Sierra Designs: Sierra Designs is revolutionizing the way people sleep in the outdoors. In the past few seasons they have introduced the wildly popular Flex and Stretch bags that allow for sleeping in different positions and provide more room for unrestricted movement. With ThermoSpectrum dryDown expedition bag you can purchase one bag that will adjust to the changing temperatures encountered when going from base camp to summit. They have a removable insulated top layer that is also highly water resistant and breathable. Unlike any other expedition bag, this new design adds insulation to the outside of the bag allowing the added layer to retain its loft. It also provides the ability to add insulation with down sweaters and other available layers. You can completely remove the zip off top for warmer temperatures and it also allows for better ventilation and escape route for moisture. The bags are available in men's and women's designs in three temperature ratings ranging from -40 to +20.
