Dry bag for water activities. Are you often outdoors? This bag is waterproof and made of PVC with a water-repellent silicone coating. It closes with a zip closure, keeping the contents completely dry inside. It is particularly suitable for small items like smartphones or wallets. Note: Do not store sharp objects in the bag, as they may damage it. The smartphone cannot be operated while in the bag. Check that the dry bag is completely closed before fully submerging it in water with the smartphone inside. Test for waterproofing before each use with a dry towel inside the bag to ensure it is sealed during complete submersion.
