The Tyrant MIPS helmet was developed to meet the needs of the new generation of trail and dirt jump riders. The Tyrant heralds the advent of mountain biking. While the style is subtle, the Tyrant has countless technical breakthroughs, including Wind Tunnel Ventilation and MIPS Spherical Technology. The outer shell of the helmet is made of EPS, which absorbs impact energy very well in high-speed crashes, while the inner shell is EPP foam with lower density to absorb residual energy. The additional coverage of this "full cut" design extends the protection zone and provides even more safety without sacrificing comfort.
In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
Wind Tunnel ™
Wind Tunnel ™ Ventilation is Giro's proprietary system of internal channels and active vents that channel cool, fresh air over and around your head, squeezing out the exhausting heat and stale air. A difference that you can see and feel - on every ride.
Multi-Directional Impact Protection System (MIPS) MIPS is a helical level system within the helmet designed to slow down or prevent the amount of energy being transmitted to the head or away from the head.
