The MT401 RAYDEN is a helmet that adapts to any terrain and riding style – from city streets to the skatepark and even demanding downhill.
- Two modes in one helmet
The removable chin guard lets you switch between full face protection and a classic helmet depending on the situation – no compromises, no need to buy two helmets. - Lightweight yet durable construction
In-mould technology bonds a tough polycarbonate shell with an impact-absorbing EPS layer, so the helmet reliably cushions impacts without unnecessarily weighing your head down.
- 21 ventilation openings in total
- Precise fit adjustment with a dial
- Adjustable strap with buckle
- Low weight, high protection
- Universal use – skatepark, downhill, city
