Swim goggle with one-piece silicone frame that provides a good fit and protects against water leakage. They have anti-fog lenses with UV protection, as well as an adjustable strap. Available in two different lens options: the blue lens that works best for indoor swimming or in darker water, and a black lens that works best for outdoor swimming or if you want to block out light when you swim. Four sizes of nose bridge are also included for a better fit over the nose.
