The Gamma 2.0 is made for the very little ones. The childrens helmet has been specially developed for small heads. This is clear with the strategically optimally arranged ventilation openings, which keep the suns rays out, but let air in. Or the rear that has been designed flat so that the helmet provides a comfortable contact surface in the child seat or trailer. In addition, the Run System Classic Slide is installed, which allows a three-dimensional adjustment to the head. A bicycle helmet cannot be adjusted easier and more comfortable. The optional Flash Light Gamma can be retrofitted for optimal visibility at dusk or night.
