Fortis Bays

About the Product

A Universal Fit for Maximum Sports Performance

The Bays are our go-to sports frames, refined for a truly universal fit.
Spring-loaded hinges allow the arms to flex to wider heads and reduce that
pinching feeling behind the ears, while rubber tips keep them secure and
comfortable during long sessions.

The Bays range offers one of the widest lens selections in the Fortis lineup.
Each BY code below represents a specific lens tint and mirror treatment designed
to excel in different light conditions. Choose the colour that best matches your
environment and preferred viewing style.
