The Science That Changes Everything
How KATO Works
Advanced Restriction Technology
KATO Collar uses scientifically-engineered restriction technology to limit excessive head and neck movement during impact. By controlling the range of motion at critical moments, KATO reduces the force transmitted to the brain, providing protection when helmets alone cannot.
This innovative approach addresses the root cause of brain injury: rapid acceleration and deceleration of brain inside the skull during the critical post-impact window.
✓ What KATO Does
- Reduces head and neck acceleration during direct and indirect impact by limiting head and neck range of motion
- Provides continuous protection during the critical 485ms post-impact window
- Works seamlessly with all helmet types
- Maintains full athletic performance
✓ What KATO Doesn't Do
- Does not restrict blood flow or breathing
- Does not impair range of motion during normal play
- Does not affect athletic performance metrics
- Does not require special maintenance or fitting
- Does not cause discomfort during extended wear

PROTECT YOUR BRAIN WHEN HELMETS CAN'T
KATO provides continuous protection throughout the entire injury event
Clinical Evidence & Research
Years of development and rigorous testing with real athletes, proven results
Proven Impact Reduction
Without KATO
Brain tissue experiences full force of impact, leading to stretching and tearing of neural connections during the critical post-impact window.
With KATO
Restriction technology limits excessive motion, significantly reducing force transmitted to brain tissue throughout the entire 485ms impact event.

Why Helmets Aren't Enough
Helmets protect the skull. KATO COLLAR protects the brain.
The Limitation of Helmets
Traditional helmets are engineered to prevent skull fractures and reduce the initial impact force. They excel at protecting the outer structure of your head.
But here's what they can't do: stop your brain from moving inside your skull.
No matter how advanced the helmet technology, they cannot control the secondary motion of brain tissue that occurs in the 485ms after impact — where brain injuries can still occurr.
Protect Your Future
Even small hits add up. Repetitive sub-concussive impacts can cause lasting brain damage that affects your life long after you leave the field.
Cognitive Decline
Repeated impacts can lead to decreased mental sharpness, memory problems, and difficulty with concentration and decision-making as you age.
CTE Risk
Chronic Traumatic Encephalopathy (CTE) is a progressive brain disease found in athletes with a history of repetitive brain trauma, even without diagnosed concussions.
Neurological Conditions
Studies show increased risk of early-onset dementia, Alzheimer's disease, and other neurodegenerative conditions in athletes with repeated head impacts.
