The handle body of the GP3 BioKork grip consists of 40% bio cork. The material for the handle body comes from organic cultivation in Portugal and meets strict ecological guidelines. All parts of the handle are consistently manufactured with ecological sustainability in mind. The BioKork handle is the result of the Ergon initiative "GreenLab".
Project GreenLab sets new targets in Ergon’s product development with the goal to unite ergonomics, performance and ecology. It was launched by Ergon in 2010 and has produced numerous product innovations, from biocompostable packaging and organic handle compounds to the use of vegetable-grown leather from Allgäu organic cows.
