The guys at 7iDP aren’t afraid of eye-catching/garish hues. This lid’s looks certainly divided opinion in the office, but that’s no bad thing.


The bright orange M2 helmet (it’s available in more subtle hues too) boasts 19 vents and an easy-to-use indexed adjuster dial to get the cradle fitting just right. But best of all is the bargain price tag.

Helmet fit is subjective. We found the M2 snug, but did need to crank up the cradle quite a bit to eliminate unwanted forward movement.

In use though, it took a matter of minutes for that tighter than normal fit to be forgotten. Thanks to the 19 vents, airflow and cooling felt on par with other ‘trail’ helmets like the Bell Super 2, Giro Feature and Scott Stego.

Coverage is good, with a dropped rear to help keep your bonce intact if you do take a big spill. We walked away from our only crash during testing pretty much unscathed – though we did manage to break the M2’s peak.


All in all, it’s an impressive design – and the price makes it seriously tempting.
