I had a little NSV on my recent camping trip. Now I imagine there might be times when it would be fun to have two people in the same sleeping bag. But when that second person is under your own skin, it is not so fun. The last time I used my sleeping bag was in 2011 and I fit in it much like an oversized pillow in a small pillow case. This past weekend I could not believe how much room I had in that bag. I could maneuver around, toss and turn without getting the sleeping bag all twisted and turned. Not having that extra 150 pounds of person in that bag makes a world of difference.
