To determine whether a travel bag is good or not, it is necessary to have a scientific carrying system, loading system, fabric selection, and breathable and sweat wicking design from several aspects.
1. Backpack system: The backpack backpack system consists of a back plate, shoulder straps, chest straps, and waist belt, which is used to support the entire backpack. A good backpack can evenly disperse the weight of the backpack. Shoulder straps, waist cushions, and chest straps play an important fixing role and must be adjustable. Different adjustments can be made according to individual body shape to better secure and reduce friction. In addition, the contact area between the shoulder strap and the inner side of the belt should be soft and elastic, effectively reducing the upper and lower friction of the shoulder strap or belt from elastic vibration. The chest strap not only needs to be adjustable in length, but also should have its fixed point on the strap set as a sliding track for easy adjustment to a comfortable position for individuals.
2. Fabric. Generally, cycling bags are made of PU coated nylon fabric with waterproof, anti dry knot, wear-resistant, and tear resistant properties. The durability of a backpack is mainly determined by the fabric.
3. Designed with a ventilation, breathable and sweat wicking system. When cycling, the backpack is fully buckled onto the back, and if the back is not ventilated and sticky sweat covers the back during cycling, it will be quite uncomfortable.
4. Is the loading system reasonable. A backpack usually consists of a main bag, side bag, accessory bag, etc. Cycling bags are usually made in small sizes, usually not exceeding 30L, usually 10L, 14L, 18L, 20L, 25L, etc. So, through the design of the bags in each part of the backpack, it is possible to better allocate items, make reasonable use of capacity, and of course, more importantly, facilitate retrieval.
