Leatt 3DF Hybrid Knee Guard offers Heavy Duty Protection

Knee protection is extremely important when riding BMX or downhill MTB. Leatt had this in mind when crafting the 3DF Hybrid Knee Guard. They took two of their best impact technologies and blended them into a heavy duty pad that will do all it can to protect your knees while you ride. 

We understand that just the idea of soft shell padding can make some riders uneasy. With the Leatt 3DF Hybrid Knee Guard, you can have both protection materials in one hybrid pad. The 3DF Hybrid scored a 17 on Leatt's total impact protection test, which makes it one of the highest rated knee protection pads they offer. 

While the hard shell adds great protection, don't forget that 3DF soft shell protection is incredible as well. 3DF impact foam is innovative in that it is soft but instantly becomes energy-absorbing upon impact. When put under extreme stress or impact, the padding will harden to help minimize the blow. 3DF soft foam is just another game-changing innovation by Leatt. 

Despite its heavy duty profile, The Leatt 3DF Hybrid Knee Guard has significant ventilation throughout with Anti-odor MoistureCool and AirMesh wicking fabrics. They help to keep the bad smell out while letting air flow freely. The hard shell pad is also ventilated to maximize airflow during use. 

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.
