Every watt counts. The Z20 Aero is built with that in mind, delivering uncompromising performance, innovation, fit, and comfort. With it's drag-defying shape, Progressive Layering, and Integrated MIPS, this helmet provides real world performance for riders who want to lead.

• Certifications: CPSC Bicycle, CE EN1078
• Vents: 10
• Overbrow Ventilation - Actively ushers cool air over the head and regulates temperature by drawing cool air into the intake ports and circulating it through a matrix of air channels.
• Progressive Layering - Bell utilizes two layers of foam; a hard EPS layer against the outer shell closer to the point of potential impact, and a less dense EPP layer closer to the head. Each layer has a thin hard shell molded into it. This allows their engineers to optimize fit in a more sophisticated manner and design helmets to manage a broader range of impacts with fewer compromises.
• Fusion In-Mold Polycarbonate Shell
• Float Fit Race Fit System (integrated with MIPS) - Custom fit at the highest performance, Seemlessly integrated with MIPS and offers three-way adjustability: height, pad width and tension.
• Aero-Optimized Shape
• No-Twist Tri Glides - Quick-adjust fasteners help keep straps flat and properly positioned.
• X-Static Padding - Quick-drying pad materials, woven with real silver fibers, inhibit growth of odor-causing bacteria and fungi.
• Sweat Guide - Sweat Guide pad design pulls moisture away from brow pad and away from eyewear.
• Lightweight Straps
• MIPS - MIPS stands for Multi-directional Impact Protection System, which is a leading slip-plane technology inside the helmet designed to reduce rotational forces that can result from certain impacts.
