    Excellent, but bulky

    I’m a side sleeper, and this is the perfect bag for it. The bag was a tight sqeeze in the bag compartment even after compression. Still, excellent bag.

    We enjoyed our sleeping bags thoroughly. They were very well insulated, but definitely work better with a sleeping pad or something similar on the bottom. Would rent again!
