1. Material Advantages: PU (polyurethane) material looks close to genuine leather, has a good simulated leather feel, and is more affordable. It is wear-resistant, aging-resistant, easy to care for, and has a certain degree of waterproof performance, suitable for daily use in a variety of environments. 2. Diverse Designs: PU chest bag designs keep up with fashion trends and have a variety of styles, including simple and modern Korean style, sports and leisure, and business retro, to meet different occasions and individual needs. 3. Strong Functionality: Many PU chest bags are designed with USB charging ports, which are convenient for users to charge electronic devices while walking or traveling. In addition, the internal structure is reasonably designed, with multiple pockets, which can effectively store mobile phones, wallets, keys, cards and other personal belongings, keeping the items in order. 4. Lightweight and comfortable: Compared with traditional backpacks, chest bags are small in size and light in weight, which reduces the burden on the shoulders and neck when carrying, and are especially suitable for short-distance travel, cycling, sports or daily commuting. 5. High Durability: Although PU is not genuine leather, it has high folding resistance and can withstand multiple bends at room temperature without cracking, ensuring the service life of the chest bag. 【Specifications】
