Landen Bwrote a review of Sierra Designs Cloud 800 Sleeping Bag: 35 Degree Down on February 5, 2019
Familiarity: I've put it through the wringer
Love this bag. It is exactly what I thought I was getting. The zipperless design is innovative and intuitive, and the sleeping pad sleeve keeps me in place throughout the night. I’m usually hot, so the foot vent gets used quite often. I also appreciate that the bottom isn’t insulated, as that helps keep this bag so light.
