I ended up ordering a Sea To Summit and Granite Gear for myself but actually found two new old stock/clearance Salsa bags for my wife's bike frame bag/top loader bar bag.
The top loader should work out well for my wife's narrower bars with just her sleeping bag and under quilt. She does longer trips with me but we do hotels when we go together, super stoked for this as it will be her first camping bike trip. Its going to be on the C&O/GAP...pretty much zero elevation other than a couple short detours and running in and out of towns. We are going in April so keeping the gear dry and mud on the C&O are really the only things worth thinking about.
thanks again, honestly still surprised that so many tent, hammock, bag, stuff sack brands do not give packed measurements and only focus on volume and weight.
