For a high shine finish we recommend Leder-Glös.
In adverse or wet conditions Leder-Gris Original is better, it has more leather oil and is designed to waterproof and protect the leather in tough conditions.
Regular use of Leder-Glӧs will eventually increase leather hardness, this is due to lower levels of conditioning oils. If leather shows signs of hardening or flex cracking, use a single treatment of Leder-Gris Xtreme – this will darken the colour, but it will help restore leather oils and delay the rate at which cracking will occur.
