Protective Helmet Nils Extreme MTW001-1, Size XS (48–52 cm), Blue

The Nils Extreme MTW001-1 protective helmet in blue, size XS (48–52 cm), is designed to provide basic impact protection for small head sizes. Its compact shell and adjustable fit make it suitable for recreational and light sporting activities in urban environments. The helmet offers a stable, close-fitting profile intended for cycling, skating, kick scooters and similar activities where a correctly sized helmet improves safety and comfort.

Advantages

An adjustable fit system allows the headband to be tuned for a snug fit within the 48–52 cm range. Lightweight construction and modest ventilation openings balance protection with wearability for short- to medium-duration use. The compact shape improves compatibility with backpacks and clothing during everyday urban sports.

How to use

Place the Nils Extreme MTW001-1 helmet on the head so that it sits level and covers the forehead without tilting backward.

Fasten and adjust the chin strap so it sits under the chin with enough room to insert one or two fingers between the strap and the chin. Check that the helmet does not shift excessively when you shake your head and that vision is unobstructed before use.

Usage recommendations

Inspect the helmet before each use for cracks, deformations or damaged straps. Replace the helmet if it has been involved in an impact, shows visible damage, or no longer fits correctly. Clean the shell and liner with mild soap and water, avoid solvents and high-temperature drying. Store the helmet away from direct sunlight and sources of heat to preserve materials and fit.
