Hydrogen 30 Sleeping Bag (850 Down)

The new curved baffles on this bag reduce shifting of the down, allowing this bag to provide enough warmth for cool weather climbs and backcountry excursions a new easy access, fold down second zipper allows easy ventilation. At just a pound and a half, this bag puts the ultra in ultralight.
