Backpack material technology

Backpacks are used in specialized environments, which means there are high requirements for the materials and construction processes. All critical stress points on the backpack are sewn three times using a sewing machine with a backstitch, ensuring they are sturdy and durable. The buckles and other components of the backpack can withstand freezing, impact, and deformation at temperatures up to 120 degrees Celsius without sustaining damage.

The outer materials of the backpacks primarily include 420D Oxford nylon, 1000D nylon, 600D or 1000D polyester, or 1000D CORDURA fabric. The 1000D material is highly dense and extremely wear-resistant, making it ideal for outdoor use. CORDURA is a renowned high-grade, wear-resistant nylon fabric developed by DuPont in the United States. The abrasion resistance of this material far exceeds that of regular nylon or polyester, while being lightweight. Over 90% of backpacks from leading global brands use this prestigious nylon material.

These materials can withstand water pressure of 0.5 to 2 meters, keeping the contents of the bag dry. Some of these materials also feature tear-resistant properties, so if punctured, the tear will not spread.
