Alpinestars SX-1 Plasma Knee Guards

Features:

• Plasma Knee Protector embedded into a highly ventilated semi-rigid frame construction for superior impact protection
• Integrated Dual Gear System (DGS) promotes the natural articulation of the knee
• Dual density co-injected frame for a supportive structure with unrivaled comfort and adaptability — engineered with a scooped lower extension made from a soft polymeric blend to avoid any pressure points associated with a hard edge from occurring as a result of the boot pushing against the protector
• The same scooped design is also applied to the upper extension, preventing the protector from digging into the skin and causing discomfort while riding
• Controlled natural movement — Dual Gear System (DGS), with integrated gear profiles in both the upper and lower frames that ensure a smooth hinge function to promote natural articulation of the knee
• Strategically positioned over-injected rigid and flexible shells to ensure the frames adapt to a wide variety of leg circumferences
• Lightweight knee protection with extensive protective coverage
• Upper and lower frames are constructed from a high performance polymer for optimized levels of flexibility and strength as well as excellent weight saving properties
• High levels of ventilation
• Slim ergonomic design
• Dual strap closure system features hook and loop with snap-fit buckles for easy in and out and a personalized, secure fit
• Sold as a pair

Protection:

• Knee protector: EN 1621-1:2012 LEVEL 1
• Constructed from a USDA Biobased viscoelastic material, which is molded into a structure that is pliable in all directions while maintaining the ability to dissipate impact energy
• The Patella System is engineered to offer full coverage of the knee cup regardless of the degree of extension, while the rigid outer Patella System shell prevents injuries from handlebar strikes
• The upper and lower frame's integrated dual pivot hinge system follows the natural movement of the knee and keeps the protector well positioned while riding
