Test exclusive to the new MET Trenta 3K Carbon

At the highest level, a helmet is no longer just a safety accessory: it becomes a strategic ally. It is precisely with this in mind that the Italian brand designed the new MET Trenta 3K Carbon, an iconic model worn by Tadej Pogačar during his triumphs in the Classics, Grand Tours, and even the World Championships. Initially reserved for World Tour pros, this helmet is finally hitting the market with improvements intended to propel it to the pinnacle of performance. We already have it tested.

With the new MET Trenta 3K Carbon, the brand is not simply refreshing an already iconic design. The model has been thoroughly redesigned to meet the demands of an ever-faster and more demanding peloton. Launched this fall, this helmet retains its sleek lines, with wide vents and a pronounced front ridge that give it an aggressive and aerodynamic look. But It is under the hull that the changes are the most radical..

MET collaborated closely with UAE Team Emirates and UAE Team ADQ, incorporating direct feedback from the riders to optimize ventilation, internal structure, and impact management. The result? A 16% increase in airflow and a 40% improvement in performance in terms of protection compared to the previous generation, crowned by a 5-star score on the Virginia Tech protocol – one of the highest for a helmet routeThe Italian brand presents this new Trenta 3K Carbon as a helmet designed for scenarios where the heat rises, the speed increases, and the margin for error melts like snow in the sun.

New architecture 

At the heart of this evolution lies the new 3K Airframe architecture, an integrated carbon cage that replaces part of the traditional EPS foam inside the helmetThis innovation creates a continuous air channel from the front to the back of the helmet, transforming the front intake into a true air intake that guides the flow towards the generous rear vents. Thanks to the rigidity of carbon fiber, the foam density is reduced without compromising shock absorption, allowing the helmet to remain relatively lightweight while offering tangible gains in ventilation and safety.

With 24 openings in total Organized around a main front intake and large rear vents, the new MET Trenta 3K Carbon excels in airflow. MET also claims to have redesigned the interior, drawing on... testWind tunnel testing ensures smooth and efficient airflow over the head. This method combines optimal ventilation in hot weather without compromising aerodynamic performance.

MET Trenta 3K Carbon: 5-star helmet

In terms of security, MET announces a 40% improvement in the management of linear and rotational impactsvalidated by testIndependent developers, notably at Virginia Tech, a global leader in the field, have contributed to this helmet. It incorporates a MIPS Air-type system, discreetly integrated into the padding to avoid adding weight, and is designed to withstand the increasingly violent crashes common in the modern peloton. Team UAE, which sends between 20 and 30 damaged helmets back to MET's R&D department annually, provided invaluable feedback for refining the material distribution and overall structure.

In terms of comfort, The new Trenta retains and modernizes the strengths of its predecessor The Safe-T Orbital adjustment system features a dial and height and occipital adjustment, allowing for a pressure-free fit, even for those with long hair or a ponytail. The thin, lightweight Air Lite straps minimize cheek chafing and dry quickly, while the side vents incorporate a goggle port that securely holds the temples in place, preventing them from being ejected by the first bump if worn over the helmet. The removable and washable Air Mesh internal padding also manages moisture effectively and contributes to exceptional stability.

Despite these technological additions, the weight remains competitive, with 251 g in size SIt's not exceptional, but very good. Available in sizes S (52-56 cm), M (56-58 cm) and L (58-61 cm), it comes in classic colors such as white, black, gray or the gray-green of our model. testAt an indicative price of € 400It is positioned in the very high-end segment, neck and neck with the flagship helmets of other brands that equip World Tour teams.

Impeccable finish

Upon taking it out of the box, The new MET Trenta 3K Carbon impresses with its refined lines and impeccable finish. The smooth finish, the precise seams between the shell and the foam, and the detailed ventilation create an immediately premium feel. Adjustments, whether to the straps or the occipital support, are effortless. It's very easy to adapt the helmet to your head shape. Once on, you immediately notice its feather-light weight, and the quality of the thin straps and the precise dial inspires confidence from the first touch. Once adjusted, the comfort is so great you almost forget you're wearing it: the Safe-T Orbital system allows you to find the perfect fit in just a few turns, with a generous range of adjustment that prevents any unpleasant pressure points. The helmet touches the head on approximately 30% of its surface, allowing air to circulate freely, resulting in a remarkable feeling of lightness and stability, even when standing or sprinting.

The compatibility with glasses is exemplary.The arms slide effortlessly into the side openings and stay in place, without noticeable conflict with various models. testes.

In truth, sHis look is even more aggressive than in the photosWith its distinctive front ridge that accentuates the helmet's sleek look once it's on the head, without creating an impression of excessive bulk, the helmet remains compact and stylish, and should appeal to many customers simply because of its aesthetics.

Noticeable ventilation

In winter, I always ride with something on my head, a canvas cap or a helmet liner, and here I have to point out that the space needed to add this extra layer is severely limited. I feel that The MET Trenta 3K Carbon runs slightly small compared to other brands. like Kask or Specialized for example.

But with the cool temperatures of this mid-autumn season, it seems difficult to wear a helmet bareheaded. Because even when covered, The ventilation system seems to shine particularly well in real-world conditions.As promised by MET, the coolness is noticeable from the first few kilometers, especially on the forehead and the top of the head, where air enters through the main vent and is easily expelled, thus preventing overheating, even though I admit I don't have testThis model is designed for the extreme conditions it is intended for. However, Even between 5 and 15°C, I could feel a difference in sensation compared to other helmets.Especially with its aerodynamic profile. At low speeds, during slow climbs, its efficiency remains impressive, with a natural airflow that cools you down immediately, even before you pick up speed. The Trenta 3K Carbon is indeed a highly ventilated helmet.

If it is impossible for us to testRegarding aerodynamics, I was able to note an airflow that appears smooth and minimizes turbulence and whistling, even under strong gusts. The sensation of gliding through the air is fluidgiving an impression of increased speed without the bulk of a more closed helmet.

In committed use, The perceived security is reassuring. The volume around the temples and the occipital coverage offer enveloping protection, the rigid shell inspires confidence, and stability on fast descents is impeccable, without vibrations or slippage. The adjustments are intuitive and only need to be set once. A downside, however, is the...absence of reflective elements on the rear, in order to ensure better visibility during outings at the end of the day.

In everyday use, the MET Trenta 3K Carbon proves practical: the included soft case provides ideal protection when transported in a bag or suitcase, and the foam padding is easy to clean after wet outings. Durability seems excellent, with few visible signs of wear after several weeks, despite friction from glasses or straps.

A helmet without compromise

The new MET Trenta 3K Carbon stands out as an uncompromising helmet for those who strive for excellence: Its exemplary finish, sophisticated ventilation, high level of safety, comfort adapted to long distances, and its image boosted by Pogačar make it a model of choice.Admittedly, its price of €400 might give pause, but on the routeThe ventilation and comfort – as well as its look! – can justify the investment.
