Big Agnes Greystone 0 Sleeping Bag


Packable For Freezing Treks

The Big Agnes Greystone 0 Sleeping Bag is surprisingly light and packable for how warm it feels. Its lofty down insulation packs small for an easier time on the trail, and Big Agnes treated the down for hydrophobic protection to help the down stay lofty after it gets wet. Big Agnes built the ripstop shell and taffeta lining out of 100% recycled polyester, and they both have DWR treatments for extra water protection. The Greystone features a close-fitting hood with draft tubes around the collar and down the full-zip for a solid seal from cold night breezes. You can attach cotton or wool liners inside, and you can pair this left-handed version with a Women’s Greystone’s right-handed version. Big Agnes included stuff and storage sacks for compact packability on the trail and airing out at home.
