This lightweight helmet from Micro Scooters is decorated with a charming owl design and has been especially designed to give you all the safety features your child will need. It's perfect for micro scootering, cycling, skateboarding, roller skating or any activity where the head requires protection. With extra padding for comfort and safety, the helmet has an adjustable spin dial for the very best fit and air vents for optimal ventilation. This medium size fits 53-57cm. Please choose the size carefully after measuring your child's head at its widest point (about an inch above the eyebrows). Warning: Make no modifications to the helmet. Helmets can be seriously damaged by substances such as solvents, paints, adhesives and cleaning solutions. The helmet is made almost entirely of polystyrene and may be easily penetrated by sharp objects. No protective headgear can protect the wearer against all unforeseeable impacts.
