Serious protection that's seriously light

The best-selling Swift Cap from Outdoor Research is for more than just training, it provides UPF 50+ sun protection on the crown of your head and a full mesh liner for superior ventilation in warm weather. The Swift Cap packs in function and performance thanks to its breathability, water resistance, and quick-drying construction. Its shaped brim and nylon panels offer serious cover from the sun for runners and hikers, and its low profile fits nicely under a helmet for climbers and ski tours. Plus, weighing in at only 2.5 ounces, it’s ideal for the ounce-counting backpacker and thru-hiker.
