As an overnight backpacking guide in Yosemite, I’ve learned the difference between agony and bliss in the backcountry boils down to practicality and reliability of my trail gear—most specifically when it comes down to clothes. Since backpacking is a minimalist venture, my wardrobe usually consists of one specialized outfit I can rely on to keep me warm, dry, and otherwise comfortable for days on end in the elements. This is the trail gear that comes with me on every trip.

1. Outdoor Research Juneau Beanie

This no-frills, feather-light beanie hasn’t stretched out or worn through after a year and a half of hard use. Its design was inspired by Alaskan fisherman—hence its name—and for a head sock that only weighs 2.3 ounces, its insulation value is ample. Winter or summer, it’s a staple in my pack when the temps drop after sundown.
