If the liner attachment system fails, you can still wear both components separately—the shell functions as a standalone shell pant, and the liner works as a casual pant. You can also layer them together without the attachment system, though the liner may shift or bunch during active movement. This is one advantage of 3-in-1 pants over fixed-insulation pants: even if the connection system fails, you still have two functional garments rather than one broken one.
