THIS AEROHEAD MIPS HELMET TAKES THE SAME WIND-CHEATING SILHOUETTE AS THE LEADING-EDGE AEROHEAD ULTIMATE BUT ADDS INCREASED VENTILATION TO KEEP TRIATHLETES AND TIME TRIALISTS COOL WHEN THE COMPETITION IS HOT. By using a polycarbonate shell, Wind Tunnel ventilation and internal channeling, this helmet is proven to boost cooling power while remaining aerodynamic. Additionally, Aerohead MIPS features a wrap-around eye shield that offers an impressive field of view with the convenience of a magnetic anchor attachment to allow easy storage of the lens in the "flipped up" position - perfect for fast swim-to-bike transitions.
