Alpinestars BNS TECH-2 Technical Cross Enduro Motorcycle Collar Black Gray

The Bionic Neck Support Tech 2 is made from an advanced, high performance carbon polymer compound, and is designed to help prevent injury by dissipating and diverting impact forces away from the neck and spine. The BNS works when the rider's helmet contacts his frame at the moment of impact, providing a clean, solid surface that instantly channels the compressive energy of impact away from the neck onto the BNS. Featuring Alpinestars exclusive, revolutionary PFR rear stabilizer for progressive force cushioning, the BNS Tech 2 is designed for cross and off-road use, offering a stable and customized fit, incorporating new and innovative solutions such as the new quick release.

• Incredible lightness and driving comfort.
• Low weight without compromising strength and stiffness.
• Resistance to temperatures below 0°C.

• The very light Strap System can be worn over or under the jersey.
• Integrates a bio-organic design for superb ergonomics:
• The rear stabilizer promotes progressive force dispersion (PFR) by dissipating energy loads through transmission to the back and shoulders away from the spine (thoracic vertebrae) and is pivotally connected to the frame.
• Frame construction with improved helmet contact during impact – rear support edge that fits closer to the body, increased width to accommodate different helmet sizes and raised chest to reduce hyperflexion.
• Innovative quick release for quick donning and doffing with a secure and comfortable closure.
• Compressed EVA foam compound padding to distribute impact forces over a larger area while maintaining lightness
