The Alpinestars SX-1 Plasma Knee Guards are engineered to provide superior impact protection combined with maximum comfort for riders demanding high performance gear. Featuring a plasma knee protector embedded into a highly ventilated semi-rigid frame construction, these guards excel in dissipating impact energy while maintaining a lightweight profile. The design incorporates a dual density co-injected frame that offers a supportive yet adaptable structure, with a scooped lower extension made from a soft polymeric blend to eliminate pressure points that can occur with hard edges. This thoughtful design extends to the upper extension as well, preventing discomfort caused by the protector digging into the skin during extended rides.
The dual gear system (DGS) integrated into both upper and lower frames ensures natural knee articulation, facilitating controlled movement without sacrificing protection. Strategically positioned over-injected rigid and flexible shells allow the frames to adapt to various leg sizes, ensuring a secure fit for many riders. The Patella System provides full coverage of the knee cup, regardless of the degree of extension, with a rigid outer shell that guards against handlebar strikes.
Constructed from high-performance polymers, the lightweight design offers excellent flexibility and strength, making these guards suitable for demanding riding conditions. The perforated design enhances ventilation, keeping knees cool during intense activity. The slim ergonomic profile, combined with a dual strap closure system featuring hook-and-loop fasteners and snap-fit buckles, ensures a personalized and secure fit that’s easy to put on and take off. These knee guards are an ideal choice for riders seeking durable, comfortable, and highly protective gear for their adventures.
