This legend of downhill racing and BMX events worldwide now expands with a polyacrylite model that won’t let you down. You get the same premium safety and comfort as the carbon and composite models, just at a more friendly price.

Thanks to its attention to detail, the D4 is not only the most sought-after helmet in the discipline, but also proof that quality doesn’t always have to be measured in kilos of money.
