How to Choose a Bike Backpack?
The quality of a cycling backpack can be analyzed from two perspectives. From a scientific perspective, a cycling backpack must have a carrying system, loading system, fabric selection, and breathable and sweat-wicking design.
From the perspective of outdoor cycling needs, backpack accessories need to include important factors such as water bag outlet, sleeping bag compartment, rain cover, helmet fixing equipment, etc.
The backpack carrying system consists of a back plate, shoulder straps, chest straps, and waist belt, which is used to support the entire backpack. A good backpack system can evenly distribute the weight borne by the backpack. Shoulder straps, waist cushions, and chest straps can 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 area where the shoulder strap and belt come into contact with the skin on the inside should be soft and elastic, effectively changing the upper and lower friction of the shoulder strap or belt to elastic vibration.
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 6L, 12L, 18L, 20L, 25L, etc. The design of the bags in each part of the backpack allows for better allocation of items, reasonable utilization of capacity, and of course, more importantly, easy access.
Generally, cycling bags are made of PU coated nylon fabric (such as PU coated 450D polyester, 210D nylon), which is waterproof, anti dry knot, wear-resistant, and tear resistant. The durability of a backpack is mainly determined by the fabric, and I think everyone doesn't want the backpack to be stretched out halfway through the ride.
When cycling, the backpack is fastened to the back. If the back is not ventilated and sticky sweat covers the back during cycling, it is quite uncomfortable. A mesh resin board has been added to the cycling backpack to isolate the back from the backpack body. A good cycling bag features a 3D breathable mesh design on the inside of the shoulder straps and waist cushions, giving air a flowing space and effectively keeping the body in contact dry.
