How do Body Armor Works? Basic Guide 

Armor has been worn since ancient times, and over the years, it has become very advanced. Earlier, people used plants and animal parts around their bodies to protect themselves in the wild. As time went by, metal plates were used in battle, and today it has become highly sophisticated.

If you have been searching for armor, you would have found a range of protection that comes in different styles, weights, shaps, protection levels, sizes, etc. Ever since the advancement in weapons such as bullets, cannons, etc., bulletproof vests have become prevalent in many countries.

Before we move on to how body armor works, let us discuss a bit more about the different armors in the market.

Know the Materials 

The most common types of armor in the market are soft armor and hard armor, which offer different benefits to an individual. The most common soft armor you will find in the market is kevlar which is lightweight and easy to move. Kevlar fibers are also interlaced with other fabrics or materials to improve protection against attacks. 

When it comes down to hard armor, these are considered more effective than soft armor because they are thicker and often made from more robust materials. While kevlar can be worn throughout the day, hard armor is much more tactical and should be worn only when in need. 

It is simply because they often consist of metal or ceramic plates, which are heavy and far more superior. Manufacturers today use several types of materials to make the armor more advanced to stop much higher ballistic weapons. 

In any case, you must do your research and shop for armors that fit your needs. 

How Does it Work?

When a bullet hits a surface gives out energy that allows it to penetrate anything that comes its way. When you wear body armor, a simple energy transfer gets spread and deforms the bullet. The armor completely absorbs the bullet and does not let it penetrate through the armor plates. 

Body armor plates are often made of materials that are strong, stick and have a high density. Along with this, you will also find plates and armor coated with additional materials such as resin that can stop a bullet or projectile. 

Each layer of the woven material in the armor absorbs the bullet’s force, and each layer works together to stop the bullet completely. Keep in mind that you will still have some impact as a wearer, but it reduces the chances of severe or deadly injury. 

The more layers of ballistic materials present in your armor, the fewer chances you get injured. Body armor comes in different shapes and sizes, affecting mobility, so if you are looking for one, make sure they fit you well. 

When Should You Replace Your Body Armor?

Like most things in the world, you must understand that your armor is not built to last. This means that you should replace your armor after a specific time period so that your vest can protect you. Secondly, if your vest is damaged due to a bullet or projectile, make sure that you change your vest at the earliest. 

According to The National Institute of Justice (NJI), individuals who own body armor must inspect their vest every 2-to-3 years. And as a general rule, the old armor should be replaced after five years. 


Owning body armor can be an excellent option for you, especially in the army or police. However, civilians have the right to buy body armor for their protection.
