On a climb up a high pass with a light pack, every ounce counts, and the Xenith Hooded Jacket is the lightweight down jacket that earns its place in the pack. Hexagon baffles hold 800 fill hydrophobic goose down in place for warmth at minimal weight and pack size. The 10D HELIUM fabric blocks wind, and its water-repellent finish sheds rain and snow. What Our Gearhead(R) Experts Are Saying:"On pre-dawn ski tours, I pulled the jacket on at each transition and the warmth felt even across my chest and shoulders right away. After a full day of hard movement, the hexagon baffles had kept the down where it started and the loft held up."
