The MET Trenta 3K Carbon MIPS Road Helmet is a high-performance road helmet designed with elite cyclists and worn to victory at Le Tour de France and the monuments of Lige-Bastogne-Lige and Il Lombardia. Engineered to keep your head fresh and save you energy with every pedal stroke, the MET Trenta 3K Carbon MIPS Road Helmet is the most advanced road cycling helmet MET have ever made, now upgraded with the addition of Mips AIR, the lightest and most advanced rotational management system in existence.

Features

  • MIPS AIR Brain Protection System is cleverly integrated into the padding making it the lightest and most advanced rotational management system available.
  • 3K Carbon Technology: MET's R&D team have taken advantage of carbon fibres elastic modulus which allows them to reduce the density of the EPS foam by 20%, without affecting the capacity of the helmet to absorb energy. The result is a lightweight yet better-performing shell that sets a new standard for ventilated helmet design.
  • NACA Vent: Originally developed by NACA, precursor to NASA, the position of an inlet at the front of the helmet harnesses the power of the Venturi effect, pushing out warm air within the helmet through specially positioned exhaust ports. This ensures constant airflow through the helmet, without creating drag.
  • Rear Deflectors: The back of a helmet has a huge impact on how well-ventilated it is, with the exit of warm air from within a key priority. The MET Trenta 3K Carbon Mips features a flat rear deflector inclined at 25, which makes it possible to include two wide exhausts that optimise airflow when you're on the drops and riding hard.
  • In-mould polycarbonate shell with EPS liner
  • MET Safe-T Orbital Fit System
  • 360 Head belt, vertical and occipital adjustments leave you with an individual fit
  • Air Lite straps with adjustable divider to maximise aerodynamic and comfort
  • 19 Vents, engineered internal air channeling system to improve ventilation and comfort
  • Sunglasses ports to securely dock sunglasses when climbing or resting
  • Tube-shaped Kamm virtual foil tail to improve aerodynamics
  • Limited head contact surface (30% contact area) to maximise ventilation
  • Reflective rear decals to enhance visibility in low-light conditions
  • Helmet soft bag included
