Merino wool comes from the Merino sheep, originally from Spain and now widely raised in Australia, New Zealand, and South Africa.

It is one of the finest, softest, and highest-performance natural fibres in the world, known for thermo-regulation, odor resistance, and luxurious comfort.

Merino is valued in both:

  • Luxury fashion, and
  • High-performance activewear

Key Fibre Properties

Fibre Diameter

  • Ultra-fine:
    • 11.5–24 microns (Merino)
    • Compared to 30–40 microns for regular wool 
  • Finer = softer, non-itchy, premium feel

Fibre Structure

  • Natural crimp → elasticity + insulation
  • Keratin protein structure
  • Cortex + cuticle layers trap air

Strength

  • Strong in both dry and wet conditions
  • Naturally wrinkle-resistant
  • Elastic and durable

Surface Feel

  • Extremely soft
  • Next-to-skin comfort
  • Smooth, luxurious handfeel

Performance Features

Thermoregulation

  • Keeps warm in cold weather
  • Keeps cool in hot weather
  • One of the best natural temperature-regulating fibres
  • Ideal for European spring/summer layering

Moisture Management

  • Absorbs up to 30% of its weight in moisture
  • Wicks sweat away from skin
  • Releases moisture to the air quickly
  • Stays dry and comfortable

Antimicrobial & Odor Resistant

  • Natural keratin structure does not support bacteria
  • Prevents smell even after days of wear
  • Popular in travel and performance apparel

Fire Resistance

  • Flame-resistant
  • Does not melt or drip
  • Safe for children’s clothing

Breathability

  • Highly breathable due to natural fibre crimp
  • Ideal for layering, workwear, and athleisure

Lightweight & Stretchy

  • Natural elasticity
  • Retains shape well
  • Perfect for fitted or elevated silhouettes

Environmental & Sustainability Attributes

Renewable Fibre

  • Grows naturally on sheep every year
  • 100% renewable and regenerative

100% Biodegradable

  • Home compost: 6–24 months (protein fibre)
  • Breaks down into nitrogen-rich soil
  • Industrial composting accelerates the process to 8–12 weeks

Responsible Farming

When sourced under standards:

  • No mulesing
  • Ethical treatment of animals
  • Biodiversity and soil protection
  • Chemical-free pasture management

Low Energy Use

  • Fibre production is animal-based, not industrial
  • Lower carbon footprint vs synthetics extending over product lifetime

Long Garment Life

  • Highly durable
  • Long-lasting quality
  • Lower impact through extended lifespan

No Microplastic Pollution

  • Zero synthetic shedding
  • Breaks down fully in soil/water over time

Fabric Characteristics

Texture & Appearance

  • Smooth
  • Soft
  • Luxurious
  • Fine drape
  • Knit and woven options both available

Drape

  • Fluid, supple
  • Premium look for luxury apparel

Handfeel

  • Soft against skin
  • No prickliness due to low micron count

Dyeing 

Dyeability

  • Excellent affinity to:
    • Acid dyes
    • Low-impact dyes
  • Takes rich, deep colours
  • UV-resistant more than cotton

Compostability & End-of-Life

  • Protein-based fibre → fully biodegradable
  • Breaks down into nitrogen-rich fertilizer
  • No toxic residues
  • Safe for soil, plants, and water systems
  • Best composting when cut into small pieces
