To see if an Iron Man riding backpack is good, a scientific carrying system, loading system, fabric selection, and breathable and sweat-wicking design are must-haves.
Let's first analyze a good Iron Man riding backpack from the big aspects.
1. Carrying system: The carrying system consists of a backboard, shoulder straps, a chest belt and a waist belt. The backboard is used to support the entire backpack.
2. It is designed with ventilation and perspiration wicking system. When riding, the Iron Man riding backpack is completely buckled on the back. If the back is not ventilated during riding, it will be quite uncomfortable to cover the back with sticky sweat. A grid resin board is added to the backpack to isolate the back from the bag body.

3. Fabric. Generally, the Iron Man riding backpack is made of PU-coated nylon fabric (for example: PU-coated 450D polyester, 210D nylon), which is waterproof, anti-drying, wear-resistant, and tear-resistant. Whether a backpack is durable or not, the fabric is the main determinant.
4. Whether the loading system is reasonable. The Iron Man riding backpack usually consists of a main bag, a side bag, and an attached bag. Cycling backpacks will be made relatively small, generally no more than 30L, generally 10L, 14L, 18L, 20L, 25L, etc. Therefore, through the design of the bags in each part of the backpack, the objects can be better distributed, the capacity can be used reasonably, and of course, the most important thing is to facilitate access.
When buying, pay more attention to whether these key points of the Iron Man riding backpack are available. Choose the backpack brand, model and capacity according to your travel time, distance and items you bring.
