Remember the trapezoid from 10th-grade geometry? Turns out, this funky shape provides the ideal solution for helping sleeping-bag baffles retain heat. The Kelty® Cosmic Down 20° Short Mummy Sleeping Bag improves on Kelty sleeping bags to provide a 3-season superstar. Lightweight and warm 550-fill-power down in the innovative trapezoidal baffle construction delivers maximum thermal efficiency. Environmentally-friendly fabrics with a CO- and PFC-free durable water-repellent (DWR) finish ensures this Kelty mummy sleeping bag helps the environment and your confidence. A zip, internal stash pocket houses your headlamp, cell phone, or other essentials. The soft, smooth, durable 20-denier nylon shell fabric holds up again and again, and the natural-fit, spacious footbox provides more room to wiggle your toes. Zipper draft tube with anti-snag zipper design allows for easier entry and exit. Dual slider for ventilation with locking zippers. Includes stuff sack for quick departures. 100% polyester liner. Imported.
