Because the backpack is used in a special environment, higher requirements are placed on the materials and craftsmanship of the backpack.
All the stressed positions of the backpack are stitched three times with stitches to make the stressed positions firm and durable. The buckle and other parts of the backpack can be made anti-freezing, anti-smashing and deformation at 120 degrees Celsius without damage.
The outer materials of the backpack are mainly 420D Oxford nylon, 1000D nylon, 600D or 1000Dpolyester (polyester), or 1000D CORDURA and other materials.
The 1000D material has high density and is very wear-resistant, which is very suitable for use in the field.
CORDURA is a well-known high-grade wear-resistant nylon roving fabric developed by DuPont.
The wear resistance of this material is much higher than that of ordinary nylon or polyester, and it is light in weight.
More than 90% of the world's famous brand backpacks use this prestigious nylon material.
These materials can withstand 0.5m~2m of water pressure to keep the contents of the bag dry.
Some materials also have anti-tear function, once punctured, the rupture will not tear and expand.
