Nucleon Plasma - Full Back Protector Insert for Motorcyclists (Red/Black)
Built for riders who take safety seriously, the Alpinestars Nucleon PLASMA Back Protector combines cutting-edge protection with all-day comfort. Whether youâre hitting the track, touring long distances, or commuting daily, this CE Level 2 certified back protector is designed to keep your spine protected without restricting movement.
At its core is Alpinestars USDA-certified bio-based Nucleon PLASMA material, a smart viscoelastic compound that stays soft and flexible during normal use but instantly firms up on impact to absorb and disperse energy. For added security, a central semi-rigid thermoplastic panel reinforces the most critical spinal zone. The ultra-breathable âMâ shaped design promotes excellent airflow, while the moisture-wicking tactile liner helps keep you cool and dry on long rides or in hot weather.
