This is a floating lanyard / spectacle cord made by Rapala that attaches to sunglasses or eyeglasses.
It’s made from EVA foam material, which keeps your glasses afloat if they fall into the water — perfect for boating, fishing, or water activities.
The rubber loop connector fits most temple arm sizes, and the length is adjustable to suit your needs.
Lightweight and simple, it helps prevent losing expensive polarized or prescription glasses overboard.
In short, it’s a floating eyewear retainer that gives you peace of mind during fishing and on-water adventures.
