The S-number indicates the wool fibre thickness.
The higher the number, the narrower the wool fibre. It's regarded as an easy way to determine the quality of the fabric.
While it's true that fabrics with higher micron number tend to be softer, it's also finer and more fragile. This means that they can't hold very well at the dry cleaner.
If you are looking for the quality suit that is also durable, choose a fabric that is no higher than Super 150s. Don't get obsessed with the numbers, choose one that feels good on your skin.
At The Lancelot, we provide a wide range of fabrics for you to choose and feel before you make your decision. We'll also recommend fabrics according to your occasion and habit so you'll always look confident and feel amazing in your suit.
