When wearing my Watch under a waterproof jacket, in the rain, the fabric activates the device. It will start talking, and haptic feedback is coming through my wrist. there is no water on the watch, and this happens with several jackets. Is there a way of preventing this? If I'm on a long walk or bike ride and my Watch is talking all the time I'm concerned that the battery will run down too quickly, and that my jacket may activate other functions that I don't want running. Thanks.
