## Long description

The nils extreme MT311 black helmet in size XS (48–52 cm) is a compact protective headgear designed for urban sports and everyday active transport. It offers basic impact protection suitable for cycling, skateboarding and similar activities where lightweight coverage and a secure fit are priorities.

The helmet’s small-size shell is optimized for head circumferences from 48 to 52 cm and provides a snug, stable fit without excessive bulk.

Key specifications
Size: XS, fits head circumference 48–52 cm
Color: Black
Ventilation: Multiple ventilation openings for airflow
Fit system: Adjustable retention mechanism for secure fit
Design: Low-profile urban shell for everyday use
How to use
Place the helmet on the head so that the front rim sits approximately two finger widths above the eyebrows. Adjust the retention system until the helmet feels snug and stable without painful pressure. Fasten and adjust the chin strap so it forms a V-shape under each ear and allows one or two fingers between strap and chin. Check vent alignment and adjust position for comfort before each ride. Replace the helmet after any significant impact, visible damage, or if the fit system no longer secures the helmet reliably.
Usage recommendations
Use the helmet for activities matching its protection level: city cycling, skateboarding and similar urban sports. Avoid using it for high-speed motorized activities or specialized sports that require certified, higher-performance helmets. Store the helmet away from direct sunlight and high temperatures to preserve shell and padding materials.
