MET Trenta 3K Carbon Road Bike Helmet


The Trenta 3K Carbon is the most advanced cycling helmet MET have ever made. Delivering unprecedented levels of performance, this helmet is a vital companion for serious riders with a competitive spirit. MET’s 3K Carbon Technology is what helps this helmet outperform any other currently on the market. The carbon’s elastic modulus allows MET to reduce the density of the EPS foam by 20% without affecting its capacity to absorb energy. The parallel ‘ribs’ are linked from the centre of the helmet by a carbon cage embedded into the liner, making it dramatically lighter compared to traditional construction.



  • In-mould polycarbonate shell with EPS liner
  • 3K Carbon cage embedded into liner
  • Safe-T Orbital fit system
  • Hand washable Air Mesh comfort pads
  • Air lite straps and adjustable divider
  • Reflective rear decals
  • Includes soft helmet bag
  • Weight: 215 g (size M)
  • 19 vents
Mr Febriansyah Airy, fast and looks good! What more can you ask for?
Mr Febriansyah One of the best helmets out there! Very airy and light, not forgetting to take into account the aerodynamics part as well! No regrets!
Mr Hu Great helmet, fast and nice looking
Mr Lim The helmet is light and comfortable for me. Very suitable for the hot and humid climate in Singapore.
Austin Very lightweight and airy when riding, and with a great fit. As comfortable as any helmet I have tried - great pads and adjustable on the move.
Robert This is the most comfortable helmet I’ve ever had.
Nic Perfect fit , good price from Merlin, like the adjustment system, unless my head changes shape I won’t need to look for another.
Mr KAWABE Very light, well-fitted, and aero. Simply put, GOOD.
Mr Shoon Packaged with huge bubble wraps in the box with the bottles I bought. Happy with the helmet purchase. Super good price on Merlin after comparing numerous sites. Helmet is light, comfy and comes with a good padding and ventilated bag. No MIPS wasn't a concern to me even at this price point as it give a floating feel and makes the helmet bigger which is not to my liking.
Mr Rayner Doesn't feel like your wearing a helmet. My old helmet was a Kask vertigo 2.0. This has alot smaller profile, alot lighter. The band tightens around your head which if too tight can cause a head ache. Also the front chin straps are further towards the rear of the helmet which suits me fine. The chin strap is soft enough although I prefer the kask chin strap. Have ridden in 30 c temps so far and haven't over heated, air flow seems fine.
