I am a pretty big fan of North Face and it is their bags like this that has made me one. I bought this from Moosejaw online about a month ago. I have been out 2 different weekends already with this bad. One weekend it was 55+ and the other it was 30+. Both weekends I was nice and comfortable! It is not overwhelming when it is warmer out, but also kept me warm in the 30's. It is pretty light too and comes with a nice small bag for packing. I have 4 sleeping bags and was super happy to see that the bottom of the sack is labeled with the bag type. This helps me grab and go from my massive closet of gear. Def would recommend this bag!
