A 3-season synthetic bag for frigid nights

The Kelty Cosmic Synthetic 0 Sleeping Bag is the combination of the warmth of a three-season down bag and the lightweight feel of a summer bag, in perfect balance. This bag's CirroLoft insulation keeps bulk and weight to a minimum, while providing the same warmth that you might find a high-quality down bag. The mummy bag shape ensures you stay cozy, while the extra footroom prevents you from being too constricted.


The Cosmic Synthetic Bag's soft to the touch feel derives from its Nylon shell that also helps to protect it from the elements and usual dirt. The DWR used to help protect this bag is PFC-free and environmentally friendly. The Cosmic Synthetic 0 bag is great for cold weather, and even cosier with a comfort temperature rating around 18 degrees. This bag comes with its own stuff sack for easy packing and storage.
