For example, in the picture below of GSG9 special police officers performing missions, looking at a pile of excellent equipment on their upper body, but wearing jeans on their lower body, does it feel like they are "acting" at first glance? How do they fight in this outfit?

After all, those who wear jeans know that although it is wear-resistant, it has little elasticity and can be quite restrained when moving.
Why is GSG9 still wearing it? That's because although they wear jeans like you, what you're wearing is called casual jeans, while what they're wearing is tactical jeans.
The difference between the two is that although they look the same, they use many designs that are not visible on the surface.
For example, fabrics need to further improve their wear resistance while also having greater elasticity. And in terms of cutting, it should also be able to meet the needs of large movements such as kicking. In addition, it also has high-tech functions such as anti-static and anti water splashing.
In this way, special police officers can engage in combat without having to go back to the police station to change their pants in case of emergencies.
When not performing tasks, tactical jeans can also be worn like casual jeans. These hidden designs and functions used for combat are more comfortable and free to wear in daily sports and outdoor scenes than regular casual jeans.
This is the uniqueness of tactical clothing.
