Bicycle Helmet nils extreme MT301, size S (52–56 cm), green

nils extreme MT301 is a bicycle helmet in size S (52–56 cm) with a green outer shell designed to provide basic head protection for urban and recreational cycling. The helmet offers standard coverage and a compact profile suitable for everyday commuting, leisure rides and short tours where a correctly sized and lightweight protective helmet is required.

Advantages

The helmet combines a molded outer shell and internal impact-absorbing liner to reduce the force transmitted to the head in low- to moderate-impact situations. Its size range (52–56 cm) and adjustable fit system allow a secure, stable fit for smaller head circumferences. Ventilation channels integrated into the shell support airflow to help maintain comfort during short to medium rides. The design emphasizes a balance between protection, low weight and unobtrusive appearance for everyday use.

• City commuting and short trips
• Leisure and recreational cycling
• Light urban tours and errands
• School or family rides

How to use

Place the helmet on the head so that the front edge sits just above the eyebrows.

Before each ride, check for visible damage, cracks or loose parts and replace the helmet if it shows signs of impact or excessive wear.

Usage recommendations

Use this helmet for urban and recreational cycling at moderate speeds. Replace the helmet after any significant impact and follow local safety regulations for helmet use. Clean with mild soap and water and avoid exposure to strong chemicals or prolonged sunlight to preserve shell and liner condition.
