I bought this sleeping bag for an archery elk hunt this year with my wife. Temperatures during the trip dipped well below freezing and we were very comfortable and warm. The features we both liked is the roomy nature of the bag, the head covering when it gets cold, and the zippers on each side. I like how the bag wraps around the sleeping pads making it feel more like a bed than being wrapped up. I could easily move around and slept very well. We paired this bag with two 3.5-inch insulated sleeping pads that we had purchased years ago. We decided this was a great product and helped make a week in the mountains very enjoyable.
