nils extreme helmet MTW001 size M (55–58 cm) mint — bicycle and urban commuting helmet

nils extreme helmet MTW001 size M (55–58 cm) in mint is a bicycle and urban commuting helmet designed to provide reliable head protection for everyday rides. The model features a standard medium fit for head circumferences between 55 and 58 cm, a lightweight shell construction and ventilation typical for this series to balance safety and comfort during short commutes or longer leisure cycling sessions.

Advantages

The helmet combines a compact, urban-friendly design with shock-absorbing construction to reduce impact forces in case of a fall. Its lightweight build reduces neck strain during extended use while ventilation channels help maintain airflow and reduce heat buildup. The adjustable fit system ensures a stable position on the head and simple on-the-go adjustments for varied layering (caps or thin hats) and seasonal use.

Suitable for

• City commuting and daily travel by bicycle
• Short to medium-length leisure rides
• Transport on bike paths and mixed urban traffic
• Students and commuters who need a dependable, easy-to-use helmet

Key specifications

• Size: Medium fit for 55–58 cm head circumference
• Color: Mint
• Intended use: Bicycle and urban commuting
• Construction: Lightweight shell with internal impact-absorbing liner
• Ventilation: Multiple airflow channels for heat dissipation
• Adjustment: Rear fit adjustment mechanism for secure positioning

How to use

Place the helmet on the head so it sits level and covers the forehead without tilting back. Adjust the rear fit mechanism to obtain a snug but comfortable hold, and fasten the chin strap with enough tension to prevent excessive movement while allowing normal jaw movement. Before each ride, inspect the helmet for visible damage or cracks and ensure straps and buckles are functioning. Replace the helmet after any significant impact or when signs of wear compromise protective elements.

Usage recommendations

For effective protection, ensure the helmet is the correct size (55–58 cm) and that straps form a Y-shape around the ears. Clean with mild soap and water and avoid solvents or strong detergents. Store the helmet away from direct sunlight and extreme heat to preserve material integrity. Use this helmet for urban cycling and commuting where comfort, ventilation and a medium fit are priorities.
