Finally, a One K™ for smaller riders. Now in Junior sizing, they offer the same protection, quality and comfort as the current One K™ range, but with smaller internal helmet diameter, a thicker padded liner, and a smaller chin strap which is 15mm shorter in length than the adult sizes.

The Defender Riding Helmet features matte Polycarbonate and Advanced ABS Composite outer shell; injection molded shell design; washable quick-dry, moisture wicking, anti-microbial liner; stainless steel mesh; comfort padded harness with synthetic suede lining, hook & loop adjustment, and Fastex buckle; two side, two front, one back, and two center stripe vents. One K™ Helmets boast the perfect synergy between advanced technology and aesthetically pleasing 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. Certified to ASTM standards.
