Carrying system: a backpack is a piece of equipment that is carried on the back and bears a certain weight.Reasonable bearing system can effectively decompose the pressure of weight on the body, reduce fatigue and protect the body from injury.The shoulder system is usually made up of shoulder straps, belts, and chest straps.
The parts of the shoulder belt that are in contact with the body are required to be soft, breathable and load-bearing. The tightness of the shoulder strap and belt can be adjusted freely. A typical backpack has a force ring or belt on both shoulder straps, which can be pulled by hand to reduce the pressure on the shoulder or back of the backpack.
Because many cycling backpacks can be used for multiple purposes, they have a similar structure, but we Strongly recommend: When riding, don't leave your hands and hook the force ring (belt), because it is very dangerous. At present, many backpacks have a shoulder strap structure that can be adjusted at will to adapt to different heights of backpackers. The role of the chest strap is to connect the two shoulder straps on the chest to ensure a stable back and even force.

The ventilation structure is mainly through a mesh lattice and back contact, and there is also a large gap between the mesh and the backpack, so that the sweat on the back is easily removed with the air during exercise. One structure is a breathable structure, and there is a special foam material in the contact portion between the backpack and the back, which has good perspiration wicking property. Basically, it can keep your back dry.

Water bag: There is now a water bag suitable for cycling and hiking. It is placed inside the backpack and extends from the tube to the mouth. It can ensure that the user can drink water at any time and any place. Many riding bags or more The use bag has a structure for installing water bags. There are eye-catching signs on the backpack. Different brands of backpacks have different signs, some are blue big water drops, some are a dripping faucet.
Waterproof structure: People have joys and sorrows, and there are unexpected events.
