These guards incorporate the removable Nucleon Plasma knee protector, which boasts a biobased viscoelastic material certified by the USDA.

With a keen focus on flexibility, the protectors bend with the rider’s movements, offering a personalized and secure fit. Ventilation is also a cornerstone of the design, featuring a 3D mesh front panel that fosters exceptional breathability. The knee zone is safeguarded by abrasion-resistant fabric, while the lower leg’s back utilizes soft, stretchy mesh that adapts comfortably to varied calf sizes. Furthermore, the construction behind the knee counteracts heat accumulation and augments air circulation, underlining the guards’ proficiency in delivering comprehensive and adaptive knee protection for the youth rider.
