Alpinestars SX1 Plasma Knee Protector - Black Red Cool Gray S-M

A hinged knee protector for off-road riding. A Nucleon Plasma pad sits inside a ventilated semi-rigid frame, the Dual Gear System lets the knee bend naturally, and a rigid Patella System shell covers the kneecap against handlebar strikes.

Key features

• Nucleon Plasma pad: USDA certified bio-based viscoelastic material that moulds to the knee and dissipates impact energy.
• Dual Gear System: Geared upper and lower frames give a smooth hinge for natural knee movement.
• Patella System: Covers the knee cap at any degree of bend, with a rigid outer shell against handlebar strikes.
• No hard edges: Soft polymeric scooped lower extension avoids pressure from the boot, and the scooped upper extension stops it digging in.
• Fits a range of legs: Rigid and flexible over-injected shell sections adapt to many leg sizes.
• Ventilated frame: Semi-rigid frame is highly ventilated and lightweight.
