When you are wearing body armor, having the right fit is essential. If your body armor does not fit you properly, it will move around on your body and be uncomfortable. Moreover, it may also leave gaps from where bullets can penetrate your body.
So, how should your plate carrier vest or ballistic protection vest fit? Well, in simple words, it should be snug. It shouldn’t be too tight that it restricts your breathing and movement, and neither should it be too loose so that it moves and shifts around on your body. A good rule of thumb is that when you take a deep breath, and your chest expands, your vest or plate carrier should just start to feel tight.
Next up, it is also essential that your plate carrier vest or bulletproof vest covers all of your vital organs from the front and the back. Since soft armor can contort to the shape of your body, it offers a better fit and covers a larger area, however, it offers a lower level of protection. On the other hand, a plate carrier with a hard armor plate offers protection against bigger calibers, and it should ideally cover your chest from a couple of inches below your collarbone to a couple of inches above your belly button. You should also be able to hold an Isosceles pistol shooting stance, and shoulder a rifle without the sides of the body armor plates digging into your shoulders.
A plate carrier should have a snug fit, the back and front plate should be at the same level, and it shouldn’t sag forward under the weight of your tactical gear. When you are testing a plate carrier for the first time, make sure to move around a little after wearing it. Do some burpees and stretches to make sure that the plate carrier fits you, and doesn’t shift around.
