Protective Helmet nils extreme MTW001 size M (55–58 cm) blue

nils extreme MTW001 size M (55–58 cm) in blue is a ready-to-wear protective helmet designed for recreational and urban activities such as cycling, skating and similar transport or leisure use. The helmet provides fitted coverage for medium head circumferences and is intended to reduce the risk of head injury by absorbing and distributing impact forces. Its low-profile design and ventilation openings balance protection with everyday comfort for commuting and short rides.

Advantages

The helmet combines a contoured shell with internal impact-absorbing foam to provide reliable energy dissipation on impact while maintaining a lightweight feel. Adjustable retention and a secure chin strap ensure stable fit across the stated size range. Ventilation channels help regulate airflow to reduce heat buildup during activity. The visible blue finish supports easy recognition in urban environments.

Suitable for

• Urban and recreational cycling
• Skating, rollerblading and similar wheeled sports
• Short commutes and last-mile micro-mobility
• Leisure outdoor activities where head protection is advised

How to use

Place the helmet on the head so the front edge sits just above the eyebrows and adjust the retention system until the helmet feels snug but comfortable.
