The LAPORTE ® 2004 N.G. clay is testimony to the ecological commitment made by the LAPORTE ® group to limit any harmful impact on our ecosystem using environmentally friendly materials such as bitumen.  It maintains all the performance and qualities of LAPORTE ® clays due to a researched design studied to accompany all disciplines including Olympic. The design of the LAPORTE ® 2004 clay guarantees No-Birds of less than 1 % with a structure sufficiently strengthened in order to enable throwing distances of 100 metres while maintaining the fragility necessary to break on shotgun.
