This is for those who prefer to use a goggle strap attachment to hold your Leader C2 eyewear in place instead of relying on the temple arms and a retaining band. It gives you the option of switching between the goggle strap and temple arm configuration to meet your sporting needs.
This particular goggle strap is unique to the C2 range. It is inserted by unscrewing the temple arms, clicking the goggle strap in place and re-inserting the screw. Unlike many other attachments, this ensures that the strap will never detach from the frame and provides a robust solution for those who are concerned about the movement of eyewear during sporting activities.
