Parka vs Jacket vs Coat - What is the difference between a coat and a parka jacket?
A parka is a longer, insulated outer garment designed for extreme cold, while a jacket is typically shorter, ending at the waist or hips, and suitable for milder weather or layering. A coat is a broader category for any outerwear that falls below the waist and is generally warmer than a jacket but can vary widely in style and warmth.
