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. Newest to our line is the Super UL Vapor 15, with a 25-inch zipper to save weight, a 15d shell and lining, and 850-fill down for warmth and compressibility. To save even more weight for medium-to-small users, it comes in three sizes.
