I currently have a Nemo Tempo 20 bag that I use when cool weather camping that's good for me down into the twenties.  I have merino wool long underwear that I sleep in and am usually very comfortable.  I have been hammock camping and open the bag up like a quilt and that seems to work very well.  I've been looking to replace it with a quilt specifically to save weight and space.  Hoping not to spark a bag -vs- quilt discussion but get some info on a good, small and lightweight quilt that will cover me (6'2", 290+/-, very wide shoulders) and keep me warm without breaking the bank.
