Alpinestars Youth Bionic Plasma Knee Protector – Black/Red

An off-road knee protector built for young motocross and trail riders. The core is a removable Nucleon PLASMA insert made from USDA-certified biobased viscoelastic material that absorbs and disperses impact energy while keeping coverage across every riding position – CE Level 1 certified to EN 1621-1:2012.

A ventilated 3D-mesh chassis with an abrasion-resistant front panel and open-back construction keeps air moving in the heat. Multi-directional pliability lets the protector follow the natural movement of the knee, while silicone upper hems and stretch rear mesh hold it securely in place. Extra side padding extends the protected area, and the insert pulls out for easy cleaning.
