Oregon Aero® Zeta-C® Universal Upgrade Kit

Zeta-C UpgradeThe Oregon Aero® Zeta-C® Universal Upgrade Kit fits a wide range of helmets and other types of protective headgear. The innovative upgrade kit includes everything you need to make occupational and recreational headgear pain-free, dramatically more stable and cooler.


The Zeta-C® Upgrade eliminates painful pressure points and “hot spots” by equalizing the load throughout the headgear’s existing cushioning or suspension system. The kit’s three pads are custom-designed from a temperature- and pressure-sensitive composite material that molds itself to your head and improves stability. The pads’ self-wicking proprietary fabric promotes evaporation of sweat, creating cooler, drier headgear.

It is called the “Universal Upgrade Kit” because it can be used to upgrade most types of protective headgear. 

Once the Zeta-C® Universal Upgrade Kit is installed, you will forget that it’s there, but you will remember the headgear’s dramatically improved comfort and stability. With headgear pain eliminated, you can focus on the task at hand.
