A two-season sleeping bag, the Disco 30 Regular is ideal for summer backpacking and camping trips. Filled with responsibly-sourced 650-fill down, the insulation has a PFC-free hydrophobic treatment to improve performance in damp conditions. Particularly good for side-sleepers, the Disco features a Classic Spoon shape. Generously cut at the elbows and knees, you can lie on your side without being constricted. A soft Blanket Fold collar gives a tucked-in feel for extra comfort. Nemo Disco 30 Reg Sleeping Bag - Spark/Fortress
