Lofty, warm and light, the KSB 20˚ down sleeping bag is designed for three-season adventuring. 
The 650 fill power down delivers exceptional warmth for its weight, is easily packed and provides years of use. 
A draft collar, over-stuffed foot box, insulated mummy hood and flexible baffles at the body’s core all work together to minimize heat loss for greater thermal efficiency. 
High tenacity fabrics are tough, light and comfortable. 
The expanded chest area and flexible baffles provide room to move, and a stash pocket keeps small items right at hand. 
Pair it with one of our Inertia or Static pads for a lightweight, packable backcountry sleep system.  

The KSB 20 Degree is insulated with 650-fill power white duck down. Renowned for their efficiency in retaining heat and compressible properties, down fibers 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 weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but Klymit equips the 20D rip-stop nylon shell with a durable water repellent treatment to help protect the insulation from moisture.

Flexible baffles are employed through three quarters of the bag to help cut down on weight and keep the insulation drawn close to your body to maximize thermal efficiency and allow you to move comfortably during the night. A three-quarter length zipper makes it easy to get in and out of the bag and a draft guard behind the zipper keeps cold air from creeping inside. A fully insulated hood and expanded chest area increases warmth and a contoured footbox provides comfortable space for your feet.

Available in your choice of color options, the Klymit KSB 20 Degree sleeping bag fits backpackers up to 6' 5" in height. A stuff sack is included that allows the bag to pack down to 13” x 8.5”.
