MET Trenta 3K Carbon (2026) MIPS – Black Matt, Size M
The MET Trenta 3K Carbon in its 2026 edition is engineered for maximum ventilation and safety – developed in collaboration with Tadej Pogačar and refined in the in-house wind tunnel «The Tube». At its core is the new 3K Airframe construction in carbon, which creates a continuous airflow channel from front to rear and boosts cooling performance by 16% compared to its predecessor. Additional protection comes from MIPS Air Node, which reduces rotational forces in crashes and earns the helmet a Virginia Tech 5-Star rating, with a 40% improved test result according to the manufacturer. In size M, the Trenta 3K Carbon weighs just 260 g and is available in Black Matt as well as additional colours. This combination of high ventilation, low weight and cutting-edge protection technology makes it a benchmark for road cycling helmets.

Technical Details and Features
The redesigned 3K Airframe construction replaces internal EPS supports with a carbon structure, creating a continuous airflow channel that efficiently dissipates heat even at lower speeds. Combined with the 24 vents, MET's comparative tests show this delivers 16% improved ventilation – with no compromise to aerodynamics. The MIPS Air Node system is integrated into the padding and redirects rotational movement away from the head, achieving 5 stars in independent testing and, according to MET, delivering 40% higher safety performance over the predecessor. The Safe-T Orbital system allows fine-tuned all-round, height and rear-head adjustment, so the helmet sits securely without creating pressure points. The Trenta was tested and optimised in MET's own «Tube» wind tunnel using thermo-sensitive dummies to analyse airflow and temperature under realistic conditions. The fully wrapped polycarbonate shell, Air Lite straps and sunglass ports round off the premium package.
Intended Use and Benefits
The Trenta 3K Carbon is designed for road cycling, gravel and cross-country riding, and really comes into its own on long climbs, hot days and intense intervals. Thanks to its highly efficient ventilation, your head stays noticeably cooler, keeping performance consistent over hours – a benefit confirmed by real-world testing. At 260 g in size M with its compact shell shape, neck strain is kept to a minimum, while the Safe-T Orbital adjustment ensures a secure fit on rough roads and gravel sections. The sunglass ports offer a handy storage spot on climbs or during breaks, and the reduced contact areas further improve the climate inside the helmet. With its 5-Star rating from Virginia Tech, the Trenta 3K Carbon ranks among the safest options in its class – ideal for ambitious cyclists across Switzerland. Available in three sizes (S/M/L) and multiple colours, including Black Matt for a subtle, timeless look.
Optional: Fit and Size Guide
Size M covers a head circumference of 56–58 cm; measure horizontally across your forehead and the back of your head, and if you're between sizes, go with the larger option. With the 360° wrap of the Safe-T Orbital system, you can fine-tune the circumference, height adjustment and occipital support so the helmet sits snugly without any pressure. A handy bonus for frequent riders: the box includes a helmet soft bag to protect the Trenta during transport, whether you're heading to training or up into the mountains. The combination of MIPS Air Node, optimised airflow management and CE certification gives you state-of-the-art protection technology that's already been proven at WorldTour level.
What the experts say
"The most significant change over its predecessor is improved ventilation: it is 16% cooler thanks to the commodious 20 vents and the 3K Airframe, which has eliminated the need for an EPS internal frame."
Aaron Borrill provides a comprehensive review of the Met Trenta 3K Carbon helmet, praising its improved safety standards (40% higher Virginia Tech scores), enhanced ventilation (16% cooler with new Airframe design), and excellent fit through the Safe-T Orbital system. While acknowledging the premium £350 price point and limited color options, he concludes it represents a worthwhile investment for serious cyclists, having personally tested it during the seven-day Gravel Burn stage race in South Africa across varied weather conditions.
"The fit was a little narrow for my head, but this is quite a personal thing; although the older Trenta 3k fit me just fine."
The Met Trenta 3K Carbon is an expensive but well-engineered road helmet that delivers exceptional safety credentials with a Virginia Tech five-star rating and improved ventilation and aerodynamics over its predecessor. While the helmet excels in build quality and performance, the slightly narrower fit may cause discomfort for some riders, particularly when wearing additional layers underneath. Overall, it's an excellent choice for riders prioritizing safety and performance, though the £350 price tag is a significant investment.

"The advertised ventilation is excellent; you can really feel the air flowing over your head and keeping you cool. The internal channel system that pulls air inwards, upwards and out through the top is clearly doing its job, and the low weight makes you really forget you're wearing it."
The Met Trenta 3k Carbon is a top-end lightweight road helmet that excels in ventilation, aesthetics, and safety with its Mips Air system and five-star Virginia Tech rating. The reviewer praised its exceptional airflow, comfortable fit with excellent adjustability, striking carbon weave design, and effective sunglasses port across extensive real-world testing. While the high price and minor issues like hair catching when removing the helmet prevent it from being perfect, it remains an excellent choice for cyclists prioritizing lightweight comfort and ventilation on climbs and hot days.
"Class leading safety rating, very well ventilated, still fast"
The Met Trenta 3K Carbon Mips is an exceptionally well-engineered performance helmet that prioritizes safety improvements over weight savings. With a five-star Virginia Tech safety rating, enhanced ventilation through carbon airframe design, and maintained aerodynamic performance, it represents a thoughtful evolution despite a 42g weight increase. The helmet excels in ventilation and safety but may not suit riders with wider head shapes due to its slender profile.
