The Kaibab is our twenty-degree workhorse. Whether your passion is hiking, hunting, or camping, this three-season sleeping bag gives you the versatility you need to be comfortable in a variety of temperatures and environments. The Kaibab capitalizes on the superior weight to insulation ratio of 850+ fill power premium goose down to cut weight but not warmth. The dimensions of our standard cut mummy bags provide you with sleep system ergonomics that achieve the perfect balance of comfort and weight. A YKK zipper, coupled with a full down draft tube and draft collar, seal out the cold.
