The Project 23 Carbon Full Face Helmet features a whole host of materials and technologies to ensure your head gets the finest protection possible while offering an incredibly low weight for a hard-shell lid.

Seven iDP chose a Carbon Fibre hardshell construction over the EPS foam core rather than in-moulding a light outer to a foam core, as can be found on most trail helmets. This makes it superb at absorbing impacts, prevents penetration from ground objects and, thanks to the carbon outer, weight is kept low without compromising safety.

The CRV (Crash Release Visor) is also designed to snap away in the event of a crash, reducing forces on the neck and head. It simply snaps back into place too, rather than using bolts.

The Project 23 Carbon also features the S.E.R.T. system, this acts as a slip-plane system to manage the rotational forces on your head and brain. By minimising and managing the transmission of impact forces to your brain, some 20% greater absorption than standard systems, you're less likely to suffer chronic brain injuries.

The 23 vents make this the most ventilated hard-shell full-face helmet currently available. The TF (Through Flow) Goggle ventilation ensures you always have a clear view too, keeping fogging at bay.
