First, a little about myself. Iím just over five feet tall, and I tell people that even though I have a ďwarm heart,Ē Iím ďcold natured.Ē By which I mean I tend to be cold even when other people are warm. So, having told you that, Iíll now tell you about this sleeping bag. I found it quite snug and cozy for someone of my height. If youíre 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. Iíve used it on three trips, and as long as the night-time temps stayed from above freezing to around 50, it was greatónice and snug! Iíd also recommend that you get a sleeping pad to put under itóthat will help keep you warmer too. Pros: The ďstuffableĒ pillow is greatóI stuffed it with my down-filled jacket and had a great nightís sleep. The bag also really keeps out the wind. Cons: Too heavy to carry on long camping trips (although itís not bad at all for walk-in sites). Kind of hard to get it back into the sack when youíre packing up. But I like this bag a lot and would recommend it.
