Leatt AirFlex Pro Knee Guard Offers Bulk Free Protection

No rider wants to sacrifice comfort or range of motion for protection. With the Leatt AirFlex Elbow Guards, you will have comfortable, non-bulky knee pads with the slimmest profile available. 

Made with a new technology called ArmourGel, the impact protection offered by the AirFlex is unlike any other Leatt pad on the market. It is the most flexible and easy to wear pad we offer.  It can fit under most long pants with ease, and because of its sleeve design and silicone laminates, it will stay in place all day. 

Some might be skeptical about the pad's ability to protect, but its total Leatt protection score of 15 points is very comparable to other Leatt knee pads featuring both hard shell and soft shell technology. 

The Leatt AirFlex Pro Knee Guard also offers excellent ventilation with Anti-odor MoistureCool and AirMesh wicking fabrics. They help to keep bad smell out while letting air in.

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 meet varying needs of downhill mountain bikers, BMX bikers, and skiers and snowboarders.
