Super S Wool Numbers (Super 100s, 120s): What Private-Label Briefs Should Say
Write Super S as a fineness number tied to micrometres, not as a marketing adjective. The S-number indicates wool fibre fineness by maximum diameter. Under the scale summarized for the IWTO Super S Code of Practice, Super 100s corresponds to a maximum fibre diameter of 18.75 micrometres; Super 80s is 19.75 µm and Super 120s is 17.75 µm, with the published range running from Super 80s (19.75) to Super 250s (11.25) (S number (wool), Wikipedia).
In current use, Super means pure new wool (with blend rules described on that page). Do not invent mill brands or prices in the brief.

| Super S target | Super 100s (max 18.75 µm) — or the S-number you actually want |
| Composition | Pure new wool vs allowed blend, as you and the mill label it |
| Cloth ID | Mill quality code + colour + lot |
| Mass | Numeric g/m² or oz/yd² if required |
| Factory gate | Fabric confirmed before sample 7–14 days |
