As pioneers of removable chin bar technology, we have a legacy to uphold and overcome. We designed the Super Air R from the ground up to push the boundaries of performance and versatility. With class-leading Flex Spherical MIPS technology, superior ventilation, a total weight that is 22% or 144 grams lighter than its predecessor and an easy 2-click removable chin bar, this is a true all-mountain performer.Specifications: Total Vents:- 18 Helmet Vents, 8 Chin Bar Vents, 4 Brow PortsVentilation:- Overbrow Ventilation Features Intake Ports On The Brow Of The Helmet To Usher In Cool Air And Push It Through The Air-Channel Matrix For Full-Head VentilationCompliance:- Cpsc BicycleMips:- Flex Spherical + Mips - Comprehensive Energy Management - Flex Spherical Enhances Our Ability To Address High-Speed Impacts, Low-Speed Impacts, As Well As Rotational Impacts.
