Introduction to Yufeng Bag Industry's Backpack Bag:

A backpack is a package used to carry personal items, usually made of materials such as cloth, leather, nylon, etc. The main types of backpacks include large backpacks, medium backpacks, and small backpacks, which have different capacities and functions and are suitable for different scenarios and needs. Large backpacks are typically used for long-distance travel and outdoor adventures, with a capacity of over 50 liters and multiple compartments and pockets inside for easy sorting and storage of items. The medium-sized backpack is suitable for short distance travel and urban life, with a capacity between 30-50 liters, a simple design, and easy to carry and use. A small backpack is suitable for daily use, with a capacity of less than 30 liters, lightweight, compact, and convenient to carry.

The material and craftsmanship of backpacks also have high requirements, requiring waterproof, wear-resistant, lightweight and other characteristics. Modern backpacks usually use high-tech materials such as nylon and polyester fibers, which have excellent waterproof performance, wear resistance, and portability. The backpack's carrying system, loading system, and external system have also been carefully designed to improve comfort and convenience.
