Why We Like It

Winner of Outside's 2016 Gear of the Year Award! Lofty, warm and light, the KSB 20˚ down sleeping bag is designed for three-season backpacking. 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.

Water Resistant: Outer fabric has a durable water repellant (DWR) treatment to protect the insulation from moisture that can impede thermal performance and add weight.

Durable Fabric: Light and tough 20D rip-stop nylon has a high strength-to-weight ratio to help resist tears without adding unnecessary ounces.

¾” Full-Length Zipper with Guard: Burly, but not bulky, the 3/4“ full length zipper has two-way sliders so it can be unzipped from top or bottom for ventilation. A full length zipper guard helps seal out drafts.
