What are
Super Numbers?
When investing in a tailored suit, you'll often hear terms like Super 100s or Super 150s thrown around. These numbers may sound like marketing buzzwords, but they actually have a specific meaning rooted in the fineness of wool fibers. This guide will help you navigate the world of Super numbers and understand how they impact the look, feel, and longevity of your suit.
What Are Super Numbers?
Super numbers refer to the fineness of the wool used in the fabric. The wool is measured in microns—its diameter determines the Super rating. A Super 100 fabric contains wool fibers with a diameter of about 18.5 microns, while a Super 150 fabric uses even finer fibers, around 16 microns. The higher the number, the finer the wool, and thus the softer and smoother the fabric feels.
Note: Super numbers don’t measure the weight of the fabric but the fineness of the wool fibers.
How Super Numbers Affect Your Suit
Durability
The lower the Super number, the thicker and sturdier the fibers. This makes fabrics like Super 100s and 120s better suited for everyday business wear. Fabrics with higher numbers, such as Super 150s and above, are more delicate and can wear out faster, making them ideal for special occasions but not for daily use.
Softness and Comfort
Higher Super numbers feel incredibly luxurious to the touch. A Super 180 suit, for example, will feel softer and lighter than a Super 100, but that softness comes with a trade-off in durability.
Drape and Appearance
Finer fabrics tend to drape better on the body, giving you a sleek and polished look. However, they can be more prone to creasing, which is something to consider if you're looking for a suit that travels well.
Pros and Cons of Different Super Numbers
Super 100–120
Pros: Durable, wrinkle-resistant, and versatile. Suitable for everyday business wear or formal settings where longevity is a priority.
Cons: Not as soft or luxurious as higher Super fabrics.
Best For: Business suits and all-purpose garments.
Super 130–150
Pros: Strikes a balance between softness and durability. Offers a refined appearance without being too delicate.
Cons: More prone to wear and tear than lower Supers, but still versatile.
Best For: Formal and semi-formal suits, weddings, or events where comfort and polish are equally important.
Super 160 and Above
Pros: Extremely soft, lightweight, and luxurious. The pinnacle of sophistication in tailoring.
Cons: Delicate, prone to wrinkles, and not suited for frequent wear. These fabrics are also more expensive, often reserved for bespoke tailoring.
Best For: Special occasions like weddings, galas, or high-end evening wear.
FAQ: Everything You Need to Know About Super Numbers
Is a Higher Super Number Always Better?
No. While higher Super numbers feel more luxurious and look sleeker, they aren't necessarily better for every situation. High Super fabrics (Super 160 and above) are more delicate and prone to wear, making them less suitable for daily wear.
How Do Super Numbers Relate to Fabric Weight?
Super numbers measure the fineness of the wool, not the weight of the fabric. You can have a lightweight Super 100 or a heavier Super 180 fabric depending on how it's woven. Understanding both weight and fineness helps in choosing the right fabric for your needs.
How Do You Care for High Super Number Fabrics?
Higher Super fabrics, like Super 160 or 180, are delicate and should be handled carefully. Avoid frequent dry cleaning, as this can wear down the fibers. Use suit bags and wooden hangers to maintain shape, and brush your suit after each wear.
How Are Super Numbers Determined?
Super numbers are based on the fineness of wool fibers measured in microns. The finer the wool, the higher the Super number. This is why higher Super fabrics feel softer and smoother.
Should I Prioritize Super Numbers Over Other Factors?
No, Super numbers are just one factor in choosing fabric. Construction quality, fabric weight, and your lifestyle are equally important. A well-made Super 120 suit could last longer and look better than a poorly constructed Super 180.
How Do Super Numbers Affect the Environmental Impact?
Lower Super fabrics tend to be more durable, meaning they last longer and require fewer replacements. If sustainability is a concern, choosing a fabric like Super 100 or 120 might be more eco-friendly than opting for a higher Super that may wear out sooner.
Choosing the Right Super for Your Needs
It’s essential to choose a Super number that fits your lifestyle and the occasion for which the suit is intended. If you need a durable suit for regular office wear, opt for Super 100-120 fabrics. For special events or seasonal pieces, a higher Super number like 160 or above can offer a touch of luxury—just be prepared to handle it with care.

Conclusion: It's Not Just About the Super Number
While Super numbers give you a useful gauge of a fabric's fineness, they aren't the sole factor in choosing the right suit cloth. Construction quality, fabric origin, and how the suit is made all play significant roles in the final product's durability and appearance.
