For long backpacking trips, we need a pair of wicking, quick-drying undies that can go a few days without offending our tent partners, and the Ex Officio Give-N-Go 2. 0 Full-Cut Briefs are among our top options. The full cut covers our buns and hips, while the stretchy fabric pulls sweat from our skin and air-dries quickly to help us wash as we go. Plus, an odor-resistant finish keeps us feeling fresh after long miles on the trail.
