You might be new to the trail, but a great nights sleep is an old habit you have no intention of ditching. Designed for optimal thermal efficiency, the Middle Mountain is a PFC-free mummy bag made from recycled materials for a sustainable sleeping system that doesnt skimp on comfort when camping off the grid. Stay warm and dry even in cool, damp conditions with SierraLoft synthetic insulation and a DWR-treated shell, and cinch in the heat around your head with its adjustable hood. Convenient details like an anti-snag zipper, internal stash pocket for nighttime essentials and the included compression sack are sure to keep your backpacking goals and dreams within reach at all times.![]()
