When you hear the word "turtle-necks", you may automatically think of the classic style of sweater with a high, rolled neckline. However, there are many synonyms and alternative names that can be used to describe this type of garment. Some common alternatives include roll-necks, mock-necks, cowl-necks, and funnel-necks. Each of these words describes a slightly different style of neckline, but all share the same general shape and purpose of providing extra warmth and coverage around the neck. Additionally, these sweaters can be found in a variety of materials, from classic wool to lightweight cotton blends, allowing for year-round wear.
