Adding to cart… The item has been added

The Sky Pond mummy sleeping bag is designed for when weight and compressibility matter just as much as warmth and comfort. Using only premier, synthetic fill, the bag also features a cinchable hood to keep heat in on cold nights. Slumberjack’s fuss-free, double-sliding zippers make it easy to get in and out of the bag – because we know nothing is more frustrating than a zipper that snags. Backpacking or car camping, this sleeping bag is great for getting a good night’s sleep.
