For our long backpack trips, we want an option with wicking, quick-drying performance that can go a few days without offending our tentmates. That's where the ExOfficio Give-N-Go Full Cut Briefs come in. These active-ready undies have a full cut that covers buns and hips with a breathable, stretchy fabric that dries quickly, and is finished with an odor-resistant treatment to keep things fresh after long days.
