Weighed up my items,
and my winter 0* bag rolls to the 5Lb 6oz mark, and the pack, empty is 4lbs 15oz. so basically 10.5 lbs with the bag and the pack, this is starting to seem heavier than i'd like, but we'll see how it all goes in.

My sleeping bag does fit in that lower compartment, so i have the whole upper to store stuff in, i also have the option of zipping the divider between the two open...
