A grey polycarbonate lens.
The P0S lens is perfect as an allrounder with a neutral colour balance. It is a comfortable lens for driving and general fishing where seeing fish is not key to success. Offshore, saltwater boat and game fishing are all comfortable with the P0S. Comfort comes from the lens reproducing colours that are closest to what you would see with the naked eye. This lens has excellent glare reduction and light reduction which appears to the wearer as a darker tone.
