The complete system. One order.

Glasses: most glasses fit fine under the helmet with the AR Optics, progressive lenses included. Our founder rides with glasses himself. The display is projected at distance, so you read it like the road, not like a screen. Very bulky temples or wide frames can get tight at the sides, which is rare; if the outermost position still touches your frame, you have 30 days to return. Unsure? Send us a photo of your glasses.

About 2 kg with everything on: helmet, electronics, battery and AR Optics, a little less in the smaller shells and about 75 g less without the AR Optics.

Measure your head circumference 2.5 cm above the eyebrows. Fits a touch tighter than a stock Nexx X.WST3. Between two sizes? Take the larger. Head shape: medium oval. Three shells: XS–S, M–L, XL–3XL. To check the fit before ordering, try a stock Nexx X.WST3 at a Nexx dealer. Ours fits a touch tighter.
