Engineered for superior comfort, our Biofuse Earplugs have an ergonomic, patent-pending design that’s shaped to the ear canal for an ultra-comfortable, secure fit during your workout. Easy to insert and remove, they prevent water from entering your ear. ‘R’ and ‘L’ markings allow you to easily identify left and right earplugs, while the unique clip-together system floats in the water for easy location.
