Showing the fineness of the raw wool fibres used to create the fabric, labels such as Super 110s and Super 150s provide useful information when comparing suits. Generally, a higher number indicates finer fibres, which can give the material a softer and more luxurious feel.

However, choosing the highest number does not automatically mean choosing the best suit. Men who regularly wear suits for work or business travel may benefit more from durability and wrinkle resistance, while those shopping for formal occasions may prefer a softer and more refined fabric.

Offering a practical balance between elegance and durability, Super 110s suits work particularly well for frequent wear. Their relatively thicker fibres can better handle regular use and resist wrinkles, making them a smart option for long working days and frequent business trips.

Providing a softer, lighter feel, Super 150s delivers a more luxurious experience and an elegant drape. It can therefore work particularly well for important meetings, formal events, and occasions where a more polished appearance matters. However, finer fabrics generally require greater care to maintain their condition.

Looking only at the Super S rating can overlook other important signs of quality. Factors including the source of the wool and the way it is spun, woven, and finished can significantly influence how the final fabric looks and feels.

Checking the fabric mill can also provide useful insight, particularly when choosing textiles produced by established Italian or English mills. Ultimately, the best suit is not necessarily the one with the highest Super number, but the one that suits how it will actually be worn. For frequent travellers, durability may matter most, while finer fabrics can bring extra sophistication to special occasions.
