Casual jackets Casual jackets in army parka style are extremely practical, and they look great, too. Heavy cotton or cotton blend fabric makes these jackets virtually indestructible. Important: In spite of the very sturdy fabric, these are not motorcycle jackets. The Louis range of casual wear also includes softshell and fleece jackets. If you're in any doubt about size, you can order two different sizes from Louis online and try them on. Louis will take back any item that does not fit or which you do not like.
