This Waterproof Phone Pouch for Swimming perfectly solves waterproof problems such as outdoor humidity, seaside surfing, downboarding, and diving.
TPU composite fabric is used, seamlessly combined, and the most important thing is that it is equipped with IPX7 waterproof zipper, which makes the bag more secure and protects the items in the bag from drying.
Use scenarios: rainy weather, seaside, river, river tracing, surfing, paddle board, sailing, camping, etc.
Storage items: mobile phones, batteries, car keys, wallets, etc.
The design of the bag is transparent on both sides, which can control the mobile phone to the maximum extent, and can be used normally in the rain, making your outdoor sports safer.
