Having been the owner of a Wiggy's Hunter I really would like a lighter and more packable sleeping bag for sheep hunting and general backpack camping. I am a fairly large fellow at 275lb and 6'0 tall. Weight is of concern as is the pack size. Not planning the winter hunts with this bag per say, but rather the summer to mid September. Any recommendations on bags would be great. Want to explore my options before taking advantage of any Christmas sales deals.
