Thank you for viewing. This is a Montbell Down Hugger 800 FP #3, right zip. It's the final model of the older type, but it's said to have a lower temperature rating than the current model, and less down clumping. A woman used it about five times for stays in mountain huts. I personally believe that the stretchability to allow you to sit cross-legged while inside the sleeping bag, along with the 800 fill power's lightness and heat retention, are what make it the No. 1 sleeping bag. - Brand: mont-bell - Model Name: Down Hugger 800 #3 - Temperature Rating (Comfort): 3°C / 37°F - Temperature Rating (Limit): -2°C / 28°F - Extreme Temperature: -19°C / -1°F - Features: SUPER SPIRAL-STRETCH SYSTEM - Down Type: Goose Down - Fill Power: 800 FP Thank you.
