The Speedo Biofuse Reflex Goggle is intricately designed for unmatched performance. Its flexible frame contours to the face for a snug fit that's very comfortable. Swimmers will enjoy next-level visual clarity via crystal-clear anti-fog lenses with an extended peripheral view. A cushioned, comfortable and universal fit is made possible by super-soft seals with a ridged design that contours to the shape of the eyes. Adjustment is a breeze with a newly-patented push-button mechanism that allows you to customize the fit with greater precision.
