The Arena The One Goggles, now with a mirror lens, was designed to fit any face perfectly. Based on R&D data captured on the structural similarities of faces, the One is designed to fit any face perfectly. The area around the eye sockets is the most important area for engineering the perfect, no leak goggle seal. With it’s softer tissue, the eye socket needs a goggle that will adhere through non-compromised suction for all facial shapes and profiles. We have designed The One Goggle for the fitness-minded swimmer doing laps in the pool to stay fit and for the competitive swimmer training for their next challenge. Great goggle for Triathletes hitting the pool for their quick workout. Streamlined, crystal clear and performance-driven.
