I've been training for the Appalachian Trail for some time now, and I just can't seem to get the right sleeping bag. This bag works wonders when it comes to being light-weight and it compacts very well, but like all Lafuma sleeping bags, I was not entirely happy in the warmth department. I have a tendency to turn a lot in my sleep, and the bag did fairly well with keeping me warm, but my biggest complaint was in the bottom of the bag. Needless to say, my toes were freezing on both occasions when sleeping in the bag, and the temps weren't even in the 30s.

Just tested this bag in an unheated room in my house. Temp got to 55 degrees or so and i had on shorts and a t-shirt and was very cold! Will be returning and will try the Mountain Hardwear Ultralamina 32 Sleeping Bag as it is getting very good reviews. I wanted this bag to be my 3 season bag because I own a -20 bag that is awesome. I cannot imagine that this bag will keep me warm at any temps below 50.

This bag is very light, and can compact in the stuff sack to about 5x5x5". Both the internal and external shell fabric are water RESISTANT, and most moisture will bead off if it's not pooling, this bag will retain your body heat if it does get wet throughout your trip. Hang dry for a couple hours in the sun in the morning and it should be good. Although it's listed as max user height 6', I believe Lafuma bags run a bit longer; I am 6'3" and fit comfortably lengthwise but this is a rather narrow sleeping bag; nice for retaining heat, not so much if you turn in your sleep. Good choice for fastpacking and sleeping under the stars.

also, the color scheme I received was similar to the other x series sleeping bag with a grey main bag and an orange x.
