First, a little about myself. Im just over five feet tall, and I tell people that even though I have a warm heart, Im cold natured. By which I mean I tend to be cold even when other people are warm. So, having told you that, Ill now tell you about this sleeping bag. I found it quite snug and cozy for someone of my height. If youre taller than me, you may want to consider ordering the longer version. Also, in my opinion the bag should not be rated for temperatures as cold as zero degrees Fahrenheit. Ive used it on three trips, and as long as the night-time temps stayed from above freezing to around 50, it was greatnice and snug! Id also recommend that you get a sleeping pad to put under itthat will help keep you warmer too. Pros: The stuffable pillow is greatI stuffed it with my down-filled jacket and had a great nights sleep. The bag also really keeps out the wind. Cons: Too heavy to carry on long camping trips (although its not bad at all for walk-in sites). Kind of hard to get it back into the sack when youre packing up. But I like this bag a lot and would recommend it.
