Do you know your types of wool?
From Shetland to merino, it can vary widely. Earlier, we covered the differences between virgin and recycled wool. Today we’ll help you understand the main types of wool, including:
- Merino wool
- Shetland wool
Quick note: Fibers are only wool if they come from sheep. So cashmere, alpaca and mohair (which come from goats and alpacas) are actually hair, not wool. Interesting, right? Now let’s get started!
This soft fiber comes from Merino sheep, mostly found in Australia and New Zealand. Merino wool is finer (or thinner) than your average wool, which makes it softer, less itchy and more flexible. Our 5th avenue throw is a great example. It’s also cool, breathable and moisture-wicking, which is why merino makes for such a good base layer during hiking or exercise. Whether you’re hot or cold, merino wool keeps you comfortable—no wonder it’s so popular!

Even within merino wool, there are several different categories. Not to get too technical, but the larger the diameter of the wool fiber, the coarser and more itchy it will be. Some wool fibers can be 25 microns in diameter or more, and your hair is 50-100 microns thick. In comparison, merino wool fibers are typically 24 microns in diameter or smaller. Fine merino is less than 19.5 microns, superfine is less than 18.5 and ultrafine merino is less than 15. For sweaters, socks, blankets and more, merino wool is an excellent (and premium) choice.
Lambswool, a hardworking and durable favorite fiber, is the finest, softest fleece that comes from a lamb’s first shearing, usually when the lamb is six or seven months old. It’s smooth, strong and flexible, plus it doesn’t need much processing. Lambswool is excellent for blankets and bedding (and allergy sufferers) because it’s hypoallergenic and resists dust mites. Like merino and all wool, lambswool is breathable and helps your body regulate temperature.
Authentic Shetland wool comes from Shetland sheep, originally found on Scotland’s Shetland Islands. Over 200 years ago, Sir John Sinclair praised Shetland wool as having “the gloss and softness of silk, the strength of cotton, the whiteness of linen, and the warmth of wool.” The fibers are 23 microns thick on average, making it generally thicker than merino. Shetland wool is known for being durable and hardy, as the climate on the northern island can get quite cold. That means Shetland wool is terrific for warm and toasty sweaters. If it’s too rough for your liking, layer it over a shirt.
This silky soft fiber comes from the fine undercoat of the cashmere (or Kashmir) goat and is known for being supersoft, delicate and luxurious. Most cashmere comes from goats in China and Mongolia. Fibers are about 18 microns in diameter, so about the same as superfine merino. It’s often expensive: Only about 25% of a cashmere goat’s fleece is used, so it takes the hair of two goats just to make one cashmere sweater. Some of Pendleton’s wool blankets, sweaters and coats contain cashmere to make the texture blissfully soft yet still warm and insulating.
Alpaca hair is strong, silky, warm and durable…plus alpacas are cute! (They’re related to llamas.) Alpacas were originally bred in South America and especially prized in Inca culture in Peru’s Andes Mountains. Their hair is hypoallergenic, so if you’re allergic to wool, try alpaca. If not, alpaca and merino wool create a wonderfully soft and light yet insulating blend. Fibers are similarly sized as cashmere and fine merino. We use alpaca yarn in some of our most luxurious sweaters.

This fiber is hair from the angora goat. It’s smoother than wool (and slightly more expensive) but not as soft as cashmere, so it’s kind of a middle ground. Fibers are 25-40 microns in diameter, roughly the same as Shetland wool and even some merino. Mohair is known to have a fuzzy texture, because the goat’s coarser outer hairs mix in with its fluffy undercoat. Like wool, it’s wrinkle- and dirt-resistant.
