Approved by the World Karate Federation this tatami is the first bio-based mat with premium features. The innovative three-layer design of the new Green WKF Approved Tatami allow a grip on the mat and a precision of movement never before achieved by ProGame. Compared to the previous model, thanks to the bio-based core layer, it generates, at least, a 20% reduction in CO₂ emissions. The new shape of the interlocking system, with bigger undercut, ensures a level of stability never before achieved by ProGame.
