1. Carrying system: The backpack carrying system consists of a backboard, a shoulder strap, a chest strap and a waistband, and the backboard is used to support the entire backpack. A good carry can evenly distribute the weight of the backpack. Shoulder straps, lumbar pads and chest straps play an important role in fixing. They must be adjustable. Different adjustments can be made according to different body types to better fix and reduce friction. In addition, the inner side of the shoulder strap and the waistband should be soft and elastic, and the upper and lower friction of the upper shoulder strap or the waistband can be effectively changed from elastic vibration. The chest strap does not only need to be adjustable in length, but also should be fixed on the chest strap as a slide rail for easy adjustment to a comfortable position. 2, fabrics. The general riding bag is made of PU coated nylon fabric (for example: PU coated 450D polyester, 210D nylon), which has the functions of waterproofing, anti-drying, abrasion resistance and tear resistance. Whether a backpack is durable or not, fabric is the main deciding factor. I don’t think everyone wants to encounter half of the trip and the backpack is broken.
3, there is a ventilation, ventilation and perspiration system design. When riding, the backpack is buckled on the back. If the back is not ventilated during riding, the sticky sweat will be quite uncomfortable on the back. The backpack adds a grid of resin plates to isolate the back and the body. Ward's riding bag features a 3D breathable mesh design on the inside of the shoulder strap and waist pad, giving the air a flowing space to effectively keep the body contact dry.
4. Is the loading system reasonable? The backpack usually has a main bag, a side bag, and a bag. Cycling bags will be made smaller, generally no more than 30L, generally 10L, 14L, 18L, 20L, 25L and so on. Therefore, through the design of the bag parts of the backpack, the objects can be better distributed, the capacity is rationally utilized, and of course, it is more convenient to take.
