Alpinestars SX-1 Knee Guards

Serious knee armor for the serious motocrosser. Where conventional knee/shin guards protect mainly from roost and slides onto the knee, the Alpinestars SX-1 Knee Guards actually brace the knee joint against injuries that can be caused by an especially hard or awkward landing. Using a Dual Gear System with integrated hinge gears, the Alpinestars SX-1 Knee Guards offer protection against hyperflexion without limiting mobility. The shin and thigh plates are perforated for breathability, while the polyurethane patella cup uses a floating design to maintain coverage and viscoelastic padding for comfort.

Features:

  • CE certified knee brace EN 1621-1:2012 K type A (level 1)
  • Upper and lower frames are constructed from a high performance polymeric material blend for optimized levels of flexibility and strength as well as excellent weight saving properties
  • Polymer protector plates are strategically perforated for maximum breathability and air ventilation
  • Dual Gear System (DGS), a dual pivot with integrated hinge gear system for dynamic fit for mobility
  • Upper frame features extended frame for increased thigh protection without compromising mobility
  • Patella construction features floating protection cup for continuous coverage and mobility regardless of leg position
  • Patella cup constructed from impact resistant PU foam knee cup CE certified Type A
  • Patella cup backed by soft, viscoelastic padding for adaptive fit and breathable air mesh for ventilation and comfort
  • High abrasion-resistant fabric with an over injected TPU frame structure on outer central knee-cup area to improve the impact performances
  • Thermoformed foam backing for excellent comfort against the skin
  • Frames are asymmetrical and feature a slim, ergonomic design for comfort and performance fit
  • VELCRO® brand and TPR dual strap closure systems for easy in and out and a personalized, safe fit
  • Straps feature Airprene for optimized comfort and airflow
