Some standup paddlers and racers wear inflatable pfd's belts. Regulations say Inflatable pfd's must be worn and not stowed and use a pull cord to inflate.
Self-inflating pfd's used in sailing are generally a bad idea as they are going to inflate when submerged then you are stuck trying to paddle with a horse collar around your neck.
Never heard of self inflating dry bags, most people try to get air OUT of their dry bags to take up less space . Maybe you mean flotation bags?
