Concepto de diseño & desarrollo
""
The Alpinestars SM5 delivers competition-grade off-road impact absorption with maximum cooling throughput, pairing extreme cooling throughput with competition-grade roost protection. Built around a High-Yield Impact-Resistant Polycarbonate / Lexan shell weighing 1411g, its multi-density EPS matrix is aerodynamically sculpted to isolate cabin noise to ~100 dB while dissipating kinetic impact forces across DOT, ECE 22.05 benchmarks. An ultra-breathable, antimicrobial interior liner stabilizes the helmet during aggressive terrain vibration, locked in securely with track-proven Double D-Ring retention.
