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 40° Mummy Sleeping Bag improves on past designs to provide a 3-season superstar. Lightweight, warm responsibly-sourced 550-fill-power down in the innovative trapezoidal baffle construction delivers maximum thermal efficiency, keeping you warm down to 40°F. A durable water-repellent (DWR) finish ensure this Kelty mummy bag maximizes your protection from the elements. A zip-close internal stash pocket houses your headlamp, cell phone, and other essentials. The soft, smooth, durable 20-denier 100% nylon shell holds up again and again, and the natural-fit, spacious footbox provides more room to wiggle your toes. 100% polyester liner. Includes stuff sack for quick departures. Imported.
