Waterproof Phone Bag with Hand Strap and Airbag Float

The robust waterproofing technology is the core guarantee, safeguarding the storage functionality of the double-layered inner pockets. The bag body uses high-density TPU composite fabric, with an outer layer that is tear-resistant, a middle layer that provides strong water resistance, and an inner layer that is skin-friendly and won't scratch items. It is resistant to cracking and aging in high and low-temperature environments, capable of withstanding daily splashes and rain, as well as sea spray and short-term immersion in swimming pools.

The sealing details are meticulously designed: equipped with an airtight waterproof zipper, combined with a folded-edge Velcro closure at the opening to form a double seal. The closure is tight and smooth, and the folded edge prevents any water leakage. The high-end model even meets the IPX8 waterproof standard, remaining dry inside even after several hours of immersion at a depth of 1 meter. The seams use ultrasonic welding technology, replacing traditional needle and thread stitching, completely eliminating the risk of water leakage through needle holes.  Combined with a hidden zipper compartment design, it reduces friction between the zipper and the outside, ensuring both sealing performance and service life, allowing items in the double-layered inner pockets to be stored safely.
