What the Super Numbers Mean
A book of cloth opens to the same page in every showroom in the world: a small printed number, written as Super 110s, Super 130s, Super 150s, sometimes higher. It is the most cited and least understood number in tailoring. Most men read it as a quality grade. It is, more precisely, a measurement — and learning to read it is the difference between choosing cloth by its label and choosing cloth by what it will actually feel and wear like on the body.
The Super number describes the fineness of the wool fiber used to spin the yarn, measured in microns. Super 100s is roughly 18.5 microns; Super 120s, 17.5; Super 150s, 16; Super 180s, around 14; Super 200s, around 13.5. The scale was standardized in the early 1990s by the International Wool Textile Organisation. A finer fiber produces a smoother, lighter, more lustrous cloth with a softer hand and a more fluid drape. A coarser fiber produces a heavier, sturdier cloth built to absorb more wear.
What a higher Super offers
Higher Super numbers — the 150s, 160s, 180s, 200s — are the most luxurious cloths the wool trade produces. The fiber is exceptionally fine, the surface carries a quiet sheen no lower count can imitate, and the cloth moves with the body in a way that a Super 110s worsted does not. A man who has worn a Super 180s suit knows the difference within the first hour. The cloth sits lighter on the shoulders. It catches light along the lapel. It releases creases as the wearer moves rather than holding them.
A finer fiber is, by physics, less robust than a coarser one at the same construction. The cloths reward proper rotation — worn alongside a working worsted or two rather than as a daily commuter — and they reward construction choices that build substance back into the cloth. Which brings us to ply.
Ply, and why it matters at the high end
Ply describes the number of strands twisted together to form each thread. A two-ply cloth uses two strands in both the warp and the weft, producing a denser, more resilient cloth than a single-ply at the same fiber count. A three-ply, less common at the top of the market, adds further substance. The combination of a high Super number with a multi-ply construction is how the trade builds a luxurious cloth that also lasts — the fineness of the fiber for the hand and the drape, the additional ply for the structure that single-ply at the same count cannot provide.
Our house cloth: Enzo Sartori
Our signature cloth is woven by Enzo Sartori. The Sartori signature line sits where the trade is most exacting — Super 160s, Super 180s, and Super 200s, all of it engineered in two-ply and three-ply constructions. The pairing is deliberate. The high fiber count delivers the hand, the drape, and the quiet visual depth that distinguishes the cloth from anything in a working weight. The ply construction gives it the structural integrity that the conventional reading of high-Super cloth would not predict.
The Sartori cloths are the right answer for the commission that justifies them — the wedding suit, the dinner jacket, the navy worsted a client wants to feel different from the rest of his wardrobe the moment he puts it on. A man who builds a meaningful suit in Sartori 180s is not commissioning a delicate object. He is commissioning the luxurious version of a serious garment.
Matching the cloth to the wardrobe
The right Super number depends on where a suit sits in the wardrobe and how often it will be worn. A first business suit, worn several days a week, asks for a Super 110s to Super 130s in a twelve or thirteen ounce worsted — a cloth built to hold its press through repeated wear. The second or third suit, worn less often and intended to sit at a higher register, is the natural place for a Super 150s. The dinner jacket, the wedding suit, the occasion piece commissioned to be the finest thing in the closet — these are the cloths for which the Sartori 180s and 200s were built.
What to ask for
The most useful question to ask before commissioning a suit is not what Super number it is. The right question is what cloth weight, weave, ply construction, and finishing the bunch describes, and how those choices match the use the garment will see. A clothier who answers in those terms is thinking about the garment. A clothier who answers with the Super number alone is selling cloth by its label. The numbers are useful. They are part of the sentence, not the whole of it.

On Patterned Cloth: A Field Guide
Solid cloth is the foundation of a working wardrobe. Pattern is what a man adds once the foundation is sound. Five patterns do most of the work in tailoring — the glen check, stripes, the windowpane, the herringbone, and the birdseye. Each is built differently, each reads differently on the body, and each belongs to a particular register. The five together cover most of the patterned cloth a serious wardrobe will ever ask for.
On Cashmere: Grades, Origins, and What Quality Looks Like
Most men own a cashmere garment. Few can, on inspection, tell whether the garment they own is good cashmere or merely cashmere. The fiber has been so democratized — by the mall brands, by the e-commerce labels, by the seasonal sale racks — that the word itself has lost most of its meaning. The original meaning is recoverable. It requires a small vocabulary and a willingness to handle the cloth long enough to read it.
The Double-Breasted Suit, Considered
The double-breasted suit has spent much of the last forty years out of fashion, then quietly back in it, then out again. Each of these movements obscures a more durable fact: the silhouette is its own grammar, and a man who understands its rules does not need to track its returns. The double-breasted is the most architecturally distinct cut in a man’s wardrobe — and, in its proper form, the most quietly authoritative.
