Avoid watching your favourite pair of glasses sink to the bottom of the river with a pair of our floating sunglasses cords. If you wear prescription glasses or have a pair of sunglasses that you refuse to part with, try a floating sunglasses cord to protect them. The fully adjustable looped ends can accommodate virtually any pair of sunglasses or spectacles. These cords are 60cm in length and are fully adjustable. They are made from a very durable nylon and polyester material. These floating retainers are incredibly buoyant and can support glasses weighing up to approximately 120 grams. Suitable for almost all glasses.
