Alpinestars SX-1 Plasma Knee Guards Black/Red/Cool Gray 6500326-1498

The Alpinestars SX-1 Plasma Knee Guards deliver advanced impact protection with a lightweight, highly ventilated design engineered for the most demanding riding conditions. Featuring a plasma knee protector embedded into a semi-rigid frame, these guards provide superior shock absorption while maintaining the flexibility needed for natural movement on the trail or track.

The construction utilizes USDA Biobased viscoelastic material, molded into a pliable yet energy-dissipating structure that offers excellent shock absorption in all directions. This innovative material ensures long-lasting durability without sacrificing comfort. The dual density co-injected frame provides a supportive yet adaptable fit, incorporating scooped lower and upper extensions made from a soft polymeric blend to eliminate pressure points and discomfort caused by hard edges.

To promote proper knee articulation, the integrated Dual Gear System (DGS) facilitates controlled, natural movement. Strategically positioned over-injected rigid and flexible shells allow the guards to conform to a wide range of leg profiles, ensuring a personalized and secure fit. Protection is further enhanced by the Patella System, which fully covers the knee cup regardless of the extension angle, while a rigid outer shell guards against impacts from handlebars and other hazards.

High-performance polymer frames combine strength and flexibility while remaining lightweight to reduce rider fatigue. The slim ergonomic profile is complemented by a perforated design that enhances airflow, preventing overheating during prolonged sessions. For ease of use, the guards feature a dual strap closure system with hook-and-loop and snap-fit buckles, allowing for quick, stable, and secure adjustments throughout your ride.
