I can make something cheap for a summer TQ and BQ. Most people think of a 3 season as spring, summer and fall. I think winter is most important so I have always tried to think in terms of my winter bag being fall, winter, and spring bag. I am ready to transition from a sleeping bag but can only afford one. So, is a 0 TQ to much at 60?
Dont think about this question in terms of weight. Just temps.
