Prospects for the future development of bulletproof vests

Comfortable design
Comfort, as an important indicator of bulletproof vests, can be improved through more ergonomic design to enhance its comfort and flexibility, which is beneficial for various tactical movements and movements. For example, a bulletproof vest shoulder strap of the US military adopts a clear trapezoidal design, with the front connection point of the strap leaning towards the midline of the body, and the neck also needs to leave the shoulder socket for traditional shoulder support. At the same time, redundant design is retained to ensure that the shoulder strap can cooperate with upper limb activities and better match different shoulder shapes of different people.  
lightweight design
The development towards lightweight bulletproof is also one of the future trends. The bulletproof layer has changed the traditional practice of stacking bulletproof fabrics layer by layer, and is designed in a three-dimensional manner based on the trajectory and state of the projectile. For example, a flexible human body armor from the United States has a thinner thickness and a 13% reduction in weight, which undoubtedly reduces the physical exertion of soldiers and is more conducive to the completion of tactical movements.
Modular design
Adopting modular structural design to enhance the functional integration of bulletproof vests. The method of integrating bulletproof vests and carrying equipment not only reduces the number of varieties, but also reduces the burden on individual soldiers and avoids the problem of functional duplication, truly achieving the integration of carrying and defense, multi-purpose or multi-functional wearing. The modularity of portable equipment can be simply described as a universal accessory package connection system. The wide variety of accessory packages provides soldiers with more options for sub packages and components, making it convenient for them to flexibly configure and layout various equipment and weapons and ammunition according to mission needs. It also makes individual equipment more systematic and adaptable to different mission environments. The AVS modular combat system allows for the replacement of every component like a building block, with the option to freely choose between a protective backplate and a restraint strap to support the backpack. In addition, different equipment can be selected according to different tasks, such as heavy vests required for assault and protection. To achieve long-distance penetration, a lightweight vest is needed for quick deployment and strategic maneuvering.
