Best winter bag i have owned - Western Mountaineering Bristlecone MF -10 Sleeping Bag

I ordered this after an attempted camping trip over Thanksgiving. It was in Dollly Sods WV and it was very cold and windy the first night. I woke up shivering and could not get warm. We cut the trip short. When I got home, I started my search for a truly warm winter bag. I have always been on the edge of comfort on the winter trips, and decided it was time to pay the money and get a warm winter bag.
I have not had a chance to try this out yet. Upon unpacking it, it instantly became very puffed up. It is amazing how big it becomes and yet is so light. I am impressed with the heavier strip inside the zipper which prevents the zipper from snagging on the softer inner & outer fabric. This is an excellent design. It was also one of the features that swayed me from a similar bag that had negative reviews about the zipper getting caught. I love the amount of room in the bag. I have always disliked mummy style bags due to the restricted nature of their size. I am looking forward to getting out soon to test my comfort in this bag. Bottom line is that if I get cold in this bag, there is something wrong with me and I have to give up winter camping.
