The NEMO Riff Endless Promise 30 Sleeping Bag combines sustainability and ultra-light packability to create an ideal bag for backpacking trips from the early days of spring until the first frost of fall. The Ultralight Spoon shape provides ample room around our knees and elbows for side sleeping, allowing us to roll in our sleep, and still manages to cut weight and space from the minimalist design. The bag is not only made from recycled materials but can also be entirely recycled at the end of its usable life, ensuring we minimize our consumption of finite natural resources.
