CASHMERE KNOWLEDGE · FIBER SCIENCE SERIES
In a cashmere spec, 2/26nm means two individual yarn strands (the "2"), each spun to a metric count of 26 (the "Nm" = metres per gram of single yarn), plied together. Higher Nm = finer singles. Pair count with gauge — 2/26Nm at 7–9GG makes mid-weight pullovers; 2/28Nm at 12–14GG makes year-round refined knitwear; 2/48Nm at 14–16GG makes ultra-fine travel-weight layers.
