Size Medium 55-58cm  Micro believe every scooting adventure starts with scooting safely. And they believe fuss-free helmet wearing starts with good design. And what better design than teaming up with a children's character loved all over the world. Micro's Gruffalo print helmets are packed with the latest technology to make safe simple. Their magnetic buckle stops accidental pinching and helps little fingers fasten their helmet independently. The adjustable side sliders enable a snug yet comfortable fit. And the integrated light - which cleverly doubles as a sizing dial - ensures children are visible when out and about in the deepest darkest wood. Happy heads wear Micro helmets.
