Aloksak make really great waterproof to 200 metres snaplock bags. This one is even big enough to put your rifle in (great for canoeing/boating/hunting trips. It is the only waterproof gun bag I know of. Of course the smaller ones are great for your phone, camera etc: http://www.survival-pax.com/aLOKSAK-Bags-Extra-Large.html
