Ergonomic design and engineered shape for ideal fitment with Alpinestars A-5 S
Left and right rigid frames are made from a polymer compound combination with the internal smooth edge made of soft-injected EVA to provide a great fit and stable positioning
Overall frame construction dissipates energy loads by transmitting them across the back
Flexible back connector between the left and right frames allows the neck support to follow the body's movements when riding
Chin plates on the front dissipate pressure of the helmet when impacting
Quick-release closure system to easily engage or disengage the neck support
Compatible with Alpinestars A-5 S; can also be worn on its own using the A-strap (included in the YNS kit)
