Loro Piana Grade Cashmere
Definition
Baby Cashmere sourced exclusively from the underbelly of Hircus goats at 14–15.5 microns fibre diameter — the finest commercially available cashmere grade. Loro Piana has been the primary buyer and grader of this material since the 1990s. Standard cashmere grades run 16–19 microns; the finer the micron count, the softer and less prone to pilling the fabric.
Why it matters for dupe shopping
When comparing cashmere alternatives, ask for the micron specification. Products marketed as 'luxury cashmere' without specifying micron count typically use 18–19 micron fibre. At this grade, pilling begins within one to two seasons under regular wear. Loro Piana-grade fibre (14–15.5 microns) resists pilling for 3–5+ years — a meaningful longevity difference that changes the cost-per-year calculus.
