Alpinestars quality: The SX1 Knee Guard has been designed in line with Alpinestars' A range of protectors. Ideal for off-road riders who want the thinnest, most lightweight and super-ventilated impact protection. Featuring an asymmetrical and slim-profile design, the SX 1 offers a safe, personalised and tight fit while at the same time promoting excellent levels of movement.

The protection you need for off-road: CE certified at Level 1, this knee guard features an energy absorbing floating protection cup for continuous coverage regardless of the leg position. What makes the SX1 really special is the dual pivot hinge system. It allows the guard to follow the natural movement of the knee keeping it well positioned at all times and helps to avoid hyper-flexion.

The comfort you want: The protector plates are strategically perforated and the patella cup is backed by soft padding ventilation and an adaptive fit. The thick airprene dual straps are located above and below the knee, avoiding the knee bend. It's important to note that the SX 1 combines easily with any of the Alpinestars Tech boots!

Note: For sizes small or medium, choose size M in the drop-down. For a large or XL choose XL in the drop-down.
