Back protector Alpinestars Nucleon Plasma Strap
The Alpinestars Nucleon Plasma Strap is an advanced back protector engineered to provide maximum impact absorption, flexibility, and ventilation for road and track riders. Built with USDA-certified bio-based Nucleon Plasma viscoelastic material, this motorcycle back armor features a semi-rigid thermoplastic central spine zone that effectively disperses energy across critical areas. The engineered M-pattern layout delivers exceptional airflow and continuous heat dissipation, while the tactile soft-touch backing ensures high structural integrity and rider comfort. The ergonomic harness system with V-configuration lateral straps guarantees a performance fit that follows the spine's natural curvature. For optimal comfort on the bike, pair this standalone back protector seamlessly underneath your motorcycle jacket or racing leather suit.
