Why are the fabric specifications used for the backpack's body, bottom, and front pocket different from each other?
Hegiorsak configured the fabric specifications differently according to the use of the body that bears the weight of the load, the bottom that experiences frequent friction, and the front pocket that needs to maintain its shape.
The force and friction applied to each part that makes contact when putting down the backpack or packing gear are different. Hegiorsak's Ultra Cube 55 backpack distributes three fabric specifications according to the use of each part.
