## Long description

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.
Suitable for
City commuting and short trips
Leisure and recreational cycling
Light urban tours and errands
School or family rides
Key specifications
Size range: 52–56 cm (S)
Color: green outer shell
Construction: hard outer shell with internal impact-absorbing liner
Fit adjustment: adjustable retention system for a snug fit
Ventilation: integrated vents and channels for airflow
Usage: designed for urban and recreational cycling
How to use
Place the helmet on the head so that the front edge sits just above the eyebrows. Adjust the retention system at the rear and tighten the chin straps until the helmet feels secure but comfortable, with enough room to move a finger between the strap and the chin. Ensure straps form a V-shape under each ear and fasten the buckle. 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.
