The Swift Cap is an ambassador and customer favorite, utilizing bluesign® approved, lightweight and breathable fabrics to deliver a performance cap for trail running, hiking, or any warm weather active pursuit. The Swift Cap features a recycled nylon blend that's highly breathable, water resistant, quick drying, and delivers UPF 40 sun protection for warm weather trail running and hiking. Its shaped brim and nylon panels protect the face and eyes from the sun, and its low profile fits nicely under a helmet for alpine climbing and ski touring. And weighing only 2.5 ounces, it's ideal for the ounce-counting backpacker and thru-hiker. The dark fabric under the brim helps reduce glare, while mesh panels ensure superior breathability. A quick-release back buckle allows for on-the-fly adjustment, and the moisture-wicking TransAction headband keeps perspiration off the face and eyes. A breathable, lightweight, and water-resistant hat that will keep them cool and comfortable in the summer heat, the Swift Cap is an excellent choice for active warm weather wear. Swift Cap
