The Green Guard is a more affordable EU standard helmet. It features a red LED rear light with three light modes (2 types of blinking + permanent shining). The lights are controllable through a small button on the rear side. They work with a small included battery.
Moreover, the Green Guard comes with three strong magnets in front. The magnets can hold included magnetic sunglasses (see picture). The sunglasses are with one click removable. Transparent glasses are not available yet though.
As all our helmets, the Green Guard has an adjustable/universal size, which fits 57-62cm heads.
