Every Seer Helmet is manufactured with permanent size and Date of Manufacture (DOM) markings. The helmet size is indented into the black ABS plastic inner shell and is located at the top-center rear of the helmet. The DOM is heat stamped into the leather and is located on right-hand, inner surface of the helmet harness. If you need help locating the size or DOM on your helmet, please contact Super Seer.


With safety being the #1 factor, it is our policy that all helmets should be replaced between 2 and 3 years. This recommendation is based off the Motorcycle Safety Foundation report on helmets. The Motorcycle Safety foundation suggests, “Replacing any helmet that has been dropped onto a hard concrete surface, regardless of no obvious damage. Helmets will deteriorate over a period of time. The MSF suggests "replacing helmets three years old, regardless of how new they appear." Additional information can be found at Based upon recommendations by California Highway Patrol and the extensive duty use of a motor helmet, the maximum life of a Police motorcycle helmet is 3 years with 2 years the recommended replacement interval for departments. Other factors affecting helmet life to consider are daily use, heat and humidity environments. As in any petro-chemical product the resins become brittle with age as the molecules migrate out of the material. This affects the elasticity, changing the impact and energy absorption capabilities of the helmet. Because of these and other factors, we strongly recommend replacing any helmet every three years.
