Protective Helmet nils extreme MTW001, Black, Size M (55–58 cm)

nils extreme MTW001 is a protective helmet in black, designed to protect the head during cycling and recreational sports. Delivered in size M (55–58 cm), this model provides a secure fit for medium head circumferences and is intended for everyday rides, urban cycling and light outdoor activities. The shell and internal components are configured to absorb and distribute impact forces while maintaining a compact, unobtrusive profile suitable for regular use.

Advantages

The helmet combines a lightweight construction with internal impact-absorbing material to reduce transmitted forces during falls. An adjustable retention system ensures a stable fit for head sizes 55–58 cm, while multiple vents maintain airflow to improve comfort on longer rides. The low-profile design and matte black finish offer a neutral appearance that fits a wide range of cycling styles without adding unnecessary bulk.

Suitable for

• Commuting and urban cycling
• Recreational and weekend rides
• Light outdoor sports and general head protection
• Users with medium head circumference (55–58 cm)

Key specifications

• Design: Low-profile cycling helmet for recreational use
• Ventilation: Multiple vents for airflow and comfort

How to use

Place the helmet on the head so the front edge sits about two finger-widths above the eyebrows. Tighten the adjustable retention system until the helmet feels snug but comfortable, and fasten the chin strap so it sits securely under the chin without excessive slack. Check that the helmet does not tilt forward or backward and that side straps form a V-shape under the ears. Before each ride, inspect the helmet for visible damage and ensure straps and buckles function correctly.

Usage recommendations

Use this helmet for everyday cycling and leisure activities where head protection is needed. Replace the helmet after any significant impact or if you notice cracks, deformations, or compromised retention components. Clean the helmet shell and liner with mild soap and water, and store it away from direct sunlight and high heat to preserve materials and fit.
