You can put sunglasses, mobile phones, wallets, water, watches, charging treasures, pens, books, clean clothes, flashlights, etc. inside it. ◆[Durable and Waterproof]: The outside of this folding backpack is scratch-resistant, strong and durable. Normal backpacks only have waterproof fabric. However, this mobile backpack not only has waterproof fabric, but also its zipper.

You can carry it in your hand, put it in your pocket, or put it in your suitcase. For example, at the airport, if your luggage is too fat, you can take this storage knapsack out of your suitcase, and then take out some items from your overweight suitcase and put them into this knapsack. This way you can share some of the weight of your trunk and avoid gaining weight.★ ◆[Practical]: This portable backpack is suitable for outdoor sports. There are many small meshes on the shoulder straps, which improves breathability. The length of the shoulder straps can also be adjusted freely. When climbing, you arrive at the mountainside and want to start exploring, but you don't want to carry around a heavy backpack, so change this ultra-lightweight backpack and put the things you need in it to start a comfortable travel experience.★ ◆[Other services]: If you have any quality problems during use, please contact us.
