Reviews Review: Met Sine Thesis bike helmet

Review: Met Sine Thesis helmet

Innovative features and great ventilation, but at a price

Take a look inside the Sine Thesis and you can see that Met have tried to do something a little different – there are gel pads on the various contact points instead of fabric padding. It’s a nice idea, but we found that it gives a slightly harder feel internally, especially on the top of the head, which took a bit of getting used to.

However, the gel pad on the forehead is really nice and doesn’t absorb sweat, which makes it very comfortable on long rides. It does size up small – we tested the Sine Thesis in L, which meant that it came in at a hefty 290g.

The ratchet is easy to operate, the retention system has three up/down adjustment heights, but the real stand out on this helmet is ventilation. It’s fantastic. You stay cool no matter how hot it gets.
