Current Carry: Skookum Dog Citizen Canine prototype, Founder's Briefcase (every day carry), Small Cafe Bag (every day carry), Shop Bags (groceries, extra random stuff), Aeronaut 45 (travel), Synapse 19 (day hikes), Smart Alec (longer day hikes), Skookum Dog Road Duffel (Medium) (travel), Clear Organizer Wallet, Travel Stuff Sacks, Organizer Cubes
I am also able to fit a big plastic bag with night outfit which usually consists of 3 layers. which I think could fit in the size 4 Travel Stuff Sack.
For laundry and other heavy duty but lightweight hauling, a size 5 which would match the size of the original Large Pouches (the size of a letter size notepad) would be another size I would suggest.
Darcy, the pictures of the filled and labeled Travel Stuff Sacks placed in the Aeronaut are pure genius!
