The bags of the Oberwerth Hydro Line are made of specially hydrophobized leather. The hydrophobic leather is treated during the tanning process in such a way that it is naturally water-repellent for a long time. This process creates an elegant, light and particularly high-quality leather. Our hydrophobic leather is as breathable as normal leather, but has some improved properties in comparison. Because the material is hydrophobic, it dries faster and thus ensures better heat regulation. Our water-repellent leather also impresses visually, as there are hardly any water stains or stains on the surface.
