The NCC is a dramatic improvement on the sleeping bags of old. Comfort is integrated into the dual element structure, which prevents the bag from "spinning" and allows superior insulation. The integrated self-inflating mattress unfolds instantly. The underside of the mattress features an anti-puncture material which is twice as resistant to puncture as the market average and the cloth interior feels just like cotton. This innovative design gives consumers the comfort of home in a sleeping bag.
