1, taste
Real Swiss army knife backpacks have almost no special chemical smell, while imitations are usually accompanied by strong smell due to different materials, which is more likely to damage health.
2. Weight
Authentic Swiss army knife backpack is light and comfortable to carry. Imitation material is much heavier than the real thing, because it needs to be treated with many harmful chemicals to increase its firmness.
3. Inside
Authentic bags are designed with special key chains, pencil cases, folders and headphone cable sockets. At the same time, the inner lining of the bag is also printed with Wenger's logo. Many fake bags are not available or extremely rough.
4. Delivery system
Authentic bags are designed with multi-panel comfortable carrying system, which greatly reduces the carrying pressure, and has a padded shoulder pad design, which will not be soft when pinched by hand and has good breathability. Fakes are just rough sponges, which can easily stick to clothes after a long time.
5. Waterproof design
Genuine R bags have passed the strict 20-liter water-repellent test. The use of bulletproof nylon cloth originated in the United States. The first lining used in automobile tires and military bulletproof vests has been studied and improved for a long time. Because of its strong organization, wear resistance and tear resistance, this kind of cloth has several times higher wear resistance than ordinary nylon cloth, polyester cloth or cotton cloth.
