I just ordered 1 belt-pack auto/manual inflatable PFD and 1 vest auto/manual inflatable PFD from Cabela's. Gotta say, love the belt pack! It stays out of the way. I got the belt-pack for myself, and the vest for my fishing buddy and any other passengers. However, we're both big guys and the vest is really small and uncomfortable. I'm tempted to return the vest for a belt-pack, but my fishing buddy cannot swim. And I know the belt pack's when inflated require a person to lift the tube over their head. Is the belt-pack still a safe bet for a non-swimmer? I don't want to put him in danger if he does fall overboard fumbling trying to put the tube over his head and drown while doing it.
