The SM7 incorporates Alpinestars PLASMA technology into the lower side shell pads to help dissipate energy in the collarbone area and improve shock absorption. Its Visor Detaching System is engineered to release the visor when impact energy exceeds 15 joules, helping reduce weaknesses associated with conventional visor anchoring systems. A 25 mm nylon chin strap with stainless steel double-D rings provides secure retention, while removable strap covers simplify cleaning. Manufacturer and vendor part number: 8301627-2217-S.
