Hello, the product is designed with comfort in mind. For you to feel maximum comfort while driving, the interior structure needs to breathe. This air circulation is ensured by the stitch canals in the existing patterns on the product. Therefore, we recommend using a saddle cover (rain cover) in heavy and torrential weather conditions. Otherwise, there may be very little water absorption from the seam channels. However, after this, the product dries quickly, does not smell, and does not experience any deformation in its form. The product is made entirely of artificial leather. Leather surfaces are waterproof; only a limited level of absorption can occur through the stitching channels.
