When shopping for luxury cashmere, you’ll often come across terms like 2-ply, 4-ply, and even 8-ply. But what do these numbers really mean? 

What Does Ply Mean in Cashmere?

Ply refers to the number of individual yarns twisted together to make the strand that is knitted into your garment. Think of it as the sweater’s DNA. A 2-ply yarn uses two strands twisted together; 4-ply uses four; 8-ply uses eight, and so on.

  • 2-Ply: Lightweight, breathable, ideal for layering and year-round wear.
  • 4-Ply: Medium weight, cozy yet versatile, perfect for autumn and winter staples.
  • 8-Ply: Heavyweight, luxurious, made for true cold weather or as an heirloom piece.

And What About Gauge?

Gauge measures the number of stitches per inch. A higher gauge means a finer, lighter knit; a lower gauge means a denser, chunkier fabric. Ply and gauge work together—an 8-ply knit at a low gauge creates a chunky, substantial cardigan like our Bruce Shawl, while a 2-ply high-gauge crewneck feels featherlight yet warm.

Ply & Gauge Comparison

Ply & Gauge Comparison
Ply Gauge Warmth Best For
2-Ply High (12–14) Light Layering, spring/fall, office wear
4-Ply Medium (7–10) Medium Everyday winter sweater, versatile staple
8-Ply Low (5–7) Heavy Cold climates, heritage pieces, statement knits

Which Ply Should You Choose?

If you want a year-round layer, choose a 2-ply knit like our Classic Crew. For a do-it-all winter sweater, 4-ply pieces such as our Sport Crew strike the balance. And when you’re ready for a statement heirloom, the 8-ply Bruce Shawl is the ultimate in Scottish cashmere craftsmanship.

Is higher ply always better?

Not necessarily. Higher ply means thicker and warmer, but not “better.” It depends on the climate, season, and how you like to layer.
