Duckbill Cap

What Our Gearhead® Experts Are Saying:

"I have been wearing this cap on trail runs and long hikes all season, and the mesh crown keeps airflow moving even on hot days when most hats turn into a sauna. The short brim folds flat into a jersey pocket or pack lid without losing its shape, and the DWR finish sheds light rain without soaking through."

Some caps are built for standing around looking good, and some are built for actually moving. The Patagonia Duckbill Cap falls decisively into the second category. Inspired by ultrarunning ambassadors and designed to perform across miles of trail, hot summit approaches, and everything that fills the hours in between, it keeps the head cool, the eyes shaded, and the whole setup as light and unobtrusive as possible. At just 1.5oz, it adds almost nothing to the equation while delivering the sun protection and airflow management that make a real difference across a long active day.

The front panel and brim are made from NetPlus recycled nylon faille sourced from post-consumer fishing nets, giving the cap a durable, moisture-shedding surface with a PFAS-free DWR finish that handles light rain and sweat without weighing it down. A fully recycled polyester mesh crown and back panel keeps airflow moving constantly so heat does not build up during hard efforts, while a lightweight recycled polyester sweatband wicks moisture away from the forehead before it becomes a distraction. The foam brim folds flat into a jacket pocket and rebounds to its original shape without any fuss, and the dark underbill cuts glare on bright days at altitude or on open water. Adjustable elastic closure at the rear dials in a snug, personalized fit across a wide range of head sizes, and the button-free crown sits cleanly under a helmet when the route demands it.
