>>1718137I just got a Big Agnes Summit Park bag
It's a big down bag that saves on weight and size by not insulating beneath you and instead integrating your insulated sleeping pad into a thin stretchy pocket.
haven't had a chance to use it overnight but on my living room floor it was giant and comfy.
the fact that it is giant and drapes around you means that its still about the same weight and size packed as a smaller mummy bag with wrap around insulation. I got it for just over $200
