The material process of backpacks

The backpack is used in special environment, and the material and process of backpacking are high.All the position of the backpack force is sewn back to the stitching three times to make the stress position strong and durable.Backpacks of buckles and other components can be used to prevent the frost, the damage and the 120 degree deformation is not damaged.

Because the backpack is used in a special environment, the material and process of backpacking have been put forward higher requirements.All the position of the backpack force is sewn back to the stitching three times to make the stress position strong and durable.Backpacks of buckles and other components can be used to prevent the frost, the damage and the 120 degree deformation is not damaged.Backpack is main 420 d nylon Oxford, 1000 d nylon, 600 d and 600 dpolyester (polyester), or 1000 d CORDURA materials.1000D material density is high, very wear-resisting, suitable for use in the wild.CORDURA is an upscale wear-resistant nylon roving fabric.The abrasion of the material is much higher than the general nylon or polyester, and the weight is light.More than 90 percent of the world's famous brands use this prestigious nylon material.These materials can withstand water pressure of 0.5m~2m to keep the inside of the bag dry.Some of the material also has the tear - proof function, once the puncture is broken, the broken mouth will not open the expansion.
