With technical fabrics and construction, 100% recycled, super-warm insulation, and tons of comfort features, these comfortable sleeping bags are designed to be lightweight enough for backpacking but cozy enough you'll want them in the campground too. The streamlined silhouette and Flow™ construction increase the thermal efficiency keeping you warm from head to toe.
