We always just use a couple small dry bags, (roll down top), We have one for a first aid kit and fire starting ect., One slightly larger one for camera gear bug dope tp sunscreen, lunch, and one for the chew and flask. We simply leave them all clipped into the canoe when we portage, things are organized so you dont have to dig through a big bag to find stuff and its waterproof and easy to carry. Just clip them to the thwarts.
