Is it okay to steam leather jackets to remove wrinkles?
Styleforum Top Picks
Personally I would not attempt as the heat and moisture will dry out the leather, but that being most wrinkles in casual clothes do not bother me that much. If you do try it I would suggest using as little steam as possible then hang the jacket to let it air dry. After the jacket is dry rub mink oil or another oil-based leather product to nourish the leather.
