Just in: MET Sine Thesis road helmet

We’ve just returned from a visit to MET’s headquarters in Italy, and managed to score a production version of the company’s long-awaited new road helmet, the Sine Thesis for testing.

According to Matteo Tenni, MET’s product manager, the goal of the £179 Sine Thesis wasn’t simply to create an expensive lightweight helmet, but to “have a very ventilated helmet with very few points of contact between the head and the helmet.”

The key to the new design is the integrated composite exoskeleton (ICE). It's made out of semi-flexible nylon based plastic and MET claims it will help carry air inside and through the helmet, thus keeping the rider’s head cool.

Matteo Tenni says the vents are optimised to draw in as much air across the head as possible, no matter how fast you're going: “The helmet will help to keep the rider’s head cool when riding fast, and also when the rider is climbing at low speed."

The gel-based spotting system reduces the contact between the head and helmet to 20% : the gel-based spotting system reduces the contact between the head and helmet to 20%

MET have done away with the ubiquitous ‘cloth’ or Coolmax helmet padding and have opted for a gel strip/spot padding system, which we can see other helmet manufacturers jumping on very quickly.

The gel-based spotting system reduces the contact between the head and helmet to 20% (compared to 60% on the current Stradivarius road helmet, for example), and doesn’t retain heat so it’s more comfortable to wear too. Unlike cloth-based padding, the gel doesn’t retain sweat either, so no more rides putting back on a soggy, smelly helmet.

At first we wondered about the gel strip which covers the forehead section of the lid - surely the sweat would run down into the riders’ eyes? Nope, once on the head, the strip forms one line which carries sweat around the forehead, away from the eyes.

Look out for a full review of the MET Thine Sesis in Cycling Plus issue 223, (out on May 1st).

  • I would recommend the Sine Thesis to anyone looking for a new helmet. It is very comfortable, very cool, and very light. I have found the combination of superb ventilation and gel pads has kept the inside of the helmet nice and dry on even the hottest days: No need now to suffer the cold damp foam padding around your head after the coffee shop stop on the weekend ride.

    If, like me, you also care about who gets your money and what they do with it, you might be reassured by the company behind the Sine Thesis. Met are a rare company indeed: All production, research and development, and design is still based in Europe, in the north of Italy, providing valuable local (EU) jobs. They have an active environmental program too. Their Low Impact On Nature (L.I.O.N.) sustainable development program provides policy guidelines for all their business activities. You can read about all this on their web site.

  • I like these helmets, these are so cool and very safety for a smooth and careful drive. Thanks for your support about these meaning full article. It's an awesome article. Cheers!
