How to determine your CPD Ballistic Helmet Size

 

  • Using a cloth tape measure placed in the center of your forehead, measure all the way around your head.

  • Write down the result in inches or centimeters.

 

  • Use the sizing chart below, and convert your measurement to the nearest helmet size.

*In some cases helmet sizes will vary between the Seer S1602IV (Current) Riot Helmet and the Seer S1711 (New) Ballistic Helmet. For example:

  • An officer whose hat size is 7 1/4" would have worn a MEDIUM in the Seer S1602IV Riot Helmet. This officer will now wear a LARGE in the Seer S1711 Ballistic Helmet. However an officer whose hat size is 7" will wear a MEDIUM in both the Seer S1602IV and the Seer S1711.
  • An officer whose hat size is 6 3/4" would have worn a SMALL in the Seer S1602IV Riot Helmet. This officer will now wear a MEDIUM in the Seer S1711 Ballistic Helmet.
  • An officer whose hat size is 7 3/4" would have worn a LARGE in the Seer S1602IV Riot Helmet. This officer will now wear a X-LARGE in the Seer S1711 Ballistic Helmet.
