Emily wrote a review of Kelty Light Year XP Sleeping Bag: 40 Degree Synthetic on June 24, 2010
This has kept me warm through three seasons in New Hampshire (I tried it once in a cabin in the winter and was cold all night). It's light and compresses well. My favourite feature is the foot zipper. It's great to be able to vent heat in the summer and you can walk around a bit with this on if it's cold and you don't want to get out of the bag.
