The arena The One training goggles have been designed to fit most faces perfectly, based on R&D data captured on the structural similarities of faces. The area around the eye sockets is the most important zone for designing a perfect, leak-free seal for these goggles. As the skin around the eye socket is more delicate than that around the rest of the face, this area of the face needs a mask that adheres by suction without compromise. We've designed The One goggles for swimmers who want to maintain their shape while doing laps in the pool. Inspired by all our autres goggles, the clear lens and anti-fog treatment of One goggles give you forward and peripheral visual performance. With intelligent one-piece construction, integrated lenses and a one-piece adjustable nose bridge, arena's The One goggles are the only goggles you'll ever own.
