User Review: Western Mountaineering Puma Super MF
Fill: 850 plus down
Temperature Rating: neg. 10 farenheight
Weight: 3.5 pounds
Price Paid: $450
I purchased this bag to replace a Wiggy Ultima Thule, which I froze in at 20f (above zero). This past year we spent 12 nights in temperatures that ranged from 15 above to 6 below zero. I used this bag and was too warm until the temperature dropped to below zero. I would highly recommend this bag to anyone interested in a lightweight super warm sleeping bag.
The only drawback that I could see with this bag is the lightweight materials used for the shell, which I feel should be a bit more durable. Western Mountaineering told me that the shell is very durable and will last for many years.
