The Big Agnes Park series bags are perfect for those of us who like a lot of room and don't like a confined space. Very well suited for larger people as well. They have no insulation on the bottom, just a sleeve to slide in a sleeping pad in. Most sleeping pads fit. I use Exped 9 LW and they fit perfect. Not having the bottom layer of insulation cuts down on weight and space; it also allows more insulation on the top layer. In cooler weather you'll need to use an insulated pad.
Both are 1 year old and used once each to test out. They are the most comfortable and roomy bags that I have ever owned.
