Helmet fit is a very subjective beast, but the Cosmic Ultimate's average shape should fit a lot different riders. The performance from the 210g lid was good too, with very little for us to complain about. It doesn't stand out quite like the original Mavic Plasma helmet, so the subtle stylings should please a lot of cyclists.

The Plasma, Mavic’s former top of the range road lid, looks quite chunky in comparison to this new slimmed-down model. The Mavic Cosmic Ultimate weighs in at only 210g (medium), a healthy 70g reduction.
Those figures make it just about light enough to compete with the market leaders at this price range. The internal shape is neither particularly narrow nor wide and, thanks to four size options, getting the correct size was simple enough.
Inside, a summer of sweat and hard work were easily washed away thanks to the removable padding that has stood the test of time.
The retention system, known as the Ergo Hold, is a lightweight plastic affair that held in place well and was easy to adjust mid-ride. And despite the minimal customisation as to how high or low the cradle strap sits, the Mavic Cosmic Ultimate helmet was always comfortable enough for this tester’s head.
