A hidden USB charging interface is designed on the outside of the bag body, which is connected with a mobile power supply (self-provided), so that you can charge your mobile phone, headphones and other devices while walking, and you don't have to worry about the battery of your mobile phone when riding or traveling!
Main bag+front zipper bag+inner secret bag+certificate compartment, which can easily store personal belongings such as mobile phones, wallets, keys, charging treasures and cards.
Anti-theft design: the hidden bag close to the body can store important documents or cash, which is more secure against pickpocketing.
Adjustable non-slip shoulder strap (the length is suitable for different body types of men and women), which fits the chest or waist, does not tighten the shoulders for a long time, and can be stable and not shake when running or riding.
Breathable material: high-density nylon fabric with breathable back pad, which is not stuffy after long-term wear.
