The helmet is one of the oldest protective gear that goes back to the 23rd century BC. Modern ballistic helmets have lighter yet sturdier materials, such as carbon fiber, Kevlar, and high-impact resistant plastic. 

Innovative designs aim to provide a high-performing and efficient solution for combative activities, including military and law enforcement operations.


When looking for a tactical helmet, it is critical to understand that what you purchase can protect you from harm. It should have undergone thorough testing and has a design that can meet the US military or NIJ standards. 

Here are three top characteristics that you should consider when choosing your Tactical Helmet.


If your helmet sits too low on your head, the tendency to block your field of vision is high. It can impede your eyewear's effectiveness and might even be the cause of lowered agility in a combat field.

Typically, shell head measurement comes in four sizes: small (S), medium (M), large (L), and extra-large (XL). These sizes can vary by brand and maker, they generally equate to:

S = 21in - 22 1/2in (53 - 55cm)

M = 22in - 23 1/2in (55 - 58cm)

L = 23in - 24 1/2in (58 - 61cm)

XL = 24in - 25 1/4in (61 - 63cm)

However, you should always check with the manufacturer to be certain about the helmet you're interested in. 

Here is a step-by-step guideline that you can follow to know what helmet size is correct for you.

  1. Sit in an upright position.
  2. Have your comrade measure your head length. Let your comrade start in the middle of the brows to the back of your head. You can use a caliper (preferred) or a tape measure. Record the measurements.
  3. The next step is to determine the measurement of your head width. Do it by getting the widest length between the left and right side of the skull. Let your comrade position the caliper or tape measure just above your ears. Again, do not forget to record your measurements.
  4. Now, get your maximum head circumference and record the measurement. Remember that you are sitting in an upright position. It is best to take the measurement just above the bony brow ridges while passing the tape measure just above the ears.
  5. You can check with helmet brands on the best recommendation of helmet size based on your measurements,


If your tactical helmet sits too high, the risk of it being unstable is high. A loose-fit helmet can be a nuisance and can cause you annoyance than can lower your focus.

Remember that a low focus can cause you harm or even your life on a battlefield. It means stability is a critical factor in choosing your tactical or Military Helmet.

The question is: How can you check if the fit is appropriate for you? Here are some indicators for you to take note of:

  1. Tactical helmets typically have a four-point chin strap/ belt. Tighten the belt and check if the helmet feels snug, but not too tight and not too loose.
  2. Check if the helmet’s crown pad reaches the top of your head.
  3. Look above using your eyes without tilting your head up. You should see the rim of your helmet. If you can see the inside of your helmet, the helmet might be too low and loose. If you can’t see the rim, the helmet might be too small for you that makes it sit too high on your head.
  4. Your tactical helmet must remain in place when you move your head from side to side or shake your head. 
  5. Ask a comrade to assess if your helmet is stable. He should see that the front rim is approximately half an inch on top of the eyebrows. 


The wearer should feel comfortable while using a ballistic helmet. A good one will not hamper your performance and can even boost its wearer’s protection and safety, especially during combat.


Before you choose and purchase a ballistic helmet, you have to know and understand why there are various types of helmets and what you should look for when picking one. Here are some tips that you should keep in mind:

  • Assess and check the protection level of the helmet. It should have undergone rigorous testing as per the NIJ standards.
  • The tactical helmet that you will select must have padding, a suspension, and a harness system, which are the fundamental components of a protective helmet. 
  • The tactical helmet should be made of high-quality materials that make it sturdy and long-lasting.
