Big Agnes Dream Island 20° Doublewide

The Dream Island 20° Doublewide is a 2-person synthetic sleeping bag rated to 20°F, weighing 3090 g and insulated with Fireline Max Eco synthetic fill rather than down — more tolerant of damp conditions but heavier for the same warmth than a down-filled equivalent would be. A Pad Cinch System keeps two sleeping pads from sliding apart underneath the bag overnight, and the top layer zips off completely to double as a standalone comforter around camp. The rectangular cut prioritises shared space over a snug, weight-saving mummy shape. At 3090 g (roughly 1545 g per person), this is a car-camping or base-camp bag rather than one to carry on a trek — its weight only makes sense when it's riding in a vehicle rather than a backpack.
