The Kelty Cosmic Down 4 Degree sleeping bag is designed for cold-weather or year-round backpacking and camping. Lightweight hydrophobic DriDown fill and an array of features make the affordable Cosmic Down 4 Degree a real bargain.
The Cosmic Down 4 Degree sleeping bag is insulated with 550-fill power DriDown. Renowned for their efficiency in retaining heat and compressible properties the feathers and fibers of down have an incredibly soft comfortable feel and despite advances in synthetic materials continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet but the DriDown featured in the Cosmic Down 0 Degree bag performs differently. Employing a unique innovative polymer application DriDown actually creates a hydrophobic finish on each individual plume of down. This treatment results in insulation that stays dry up to 10 times longer and dries 33% faster should it become wet than that in bags with untreated down.
Box-baffle construction eliminates cold spots keeping outside air from reaching the interior of the Cosmic Down 4 Degree bag. A draft tube behind the 60" two-way locking zipper a fully-insulated draft collar and a contoured hood with an insulated hood baffle further enhance the thermal efficiency of the Cosmic Down 4 Degree bag. The hood utilizes Kelty's patented FatMan and Ribbon drawcords allowing you to adjust the top or lower sections of the hood by feel even when it's dark outside. A polyester taffeta liner provides internal comfort.
Other features found on the Cosmic Down 4 Degree include sleeping pad security loops internal liner loops and hanging loops.
