The similarity between Domo Champion Ascari 4G and 5G is that both qualities do not require performance infill to play well on. However, there are a few differences. Domo Champion Ascari 4G always requires sand infill, while Domo Champion Ascari 5G theoretically does not. For extra stability and depending on local regulations, it is optional to add some sand to the Domo Champion Ascari 5G. Another difference is that DomoChampion Ascari 5G is approved according to EN 15330-1, NFP90-112 and DIN and RAL, depending on the specifications chosen. In addition, the Domo Champion Ascari 5G is fully recyclable in a closed loop, as it is a standard product with Domo Infinitum backing. If you also want your Domo Champion Ascari 4G to be renewable, you can ask for one with Domo Infinitum instead of latex backing when ordering.
