We're happy to announce that the fifth prototype for our North Rim sleeping bag series is complete.
In this latest design, we've enhanced the signature features and versatility of the North Rim series to create a bag that is useful in a wide range of temperatures but maintains the light weight and low bulk that keep it in step with long-distance backpacking ethos.
The bag is still being tested in Yosemite National Park and on the Pacific Crest Trail, but preliminary data suggest that it will be comfortable to 30°F. It weighs just 23.5 oz. (1 lb. 7.5 oz., or 667 g). The insulation in the sleeping bag is PrimaLoft One, and the lightweight 1.1-oz. ripstop nylon is water repellent and durable.
