What is Alternative Load Path Technology?  

Simply put, Leatt's patented Load Path Technology, used on all Leatt neck braces, spares your neck and back from absorbing all the energy of a blow. Instead, the neck brace intercepts the impact from the scull by dispersing the force, thus sparing you from a more serious, potentially season-ending neck injury. Working in conjunction with a full face helmet, the neck brace guards against extreme backward-bending of the head (hyper-extension); extreme forward-bending of the head (hyperflexion); and over-bending of the head to either side (lateral hyperflexion). Additionally, the neck brace is protective when the chin bar takes the brunt of a face plant and pushes the neck backward (posterior hypertranslation). In certain scenarios the neck brace can prevent axial loading.

Leatt Brace: A leader in neck protection

Dr. Leatt likes to say the Leatt Brace is ‘a helmet for your neck.’ Certainly that is one way to describe it. But the Leatt-Brace is so much more. The critical function of the Leatt-Brace is to reduce the velocity of the head after it has been set in motion due to the impact from an unanticipated crash. In simpler terms, the Leatt-Brace is designed to bring your head to a controlled stop after a collision.The Leatt-Brace does this by redirecting the energy of an impact from your head and helmet, down through your Leatt-protected neck, and on toward other parts of your body, such as your chest. As a device, the Leatt-Brace acts as a collar, reducing your head’s ability to jerk fully in any direction during a wipe-out. This means your head cannot hyper-flex forward, it cannot hyper-extend backward, and it cannot laterally hyper-extend. This also means that your neck and spine cannot be compressed due to some significant impact to the top of your head. Not withstanding its protective qualities, the beauty of this device is that it does not hinder your range of motion or your peripheral vision in any way while you participate in your given sport. To the contrary, it is so comfortable that you won’t really know you’re wearing it.

Leatt Neck Brace:  Invention from tragedy

Sometimes it takes tragedy to make change. Such was the case in South Africa in 2001 when Dr. Chris Leatt, a medical doctor and motorcycle rider, went to a racetrack with his son who himself had just begun to ride. There, Dr. Leatt witnessed the death of another rider, Alan Selby, from suspected neck injuries. Dr. Leatt was so shaken by the incident that he made it his mission to develop a device that would go a substantial way toward preventing this type of fatal injury in the future. After three years of research, development, and testing, Dr. Leatt introduced his first Leatt-Brace. However, it would be another two years before the Leatt-Brace would make it to market on a large scale. Today, Leatt-Brace is a worldwide leader in neck protection for extreme sports. Dr. Leatt likes to say the Leatt Brace is ‘a helmet for your neck’. Designers and engineers in the Leatt laboratory in South Africa have expanded their reach to high-technology protective armor that meet varying needs of downhill mountain bikers, bmx bikers, and skiers and snowboarders.
