The Sherpa Khumjung 2.5 Layer Pant gives you the gift of dry legs. After all, if youâ€™re going to keep your torso covered, why ignore the other half of your body? The Khumjungs make it effortless. The elasticated waistband expands to slide over whatever youâ€™re already wearing, and the knees are anatomically constructed for ease of movement. The waterproof, windproof, and breathable ripstop nylon fabric does the rest of the work for you.
