Leatt's Fusion 3.0 is the All-In-One Protection Solution

A difficult part about outfitting yourself with protective gear is making sure all your pieces are compatible and work well together - like your bicycle neck brace and upper body armor. The innovators at Leatt have come up with a great solution.

The Leatt Fusion 3.0 is a unique option that combines neck, chest, back, flank and shoulder protection in one piece of body armor. CE tested and certified for both personal protective equipment and impact protection; the Fusion offers a level of safety that other options don't. We think it is the best option for riders who want to combine all their upper body protection gear without spending an arm or a leg. 

The 3D design is easy to adjust and offers a surprisingly comfortable fit. Made of both hard shell material and 3DF AirFit soft ventilated impact foam, it fits around your body for a snug yet protective feel while riding. The pivot points in the front and back allow for ease of movement during use, so you never feel like you're too rigid wearing it. 

The Fusion takes the incredible neck brace design that Leatt is known for and adds all the complimentary protection you could want for your upper body. At a price that is comparable to most neck braces, it might be the best value if you are looking to maximize your level of protection.

About Leatt

Sometimes it takes a tragedy to create 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 meets varying needs of downhill mountain bikers, BMX bikers, and skiers and snowboarders.
