Leatt 3DF 5.0 Knee Guard for Juniors gives Low-Profile Protection

When your child is riding the mountain or racing BMX, they should be protected. The Leatt 3DF 5.0 Knee Guard for Juniors gives their legs the protection you have come to expect from Leatt, without the excess size or bulk. What stands out for us when it comes to the 3DF 5.0 for Juniors is how easily it fits under pants and can be worn as a no show option.

Sometimes soft shell pads get a bad wrap. They aren't hard shell so their protection isn't of the same quality, but that isn't the case with the Leatt 3DF 5.0 for Juniors. These soft CE certified 3DF knee guards scored a total of 13 points in the Leatt protection rating system. It helps to show that you don't need a hard shell that's excessively bulky to achieve a solid level of protection. 

The 3DF impact foam is innovative in that it is soft but instantly becomes energy-absorbing upon impact. When put under extreme force or impact, the padding will harden to help minimize the blow. 3DF soft foam is just another game-changing innovation by Leatt. 

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.
