For the price and performance, I don't think this sleeping bag can be beat, especially if you are looking for maximum warmth in severe cold camping conditions. The lining is very smooth and surprisingly comfortable, while also adding the benefit of providing a degree of water/weather resistance. Likewise, there is a generous amount of insulation that is fitted well in the sleeping bag so that it does not shift or clump up, keeping the whole bag evenly insulated.Other features such as the "zipper plow" make it a breeze to zip/unzip the bag which just further adds to how much value there is to this bag. The only "drawback" to this bag is that it is fairly large and bulky; if you are a backpack camper trying to find lightweight performance, this is not it. For my purposes though, this is basically perfect!
