Depending on the activity, choose a raincoat that has the appropriate room and length required for the day. “Try to find options that fit comfortably and offer range of motion, but are not too loose that you have excess material swishing around,” Canon says.  For outings like walking or hiking, a hip-length coat with room for layers is a great choice. For high-intensity activities, opt for something cut closer to the body and streamlined for rapid arm movements. A longer coat is ideal for when you’ll need added coverage against high wind, side falling rain, and splashes. Customize your fit with a coat that has drawstrings at the waist, hem, and hood.
