The Carson ER-20 Gripz Eyewear Retainer will help you get a "Gripz" on your expensive sunglasses and prescription eyewear.
Gripz eyewear retainers 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.
