Description

The Atom’s ultra-light design and our highest quality down have given it cult status among alpinists as a bivvy bag on extreme climbs, but its comfortable, silky fabric make it a great bag for warm-weather bivvies on casual summer road trips as well. Updated with our Down Defender treatment offering an extra level of moisture protection for sleeping bags exposed to wet environments.
