  • The Technology

    This is the only sleeping bag in the world to feature Cross-Core, an industry-changing innovation that fuses NASA-developed aerogel technology with existing PrimaLoft Gold insulation, for more warmth without adding an ounce of weight. Sean McCoy, Managing Editor of GearJunkie.com had this to say: “Why is this a big deal? Well, aerogel is the lightest insulator on Earth.” It allows us to build a roomy, comfortable rectangular bag that's more than light enough to take backpacking.
