What unique quality does rabbit wool possess compared to other types of wool?

Rabbit wool, specifically angora wool, is known for being exceptionally light and warm. This unique combination of qualities sets it apart from other types of wool. The fibers of rabbit wool have a hollow structure, which contributes to its insulation properties while keeping the weight minimal. This makes it ideal for lightweight garments that need to provide warmth without bulk.

The lightness of rabbit wool is crucial in applications such as knitwear, where wearers seek comfort without feeling weighed down. Its warmth is also notable; the fibers trap heat effectively, making it suitable for cooler temperatures. This combination of lightweight and high thermal insulation is not commonly found in other wool types, which may be heavier and not as efficient in retaining warmth.

The other options do not accurately represent the qualities of rabbit wool. While some wools can be coarser or less warm, rabbit wool specifically excels in being both light and warm, making it valuable in fabric production.
