approved recycled materials throughout, the Merganzer Hat is a hat worth wearing every day and feeling good about."
