Polyforms G Series fender was first produced back in the mid 1980s and immediately became the standard by which all other utility boat fenders are judged. In all this time it remains the best value for the money and outperforms similar style fenders which cost 30-50% more. No fender design has been copied more that our G Series. This entry level product incorporates the same material, valve and high gloss finish that is a trademark of our top end yacht fenders.
