About Sierra Designs
Sierra Designs has been one of the most renowned outdoor brands in the industry since 1965. Not only are Sierra's products reliable enough to help thrill seekers like Eric Larsen summit Mt. Everest and journey to both the North and South Poles, but they promote a harmonious relationship with the environment we play in as well. The editors of Outside Magazine, National Geographic, and Backpacker Magazine have all presented Sierra with numerous gear awards. Sierra is headquartered in Boulder, Colorado. We challenge traditional thinking by incorporating partial Flex construction into these bags, making them more comfortable and more thermally efficient. Ergonomically shaped foot boxes and ultralight foot box venting may seem like subtle details, until you climb on in – and experience the most comfortable sleep you’ve ever had in the backcountry.
