Road Bike Helmet – MET Trenta Mips, Black Matt Glossy
The MET Trenta Mips is a performance road bike helmet for anyone who rides frequently on Swiss roads and values efficient ventilation as well as high safety. At its heart is the MIPS C2 system, which can redirect rotational forces away from the head during certain crashes. This is complemented by an in-mould polycarbonate shell with EPS core, clearly structured internal air channels and the characteristic NACA ventilation opening at the front. In size M, the helmet weighs 250g; the sizes cover S (52–56 cm), M (56–58 cm) and L (58–61 cm), all CE-certified.
- MIPS C2 rotational protection, integrated between padding and EPS
- Weight approx. 250g (M), sizes S/M/L with 52–61 cm head circumference
- Safe-T Orbital fit system with 360° band, 4× vertical, 2× horizontal adjustment
- NACA ventilation opening and rear deflector for constant airflow
- Tubular rear section for aerodynamic flow management in drop bar position
- Eyewear ports, Air-Lite straps, reflective details, padded carry bag
- CE; AS/NZS certified, compatible with MET USB LED Light
Technical Details and Features
The MIPS C2 system sits between the comfort padding and EPS shell and allows defined relative movement during angled impacts to reduce the rotational forces acting on the head. The in-mould polycarbonate shell combines durability with low weight, while internal air channels guide fresh air from the front to the outlets. At the front, the NACA ventilation opening uses the Venturi effect to actively push warm air out of the helmet interior. At the rear, a 25° angled deflector supports two wide outlets, providing noticeably cooling airflow especially in racing position. The fit is ensured by Safe-T Orbital with 360° headband including vertical and occipital adjustment; the system is ponytail-compatible and can be combined with the MET USB LED Light. Practical sunglasses ports, Air-Lite straps and a padded, ventilated bag complete the equipment.
Applications and Benefits
Whether fast laps around Lake Zurich, long Alpine passes or brisk group rides: the Trenta Mips is designed for efficient cooling under load. The combination of NACA opening, tubular rear section and rear deflector keeps airflow stable without unnecessarily increasing drag. This makes it a good choice for hot summer days, intensive intervals and races in Switzerland. Thanks to eyewear ports, glasses stay securely stored when climbing, and the reflective details increase visibility at dusk. The CE certification ensures the legally required safety for road use.
Additionally, the Trenta Mips scores with a 5-star rating in the independent Virginia Tech helmet tests, which consider both linear and rotational impact energy. These tests provide objective guidance on which helmets most effectively reduce the risk of concussion. This makes the helmet ideal for riders who seek performance and want to approach safety in a data-driven way. We stock this model in Black Matt Glossy; depending on inventory, we carry two variants so you can quickly find the right size.
What the experts say
"The ventilation worked well, and the helmet didn't get overly sweaty, even on some epic rides in the heat."
Reviewer Ben Woodhouse rates the Met Trenta Mips 9/10, praising its excellent ventilation, comfortable padding, low-profile fit and light 260g weight. He sees it as a versatile helmet for group rides, climbs and hot weather, and recommends it at £229.99, noting it lacks an XL or wide-fit option.

"The advertised ventilation is excellent; you can really feel the air flowing over your head and keeping you cool.','context':'Ventilation'}],"
The Met Trenta 3k Carbon Mips is a top-end lightweight road helmet with strong ventilation, a very effective sunglasses port, plenty of fit adjustment and striking styling. The reviewer praises its light, airy feel and five-star safety rating, though the high price and minor issues with the Mips Air catching hair and occasional sunglasses gaps hold it back from perfection.
"The helmet has been designed and tested using the wind tunnel in the Newton laboratory of Milan, so it's good to see that Met hasn't relied purely on computers to validate the claims.'},{"
Jamie Williams finds the Met Trenta 3K Carbon Mips an excellent, light, cool and comfortable helmet that adds Mips rotational protection without a noticeable weight penalty. The main drawback is the high £280 price, which he considers justified only for those who want a single aero and ventilation helmet.
"airflow is brilliant, and it can be felt throughout the helmet as air moves from the front to the rear.','context':'Performance"
Aaron Borrill finds the Met Trenta 3K Carbon a clear improvement over its predecessor, with better ventilation, a tailorable Safe-T Orbital fit and strong safety credentials backed by Virginia Tech results. He considers it one of the best road bike helmets available, though its price of £350 is high.

Jan Gathmann testet den MET Trenta 3K Carbon Mips, der mit neuem Mips Air-Inlay, sehr geringem Gewicht von 221 g und einem präzisen Verstellsystem überzeugt. Der Autor lobt Passform, Verarbeitung und Tragekomfort, bemängelt aber, dass nicht alle Brillenmodelle gut passen, und hält den Preis von 320 Euro für High-End-Helme für im Rahmen des Üblichen.
Le MET Trenta 3K Carbon MIPS est jugé excellent, avec un confort appréciable, une très bonne ventilation et un look moderne. Le prix public de 320 € est élevé, même si le casque se trouve autour de 250 €. Le principal point faible est le système de rangement des lunettes, jugé peu pratique.
