Rezon Halos®: Protecting Your Brain in Martial Arts
Halos® is a groundbreaking martial arts headguard that protects the brain in Taekwondo, Karate, Kickboxing, Muay Thai and sparring. It’s the only headgear of its kind that is designed to reduce your risk of concussion and developing Chronic Traumatic Encephalopathy (CTE) from the accumulated damage of sub-concussions.
Why Halos®?
- Reduces concussion risk by 74%*
- Reduces rotational force to the brain by up to 61%, and linear force by up to 64%*
- Internationally recognised Virginia Tech 5 star safety rating
- CE/UKCA Category II PPE-certified
- Sleek, lightweight, flexible and hypoallergenic
- Water and tear-resistant
- Machine washable
*based on independent testing

Why Head Protection Matters During Martial Arts Sparring
Repeated head impacts during sparring are a significant risk to long-term brain health in striking martial arts. In Taekwondo, Karate, Kickboxing, Muay Thai and other striking disciplines, sparring exposes participants to repeated punches and/or kicks to the head. Most head impacts will not cause a concussion, but they still transmit damaging forces to the brain.
These smaller-force impacts are known as sub-concussions. Unlike a concussion, a sub-concussion produces no symptoms, meaning a fighter can continue training without knowing that the brain has experienced an injury. The effects of repeated head impacts accumulate over time.
During a strike to the head, both linear and rotational forces are produced. Rotational forces cause the brain to move and rotate inside the skull. This is associated with tearing of tiny blood vessels and brain cells resulting, over time, in the breakdown of the blood-brain barrier and the creation of damaging neuro-inflammation.
This is why brain injury in martial arts is not simply about avoiding a knockout or diagnosed concussion. The cumulative exposure to repeated sub-concussive impacts during years of training and sparring is an important brain injury risk.
The best mitigation is to reduce the transmission of rotational and linear forces to the brain.
Rezon Halos® is designed specifically for this purpose. Patented Rotection® technology has been independently tested to reduce rotational force transmission by up to 61% and linear force transmission by up to 64%.
Rezon Halos® Martial Arts Head Guard
Every head impact creates rotational forces to the brain.
This is associated with the tearing of tiny blood vessels and brain cells; and over time, in the breakdown of the protective blood-brain barrier and the creation of damaging neuro-inflammation. This increases the risk of longer-term neurodegenerative consequences, including Chronic Traumatic Encephalopathy (CTE).
CTE is an early onset-dementia that typically occurs in ages 30-50 but can occur in teenagers and is a condition almost unique to contact and collision sports players.

The Brain is Vulnerable
In sports, the brain is vulnerable to rotational forces from both concussions and sub-concussions.
Sub-concussions are small force impacts that damage brain cell function, but do not produce evident signs or symptoms of concussion – so they go unnoticed. Sub-concussions are over 500 times more common than concussions in sport.
Repeated sub-concussions impact memory and attention, suppress brain function, and contribute to later life mood and behaviour problems including CTE. The risk and severity of CTE is caused primarily by the cumulative damage of multiple sub-concussive impacts, and not by concussions.
How does Halos® protect the brain?
Halos® protects your brain from rotational forces – this is where your brain rotates within your skull on impact, and is a lot more common than you think.
And that’s the biggest issue in brain injury: the undetected damage of rotational forces from repeated sub-concussions goes unnoticed, yet they’re progressively tearing brain cells and blood vessels, damaging the protective blood-brain barrier, and causing brain inflammation.
Halos® has nine protective layers, wrapped around the most critical areas of your head. On impact, each of these layers move over each other, reducing the transmission of rotational forces to the brain. Also three specific layers deform, further reducing impact energy.
Without wearing a Halos® in sport, your brain is subjected to damaging rotation. Halos® has been proven to reduce rotational forces by up to 61%. That’s a significant reduction for every player at every level, with the intention of reducing the risk of neurodegenerative consequences, which only start to be seen when the damage to the brain is already done.
Award-Winning Brain Protection for All
Rezon Halos® is suitable for use by all ages, players and sports in schools, universities, clubs and leagues.
Halos® gives every athlete the option to protect their brain, with a medically endorsed and legal protection product.
