User Review: Moonstone 650 Delta Morpheus
Fill: 650 + fill power goose down
Temperature Rating: 20 F
Weight: 2 lb, 14 oz.
This may be old news to backpacking experts, but comfort in the 20 degree F rating is not possible without an excellent sleeping pad underneath. Once you have that, comfort is possible. I have slept in this bag down to 15 degrees in windy conditions. Zipper can be hard to operate.
