## Long description

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

 Users with medium head circumference (55–58 cm)
Key specifications
 Size: Medium, fits head circumference 55–58 cm
 Color: Black
 Design: Low-profile cycling helmet for recreational use
 Ventilation: Multiple vents for airflow and comfort
 Fit system: Adjustable retention for secure fit
 Construction: Hard outer shell with internal impact-absorbing liner
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.
