Sorry to spam this forum with a ton of threads....but I'm excited right now =) Weeeee!
Well, after playing with it a little bit, I've come to the conclusion that the big agnes encampment 15 degree long with it's huge inflatable pad is not going to work in here. It's just too bulky. Now I've had too many bad experiences with down so I'm a synthetic man myself and I'm planning on sleeping in the cold with this thing (I'm a new englander so I'll be camping in the whites)....maybe picking up the supershelter attachment.
Which lightweight synthetic bag works well in the HH....with consideration of occasionally having to pitch it like a bivvy bag?
