Meet the Bouclier Visor: a helmet-mounted visor that shades your entire face to provide 98% UV protection. It is easy to install and detachable. Bouclier lets you choose the degree of coverage. It eliminates the need to constantly apply sunscreen and won’t block your vision.
Bouclier should work with most visorless helmets. It pivots up and down and can be removed easily. More information is available on Kickstarter.
