Understanding Wool Super Numbers: A Guide to Quality and Luxury

When shopping for high-quality wool garments, you may have come across terms like "Super 100s" or "Super 150s." These designations, known as wool super numbers, play a crucial role in determining the fabric's quality and characteristics. But what exactly do these numbers mean? Let's delve into the world of wool super numbers to understand their significance.

What Are Wool Super Numbers?
Wool super numbers are used to denote the fineness of wool fibers. The higher the super number, the finer and softer the wool. This system was developed by the International Wool Textile Organization (IWTO) to provide a standardized measure of wool quality. The super number indicates the diameter of the wool fibers in microns; for instance, Super 100s wool has fibers that are 18.5 microns in diameter, while Super 150s wool fibers are finer, measuring around 16 microns.
