MET TRENTA MIPS HELMETPerformance Meets Safety MET's Trenta MIPS helmet is the epitome of a top-of-the-line cycling helmet. It strikes the perfect balance of safety, cooling, and aerodynamics. NACA vents strategically placed across the helmet provide optimized airflow without affecting the aerodynamics of the helmet. Rear deflectors in the form of two large exhausts allow for the exit of warm air. Coupled with the NACA vents and exhaust ports is the tube-shaped tail which works in synergy with both front and rear ports to save as many watts as possible without affecting airflow and ventilation. As for safety, MET has specced the Trenta out with class-leading brain protection from MIPS which helps to reduce impact forces directed towards your head in the event of a crash. In addition to MIPS, MET has utilized EPS foam to provide the maximum level of protection without adding unnecessary weight to the helmet. The SAFE-T ORBITAL fit system ensures that the helmet always fits perfectly and offers 360 degrees of adjustment. A dedicated sunglasses port lets you securely store your sunglasses when they're not in use.
