Nemo Disco Mens 30 Sleeping Bag Sleep Like You Actually Sleep Most people sleep on their side, yet most bags are cut like a mummy. The Disco solves that problem with the Classic Spoon(TM) shape: a generous cut at the elbows and knees that lets you shift positions through the night without fighting the bag. It's a three-season backpacking bag that packs down small, so you're not paying a weight penalty for the extra comfort. The Thermo Gill(TM) chest vents give you precise temperature control without letting cold air in, and the Blanket Fold(TM) draft collar seals the neckline without the constriction of a traditional collar. A waterproof/breathable footbox keeps condensation from sneaking in at the foot end. If you've ever woken up stiff from wrestling a too-tight bag all night, this is the fix.
