The most professional helmet to be released by renowned head protection brand Met, the Sine-Thesis makes the most of the company’s top-of-the-line safety systems.

On top of that, the helmet looks and feels great, meaning you will be comfortable when you strap it on to head out on your bike.

Your head will be kept cool via the Gel02 system that features gel pads which do not heat up as the rest of your head does. These pads also work to dispel sweat and will comfortably shape to fit your noggin.

Because of the clever design of this helmet, only about 20% of your head will actually be touching it, meaning there is plenty of room for air to get in and circulate around your skull.

A rigid composite exoskeleton comprises the outer layer of the helmet, giving a tough shell to protect you from serious impact.

Adjusting the unit is also pretty easy, thanks to the Kevlar straps and Safe-T Lite adjustable head fitting system.

On the whole, this an evolutionary helmet that will protect you well and is comfortable to wear.

The Sine-Thesis is at the top of the price range but if you don’t want to sacrifice comfort or safety, it could be an excellent option.
