Double Layered Inner Pocket Waterproof Phone Bag

For daily commutes, you need to balance phone protection and small item storage; for outdoor leisure, you need to withstand water and dust intrusion; and for waterside activities, you need to protect your valuables – the cross-body waterproof phone bag is based on "portability + protection," and the addition of a double-layer inner pocket design precisely addresses the core pain point of "difficulties in categorized storage." It deeply integrates the advantages of "unrestricted cross-body wear and robust waterproofing" with "double-layer partitioning and meticulous storage," both securing your belongings and organizing your personal items. It becomes an essential item for various travel scenarios, making every trip effortless and organized.

The robust waterproofing technology is the core guarantee, safeguarding the storage function of the double-layer inner pocket. The bag body uses high-density TPU composite fabric; the outer layer is tear-resistant, the middle layer provides strong water resistance, and the inner layer is skin-friendly and won't scratch items. It is not prone to cracking or aging in high and low-temperature environments, and can withstand daily splashes and rain, as well as seaside waves and short-term immersion in swimming pools. The sealing details are top-notch: it features an airtight waterproof zipper, combined with a folded-edge Velcro closure at the opening for double sealing. The closure is tight and smooth, and the folded edge prevents water leakage. The high-end model even reaches 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, balancing sealing performance and service life, allowing items in the double-layer inner pocket to be stored safely.

The double-layer inner pocket design is the core highlight that distinguishes this waterproof bag from ordinary models, achieving an advanced level of storage efficiency. The internal compartments are clearly defined, with the main compartment serving as a dedicated phone pocket, equipped with shock-absorbing foam lining to securely hold large-screen phones (even with thick cases). This effectively prevents scratches from keys, coins, and other hard objects.  The outer side of the phone compartment uses high-transparency TPU material and a special conductive film, boasting a light transmittance of over 95%.  Sliding to unlock, typing, scanning for payments, and taking photos can all be done without delay, without needing to remove the phone, maximizing convenience. The secondary compartment is a multi-functional storage area, with added mesh pockets and small hidden compartments for organized storage of keys, earphones, access cards, cash, and other small items, easily accessible without searching. Some models also feature a water-resistant secondary compartment, protecting valuables such as documents and cash even if a small amount of moisture seeps into the main compartment. Furthermore, the bag's capacity is designed with specific uses in mind: the daily commute version is 2-3L, holding only essentials without being bulky; the outdoor version is around 5L, accommodating a power bank and sunscreen, and some models even include a dry/wet separation compartment for storing swimsuits and wet towels, preventing odors and cross-contamination.
