Aqua Sphere's Kaiman goggle are possibly one of the best value triathlon friendly goggles on the market. The wrap around design offers superb all round vision making them not only good enough for the pool, but fantastic for racing in open water too. It's not just the vision that benefits from the shape – the hydrodynamic configuration also helps reduce drag. You get a good fit thanks to a good seal around the eye sockets. They're leak proof and stay in place well due to the easy adjust buckle system. The bridge section is flexible and allows adjustment for a wide variety of different face sizes and shapes.
