what size would be good for: 2, 0 degree synthetic bag one long and one regular, each to go in their own compression sacks. also have a north face rock 32 tent with footprint what size for that one?
you don't need the compression sacs if you're using these. I would say use the large to be on the safe side for the long 0 degree. Even if you have a little extra room, you synch down the bag and would be pretty much the same size of a medium. If you packing the poles with your tent, measure the length of the poles and get the sac accordingly. They sacs are all pretty wide so most tents should fit in them dependant on length
