These sport straps are great for running or everyday wear. They are light and thin but sturdy. I ordered the 2 pack for my Dad so he can keep a spare in the car or on a different pair of glasses. They fit his sunglasses perfectly and don't slip off. They are comfortable to wear and keep him from losing his sunglasses while he's out and about.
