No, the outside zippered pocket is not waterproof, only splash-proof. For items you do not want to get wet, be sure to put it inside the dry bag, not in the outside zippered pocket.  Do not put any electronics in the outside zippered pocket. This additional storage is only meant to store for easy grab and go items that are okay to get wet, such as non-electronic keys, sunglasses, cards, etc. We also include a card with every order that reminds you not to store electronics in the outside zippered pocket.
