So far our tests clearly showed the problem and the fact that this extremely fast degradation is mainly due to UV exposure and we managed to exclude many other factors like abrasion, heavy loads (tandem), intensive use (decade of thousands of bounces) and humidity (some extremities of the tested lines weren’t damaged while they encountered the same humidity than the center). Unfortunately we are still investigating because we didn’t manage to identify clearly the causes of this phenomenon. By the information provided by our supplier, after the covid world supply chain’s crisis and then with the Ukraine war, in 2023, a change of sources of the origin of raw materials was implemented. The new materials are strong when brand new, but coming from our tests, less resistant to UV. Such degradation has never been measured by any of our suppliers. Nobody can see a difference in the raw material, not even the weaving supplier since performances when NEW, are compliant with ISA standards. In order to even better and quicker catch a possible strong degradation of UV, we are setting up some additional, fast UV validation testing for all future webbings and concerned products. We want to thank Gaelle and Alexian for their contribution, and apologize deeply for our handling of the situation and the unwilling risks we exposed some of our customers to.
