The MET Trenta 3K Carbon MIPS is a performance road bike helmet developed with elite athletes, winner of the TDF and the legendary classic Liège Bastogne-Lüge as well as the Lombardy tour. Designed to keep the head cool even during the toughest effort and save energy with every step into the pedal. The MET Trenta 3K Carbon MIPS is the most advanced road bike helmet MET have ever developed - now with MIPS Air, the lightest and most advanced safety system to reduce rotational energy. MIPS Air Safety SystemMET makes no compromises in terms of safety. With MIPS Air, MET have integrated the lightest and most advanced safety system to reduce rotational energy into the padding. MIPS Air has been specifically designed and engineered to reduce rotations that otherwise transmit to the head in certain falls. MIPS Air is integrated into the padding of the Trenta 3K Carbon MIPS and allows 10-15 mm relative metering between the energy-absorbing EPS shell and the padding.
