Helmet Size Guide
How to Measure
Use a soft measuring tape and wrap it around the widest part of your head — typically about 1 inch (2.5 cm) above your eyebrows and ears. Keep the tape level around the back of your head. If you're between sizes, we recommend sizing down or choosing a helmet with an adjustment system. However, for all KASK helmets, we recommend sizing up by 2cm.

Product Information
Designed for riders who demand advanced protection without excess weight, Revi's The Challenger Helmet combines cutting-edge safety engineering with premium comfort and functionality. Built with a hybrid dual-shell construction, Revi utilizes a durable ABS outer shell paired with lightweight polycarbonate (PC) to deliver exceptional impact resistance while maintaining balanced weight distribution.
At the core of the helmet is a multi-density, zoned EPS liner integrated with the ESA® Shock Absorption System. This advanced system is engineered and rigorously tested to reduce both linear and rotational impact forces, enhancing protection during high-energy impacts.
Certified to ASTM F2040 safety standards, the Challenger helmet meets trusted industry benchmarks for reliable, all-day protection. An optimized ventilation system promotes consistent airflow to regulate temperature and reduce moisture buildup in varying conditions.
Comfort and usability are elevated through a precision dial-adjust fit system, ensuring a secure and customized fit. The Fidlock® magnetic buckle allows for fast, one-handed operation, even with gloves, while removable, washable liners and ear pads make maintenance effortless. Audio-ready ear pads accommodate drop-in speaker systems, and integrated goggle retention keeps eyewear securely in place during aggressive riding.
Lightweight, protective, and purpose-built, the Challenger delivers premium performance for riders who prioritize safety, comfort, and clean design.
