Helmet nils extreme MTW001 blue size S (52–56 cm) - bicycle/urban helmet

nils extreme MTW001 blue size S (52–56 cm) is a bicycle and urban helmet designed for everyday cycling. The helmet fits head circumferences from 52 to 56 cm and features a standard helmet construction that combines a protective outer shell with impact-absorbing inner lining to reduce the force of impacts during falls or collisions. The model is intended for commuting, short recreational rides and general urban use where a reliable, correctly fitting helmet is required.

Advantages

The helmet offers an adjustable fit system to ensure stable positioning on the head within the 52–56 cm range.

The design balances protection and low profile suitable for urban environments, and the blue finish provides visible colour identification without reflective or electronic elements.

How to use
