Carson Optical, ER-30(01), Gripz ER-30(01) Braided Eyewear Retainer for Larger Frames - Black Ash
Carson's revolutionary new eyewear retainers will help you get a "Gripz" on your expensive sunglasses and prescription eyewear.
Gripz® eyewear retainers, by Carson, are engineered from high-grade braided silicone that will stand up to the elements and toughest use and abuse. In fact, they've been lab tested to hold the weight of a brick, earning the seal of "Brick Tested Tough."
So whether you're biking, fishing, rafting or participating in any other vigorous outdoor activity, the patent-pending Gripz® retainers uniquely combine friction and a contracting force to provide an extremely secure hold that will keep your valuable glasses safe.
