The Defender Air riding hats are certified to PAS015 (2011) with Kitemark, VG1.040 2014.12 and ASTM F 1163.15 standards. The hat is the most adjustable around perfect for all shape heads and has a revolutionary air pump system which provides ultimate comfort and a bespoke fit. The 3 hidden air pockets in the liner are inflated by pressing its concealed air pump until you get the fit you want. The quick dry liner is moisture wicking and anti-microbial this is helped by the multiple air vents. The Defender features a matte Polycarbonate and Advanced ABS Composite outer shell; injection moulded shell design. With enough features to appeal to those seeking everything a helmet could possibly offer, wrapped in a package that traditionalists can appreciate, One K™ has the best of both worlds. All OneK Defender hats comes with slots compatible with the magnetically-attached click in sun visor perfect on sunny days to protect your eyes from UV rays and dust particles when protection is needed most.
