Costa polarised glasses Mainsail XL Matte Black Blue Mirror 580G

Costa polarised glasses have been highly appreciated for many years, and not just by professional guides. The brilliance and imaging performance of these patented glasses have found many fans in fresh and salt water worldwide and the large selection of frames and tints offers the right model for every fly fisherman!

The Mainsail is a goggle with a modern design that is suitable for fishing, sailing or simply everyday life on and around the water. The frame and temples are made from an extremely lightweight yet extremely hard-wearing nylon composite material. Thanks to flexible hinges, the pressure of the temples is adapted to the shape of your head. The rubberised nose and temple pads made from exclusive Hydrolite™ also ensure a very comfortable fit and a perfect fit.

• Blue Mirror:As with all Costa lenses, the polarisation effect of these tints is impressive! The blue-mirrored lens is ideal for fishing on the open sea when the sun is particularly strongly reflected. In addition, blue and green mirrored lenses are very popular for sight fishing in saltwater when it comes to spotting bonefish, permit and the like on the flats at an early stage. The biggest advantage of these tints is that contrasts are noticeably enhanced, which not only makes it easier to recognise the bright fish on the light-coloured bottom, but also makes it easier to spot structures. When fishing at home, these tints are very good both on the coast for sea trout and on lakes for pike and other predators. Overall, the blue-mirrored lenses are slightly darker.

• 580G lenses:
  Costa's patented 580G lenses are made from the highest quality real glass. They are unrivalled in terms of imaging performance, brilliance and clarity and are also 20% thinner and 22% lighter in direct comparison to conventional lenses with polarising filters. The patented C-WALL® molecular compound gives the lenses enormous scratch resistance, so you can enjoy your 580G lenses for many years to come.
