Ballistic Vest Size Guide

When it comes to ballistic vests, a proper fit is defined by parameters like chest size, waist size, and length of the vest. Read on to know what you should consider!

Chest Size

To get to know your chest size, begin by measuring your chest at its widest position, generally underneath the armpits. Ensure that the tape is snug on your chest, but not very tight. After you have taken the measurement, match it to the Hard Shell sizing chart to find your vest size.

Waist Size

Similar to how you measure your chest size, measure your waistline with tape around the area where you normally wear a belt. Then, match it with the Hard Shell sizing chart to ensure that the vest fits securely around your torso.


In the case of the vest’s length, you need to select the size so that the vest protects essential organs without compromising mobility for any sort of activity. Based on this, you can refer to the Hard Shell size chart for ballistic vests. 


In addition to these specifications, you also need to be mindful of how you want to utilize the vest. If you need additional customization options in the form of adjustable straps or modular attachments, it must also be considered.

Helmet Size Guide

A well-fitting helmet becomes very important when it comes to head protection. Here are a few things that you need to consider!

Head Circumference 

The helmet size is determined by the measurement of the diameter of your head just above your brows and ears. Once you have got this measurement, you can refer to the Hard Shell sizing chart to make the right purchase.

Forehead Exposure

Ensure that the helmet is neither too high nor too low on your forehead. A right-fitting helmet will not make your forehead overly exposed. Also, the ridge of the brow should not be covered and vision, eyewear, or other gear should not be impaired by the brim of the helmet. This will maximize protection without blocking your vision or hindering movement. To achieve this fit, adjust the helmet straps as needed.

Neck Strap

Neck strap

The helmet’s neck strap should have a snug fit at the nape of the neck, comfortably below the ears, ensuring that it stays in the right position during unexpected movements or collisions. If you are experiencing any irritation or chafing, it could suggest an incorrect fit.

Chin Strap

Similar to the neck strap, the chin strap should be adjusted to maximize comfort. It should fit snugly against your chin without obstructing breathing or movement.

Pad Strap

Many helmets come with adjustable cushioning inserts that can help you customize the fit. Based on how the helmet fits on your head, you might require a thicker or thinner pad set. You can experiment with various pad designs to get a snug and comfortable fit.
