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.
| HAT SIZE | INCHES | CENTIMETERS | HELMET SIZE |
| 5 1/2 - 6 1/4 | 18" - 20" | 46 - 50 | SMALL |
| 6 1/4 - 7 | 20" - 22" | 50 - 56 | MEDIUM |
| 7 - 7 5/8 | 22" - 24" | 56 - 61 | LARGE |
| 7 5/8 - 9 | 24" - 26" | 61 - 66 | X-LARGE |
*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.
