ERT™ PROTECTS AGAINTS BRAIN INJURIES
ERT™ (Energy Reduction Technology) incorporates advanced, soft polymers into helmets to help manage both rotational and linear impact energy. ERT pads mitigate impact energy through its unique material properties and refined geometry.
ERT™ comes standard in all Mad Hatter Helmets.
Why Traditional Helmet Testing Falls Short:
ASTM and CE helmet standards only test impacts at 300 Gs- the force needed to pass certification.
Research shows that concussions and traumatic brain injuries most often occur around 100 Gs, studies suggest up to 80% happen in this lower range- Well below what standard testing focuses on.
How ERT™ Improves Protection:
ERT™ (Energy Reduction Technology) is engineered to address these more common, lower-impact crashes. It helps manage and reduce energy during smaller impacts, where injuries are most likely- while ALSO delivering enhanced protection at higher G forces.
The result: broader protection for impacts riders experience most.
How Does ERT™ Compare to Other Leading Impact Systems?
ERT™ performance is proven in global third-party testing labs including Dynamic Research in Los Angeles, TASS in Holland and at the University of Strasbourg in France.
Overall, ERT demonstrated an 16% performance improvement in mitigating rotational impact and 29% improvement when compared to popular competitive energy management technology.


ERT (Energy Reduction Technology) incorporates soft advanced polymer pads into helmet designs to help manage both rotational and linear impact energy. ERT pads mitigate impact energy through both their unique material properties and their refined geometry.
Unlike most impact energy management materials, which do not deform and dissipate energy below a certain impact threshold, ERT responds instantly, even at low-impact levels commonly seen in many sports.
