You should avoid getting a leather bag wet. A good quality leather bag will not be affected by a rain shower, but you should never allow your bag to become saturated with water. If your bag does become very wet you should stuff it with paper towel, not newspaper because the ink may mark the lining, and replace it as it becomes saturated. Dry the bag in warm conditions but do not use high heat such as a hairdryer or tumble dryer. When the bag is dry, replenish the oils which have been washed out by using a conditioner.
