There is a little bit of evil in all of us and the best way to express it is by snapping on the Horns Add-on to your EGG helmet. The horns pack includes a pair of red, white and black horns.
EGG add ons are made of premium soft rubber and can be snapped on the helmet through the skin. They pop-off in the event of an impact.
