Product information "Alpina Challenge D anthracite 2018/19"
As with all alpine goggles, 100% UV-A, UV-B, and UV-C protection is guaranteed in the Challenge for optimum visibility.
The Doubleflex windshield prevents fogging of the windshield as the air pocket between the panes serves as insulation. In poor light conditions, the bright lens provides good visibility. Attached helmet straps and the new comfort frame offer a super fit.
