I'm going to be section hiking the AT next summer and need to decide on a sleeping bag. I had first looked at the Sierra Designs Backcountry being that I'm 6'2, 225lbs and twist and turn a lot when sleeping. After seeing that this sleeping bag weighed in at 2lbs 11oz someone told me that I might want to look at bags from Western Mountaineering. Looking for anyone using the MegaLite or Caribou MF and their thoughts on them. Thanks!
