Customer reviews

Rezon Halos® is worn across 19 sports and 35 countries.

“I bought Halos® for my two sons who play football and rugby. I was looking for protection for their developing brains as awareness grows around the long-term effects of repeated head impacts.

They find them comfortable, they stay in place, and they are proud to wear them. Knowing I’m helping to reduce the impact on their brains gives me huge reassurance.”

“I wore Halos® throughout the Dubai 7s in 32°C heat and didn’t notice it during the game. It felt totally comfortable and gave me confidence that my brain had some additional protection during heavy contact.”

Rotection® Technology

Engineered to reduce rotational forces, which are the primary mechanism of brain injury.

Rotection® is a proprietary, nine-layered, comfortable, lightweight protective system to protect the brain across contact, collision, and combat sports. Independently tested at Virginia Tech, Halos® with Rotection® technology demonstrated up to a 61% reduction in rotational forces*. Deliberately designed to protect your brain.

Why Halos® is different.

Rezon Halos® is the only non-helmeted head worn protection to hold both CE / UKCA Category II PPE certification and a Virginia Tech 5 Star safety rating.

Conventional headgear in sport is designed to only protect from surface injury, cuts and abrasions. Halos® is different, it is brain protection.

Halos® is engineered to protect your brain by reducing the transmission of rotational forces in sub-concussive and concussive impacts. By lowering exposure to these forces, Halos® is focused on reducing neuro-inflammation and lessening the risk of triggering longer-term neuro-degenerative consequences, including CTE, motor neurone disease, and Parkinson’s disease.

Why do you protect your shins and teeth, but not your brain?

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.

Is flag football safe?

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.

Frequently Asked Questions

Yes. Youth research found substantially lower head-impact exposure in flag football than tackle football. In one study, tackle players experienced a median of 378 head impacts over a season compared with 8 for flag football players [1].

Flag football is safer than tackle football, but that does not mean that there is no risk of brain injury from head impacts.

Yes. Concussion can occur through accidental player collisions, falls, head-to-head contact and head-to-ground impacts. A 2025 US injury study found player-to-player collision was the most common mechanism of flag-football injury [6]

Flag football substantially reduces head-impact exposure compared with tackle football and is a safer option [1]. However, children can still experience collisions, concussions and sub-concussive impacts, so reducing avoidable brain-force transmission remains important. Wearing Rezon Halos® further reduces concussion and brain injury risk by reducing the transmission of rotational forces when head impacts do occur.

“Non-contact” describes the removal of deliberate tackling; it does not mean players can never make contact. Players run at speed in close proximity, compete for passes, change direction and fall, meaning accidental collisions and head impacts still occur.

The protective value of headgear depends on what it is designed and tested to do. Brain protection should be evaluated by its ability to reduce the linear and rotational forces associated with concussion risk, using independent biomechanical testing such as the Virginia Tech STAR methodology [11]. A flag football head guard designed to reduce the transmission of rotational forces is the best mitigation to reduce concussion and brain injury risk.

The most relevant head protection for brain injury risk is equipment independently tested to reduce rotational as well as linear force transmission. For a full comparison of available approaches, read What Is the Best Head Protection for Flag Football?.
