The Speedo Biofuse Aquatic Swimming Earplugs are made from a multi density silicone for maximum comfort and fit. They are a ergonomic design which makes for easy insertion and removal without damaging your ears. They come with multi flange construction that reduces water in the ear. This is due to the fact that for water to penetrate in to your ear, it would have to get past 3 silicone layers, which is not going to be easy.
