Best cashmere sweater brands
Quality cashmere is defined by three things: fiber grade (Grade A is under 14 microns — finer than human hair, noticeably softer against skin), ply count (2-ply minimum for durability; 1-ply pills within a season), and sourcing transparency (GCS, SFA, or OEKO-TEX certification confirms the fiber quality claim is independently verified rather than self-declared).
The best cashmere comes from Mongolian and Inner Mongolian herds, where the climate produces exceptionally fine fiber. Scottish and Italian mills process much of the world's finest cashmere into knitwear with generations of craft knowledge. When comparing brands, look for ply count and micron information on product pages — brands confident in their fiber publish these numbers.

Common questions about cashmere sweaters
What makes cashmere sweaters expensive?
Cashmere comes from the undercoat of cashmere goats, combed or sheared once a year during molting season. Each goat produces around 150-200 grams of usable fiber annually — enough for roughly one sweater. The fiber then requires sorting, cleaning, dehairing (removing coarse guard hairs), spinning, and knitting, all of which require skilled labor. The combination of limited annual supply, labor-intensive processing, and the softness and warmth properties of the finished fiber justifies the price. Cheap cashmere exists but cuts corners at some stage of this process — usually by including shorter fibers that pill quickly or lower grades mixed with longer-staple fiber.
What grade of cashmere is best?
Grade A cashmere has a fiber diameter of 14 microns or less and a staple length of 34mm or more. Grade B runs 16-19 microns; Grade C is 30 microns and above. The lower the micron count, the finer and softer the fiber against skin. Grade A cashmere produces a sweater that stays softer longer and pills less than lower grades. When a brand lists "Grade A cashmere" on their product page, that is a meaningful claim — but it is worth checking whether it is independently certified (GCS, SFA, or OEKO-TEX) or self-declared.
How many ply should a cashmere sweater be?
At minimum, 2-ply. A 1-ply cashmere sweater (single-strand yarn) will pill quickly and loses its shape within a season of regular wear. 2-ply is the baseline for durability — two strands twisted together create a more stable yarn that resists pilling and holds its structure longer. Higher ply counts (3-ply, 4-ply) produce heavier, warmer sweaters suited to cold climates; they also pill less and last longer. If a brand does not specify ply count, that is often because the answer is 1-ply — ask, or check the product specifications.
How long does a good cashmere sweater last?
A 2-ply Grade A cashmere sweater, properly cared for, lasts ten to twenty years. The main causes of early failure are improper washing (hot water or machine agitation causes felting and irreversible shrinkage), moths (store folded with cedar or lavender, never in a humid environment), and pilling from friction (a fabric shaver removes pills without damaging the garment; do not pull them off by hand). Washing by hand in cool water with a wool-specific detergent, blocking flat to dry, and storing folded rather than hung will keep a quality cashmere sweater in good condition for decades.
What is the difference between Mongolian and Chinese cashmere?
Mongolian cashmere is widely considered the highest quality in the world. The extreme climate of the Mongolian steppe — cold winters, hot summers — produces goats with denser, finer undercoats. Inner Mongolian and Mongolian cashmere (sometimes labeled separately) is the standard raw material for luxury European knitwear brands. Chinese cashmere (from other regions of China) is more variable in quality. In practice, the distinction matters most at the premium end of the market; a brand that sources and processes carefully can produce excellent cashmere from any quality origin region. The certifications and the ply count matter more to the finished product than the origin label alone.
