Coats are typically thicker and longer than jackets, providing more warmth and protection from the elements. Jackets tend to be shorter in length for a sleeker look. While both can have similar features such as pockets or zippers, coats often come with hoods that provide additional insulation against cold weather.
To evoke an emotional response while making a statement on the varying functions of these garments, one could say: A coat is like your own personal armor – designed to protect you from whatever life throws at you.
