The B2 Norwestern is the model you want for optical clarity in flat light and all daytime conditions.  We're talking about an orange based lens with a beautiful mirror blue finish! The Norwestern is great in all conditions from the cloudiest snow and fog days to the sunniest of days! The optical clarity and contrast is beyond compare especially when the going gets tough on the worst days.

The B2 is designed to fit over your glasses and has an easy interchangeable lens system with detachable strap.
