There are several kinds of hard armor. Some are made of metal, while others are made of ceramics or polyethylene PE. Alumina and silica are two popular choices, but if you’re on a budget, you may want to consider SiC ceramic plates. However, they are more expensive than alumina and polyethylene, and may not be appropriate for your budget. Boron carbide ceramic is also a popular choice, but it’s much heavier than SiC.
Soft body armor is generally lighter than hard armor. However, it’s less comfortable and can cause sweating if worn for extended periods. This type of armor is more expensive than soft body armor, and is not suitable for all kinds of outdoor activities. For these reasons, it’s best to use a hard vest only if you’re confident in your ability to withstand a fall. In addition to its reduced comfort, it can also make you feel hot.
There are several different types of hard armor available. Some are designed for specific types of jobs. Police wear soft armor, as they’re not likely to get into a shootout with a rifle. Other types of hard armor are designed for combat. These types of hard armor typically cover the nipples and back, which means they’re meant to protect the heart, lungs, and guts. While some styles of hard armor are designed to protect these parts of the body, they’re not designed for such tasks.
