New and improved for 2025, SmartFlex® technology offers the same body-mapped, flexible protection, now in a sleek, pre-curved shape to provide an ergonomic and secure fit. As a non-Newtonian material, SmartFlex hardens on impact, absorbing the energy, then returns to its original state.
The pre-curved design allows for expanded coverage while appearing slimmer, delivering more confidence and less distraction to Go Next Level.
Increased Airflow
Stay cooler while riding thanks to the new internal channels. X4 pads are also machine washable, so not only do the pads reduce heat and sweat build up, but they're also easy to clean.
