Always in search of performance.

The D4 Composite helmet pushes back the limits with its shell designed from aerospace materials. The result is a featherweight of just 1050 grams, with no compromise on robustness.

In terms of safety, the Mips® C2 system provides extra protection in the event of a fall, by limiting rotational forces. For optimum comfort, air flows efficiently through the shell and lining, keeping your head cool even when you're exerting yourself.

X-static® and XT2® foams, which are both antimicrobial and anti-odour, ensure that the interior is always fresh and pleasant, outing after outing.

This helmet is designed for cycling use only, including competition. It is not suitable for motorbike use.

It is possible to adjust the size of the helmets by changing the internal foams. For example, if you want a size smaller than S, you can opt for XS foam. Conversely, to obtain a size slightly larger than M, you can use L-shaped foams.

Please note: there are three different shell sizes (XS-S, M-L and XL-XXL) so foams are only compatible within the same shell size.
