My tip: The leather jacket and trousers before treatment gently warm up to 30 to 40 degrees Celsius quite easily with a hair dryer and the liquid oil in the microwave. Then the oil is absorbed more quickly and more deeply into the pores, makes the leather soft and you get behind no greasy fingers. When the procedure is repeated once or twice, the leather clothing is also highly water-setting. Nonetheless, you should of course when it rains have a waterproof rain suit in the luggage and can draw in case of problems.
