Jason W.wrote a review of Western Mountaineering Puma Super MF Sleeping Bag: -25 Degree Down on January 9, 2012
Backcountry overnight in Yosemite last week, temps in low teens, elevation 7000ft, bag was toasty warm, material is silky smooth. Im just over 6 ft, 215lbs and the reg bag sized perfectly. Zipper worked smoothly and draft collar functioned well. The loft on this bag is amazing and it compresses well when packed down into the stuff sack.
