| Not sure how small of one you could find, but you could look into dry bags. We use a couple for supplies, snacks, when we take diabetic kids white water rafting. I would imagine that they make them in many different sizes.
If it's not going to be submerged (just occasionally splashed or whatever) then go with the ziploc, and double bag it just in case of rips or tears.
