I compare my backpacking cost to nights at a hotel. For the price of 3 nights at a med price hotel you get an outstanding bag. I have slept down to 25 degrees and was very comfortable. Very lights and also comforting to know that it is waterproof. Some reviews complain about the stuff sack but I have found it works find to roll the bag up best you can, put it in the bag, and then push the remaining bag into the stuff sack - works fine. Calculate how much you have invested in backpacking stuff then divide it by the nights you plan on using it and it gives you a value equation.
