Atom Sleeping Bag


Size Guide

The Atom's ultra light design and high quality down have given it cult status among alpinists as a bivvy bag on extreme climbs. A great bag for warm-weather nights on casual summer road trips, the full update with changes like curved baffles that reduce shifting down and a fold-down second zipper for ventilation makes this bag even more comfortable than before.
