Who Are Rezon?

Home > About Us

Rezon is an advocate for the brain in sport. It challenges the notion that sporting performance is only below the neck, and offers groundbreaking solutions for protecting performance.

With Rezon, every design principle and decision is intentional. We work exclusively with the leading global experts in biomechanics, neuroscience, and the detection, diagnosis and provision of the latest treatments for brain conditions. As a B Corp, Rezon is part of a global community of businesses that meet high standards of social and environmental impact.

Rezon, pronounced REE-ZON, is an alternative spelling of reason. Protecting the brain has reason and justification.

Our mission

When founder Judith McMinn first established Rezon, it was because she had identified something missing from sports. While traditional protective headwear focused on the head and skull, there was nothing effectively protecting the brain.

With more and more cases of neurodegenerative disease in sports coming to light, Judith worked alongside leading global experts to develop brain protection.

Rezon’s mission is to offer every athlete the option to protect their brain and performance.

  • We want to challenge sports, clubs, schools, players, parents and coaches to take the science around brain health more seriously.

  • We want to ensure that athletes young and old no longer have to face the potential outcome of neurodegenerative diseases like CTE.

In fact, right now, there is more regulation around protection for teeth and shins, than there is for the brain in sport. We don’t think that’s good enough, so we’re here to challenge the status quo.

While sport thinks of the performance below the neck, we don’t – because the brain determines performance in sport and life.

Rezon keeps you in the game. For life.

  • Halos® is the only CE Category II PPE-certified protective headband globally. This is above any sporting governing body rules.
  • Reduces concussion risk by 74%, and reduces rotational forces by up to 61%* in concussive and sub-concussive impacts.
  • Halos® is rated five stars by US testing body Virginia Tech®.
  • After c. 1,500 sub-concussive impacts, Halos® still receives full marks against CE Certification criteria. Halos® lasts and protects.
