Alpinestars Supertech M10/M8 Crown Pad - Replacement crown pad for Alpinestars Supertech M10 and Supertech M8 Helmets. A low friction 'slip' layer is incorporated into the Supertech helmet, between the comfort padding layer and the multi-density polymer energy absorption shell. When energy is impacted upon the helmet, causing a rotation force, the MIPS layer allows for movement of the inner absorbtion layer to damp and re-direct the energy before causing significant acceleration stress to the brain. This mitigates the causes of brain injuries, such as concussion. With an adjustable pad that is connected to the helmet inner shell, it is possible to raise or lower the helmet fit and also, to tilt the helmet forward, or backwards.Replacement crown padFits Helmet Alpinestars Supertech M10 and Supertech M8 HelmetsAdjustable pad that is connected to the helmet inner shellHigh QualityImported.
