Materials guide
Is Wool Plastic-Free?
Yes. In our glossary, wool is a Tier 1 material (all natural): sourced directly from nature, free from plastics and synthetic processes.
About wool
Wool is a natural protein fiber obtained from the fleece of sheep and other animals, including camelids (alpacas, camels, llamas), goats (such as cashmere and mohair goats), and rabbits (like angora). It's known for its durability, insulation properties, and ability to absorb moisture without feeling wet.
Wool fibers are crimped, elastic, and can be spun into yarn or woven into textiles. It's widely used in clothing, blankets, carpeting, and other applications where insulation and comfort are desired. Wool is also naturally flame-resistant, making it a great choice for mattresses.
Wool is classified based on microns – a measurement of the thickness of a wool fiber. A wool with a low micron is softer to the touch than a wool with a larger micron. For perspective, the average human hair is around 50 microns, whereas wool will generally range from 10-25 microns.
Below is a non-exhaustive list of different kinds of wool.
Merino
A soft and fine wool fiber obtained from the fleeces of Merino sheep, renowned for their gentle nature and adaptability to diverse climates. It is characterized by its exceptional softness, breathability, and odor-resistant properties.
Uses: Popularly used in base layers, sweaters, socks, underwear, activewear, and even home textiles.
Alpaca
A soft and warm fiber derived from the fleece of alpacas, South American camelids known for their gentle nature and dense coats. Renowned for its warmth-to-weight ratio, superior softness, durability, and natural moisture-wicking properties (absorbs the least amount of moisture compared to other wools).
Uses: Commonly used in sweaters, scarves, coats, blankets, home textiles, and various forms of outdoor activewear.
Good to know: Alpaca wool is lanolin-free, making it hypoallergenic and comfortable for those with wool sensitivities. The alpacas are typically raised in free-range environments with low environmental impact. Alpaca farming practices generally support biodiversity and land conservation.
Cashmere
A luxuriously soft and insulating fiber obtained from the undercoat of cashmere goats, native to high-altitude regions like Mongolia and China. Renowned for its unparalleled softness, warmth, and lightweight feel.
Uses: Popularly used in sweaters, scarves, hats, gloves, and blankets.
Mohair
A luxurious, versatile textile fiber derived from the fleece of Angora goats, renowned for its softness, warmth, and durability.
Use: Primarily used in luxury clothing (sweaters, scarves, hats), accessories, and home textiles (blankets, throws, rugs, upholstery).
