The Different Types of Wool Used to Produce Clothing

Wool is one of the most versatile, durable, and naturally insulating fibers used in the textile industry. For centuries, humans have relied on wool for its remarkable warmth, breathability, and comfort. From the rugged outerwear worn by shepherds and sailors to the luxurious scarves and knitwear of the fashion world, wool continues to play a vital role in modern clothing.

But not all wool is the same.

There are many different types of wool, each with its own unique texture, warmth, softness, and performance characteristics. Some types are prized for their luxury and fineness, while others are loved for their resilience and weather resistance. Whether you're shopping for a cozy winter sweater or investing in premium outerwear, understanding the different types of wool used in clothing can help you make informed, lasting choices.

Here’s an in-depth breakdown of the most commonly used wool types in the fashion and knitwear industries:

1. Merino Wool – Soft, Breathable, and Ideal for Everyday Wear

Merino wool comes from Merino sheep, primarily raised in New Zealand and Australia. It is one of the most popular wool types used in clothing today, valued for its fine fibers, which make it softer and smoother than traditional wool.

Key Features:

  • Naturally breathable and moisture-wicking

  • Odor-resistant, temperature-regulating

  • Softer and less itchy than standard wool

  • Ideal for base layers, sweaters, socks, and activewear

Merino wool is especially popular in Aran sweaters, where it brings a modern softness to traditional Irish knitwear while still delivering warmth and structure.

2. Cashmere – Luxurious, Lightweight Warmth

Cashmere is sourced from the undercoat of cashmere goats, primarily found in Mongolia, China, and parts of the Himalayas. Known for its unmatched softness and insulating properties, cashmere is a top choice for luxury garments.

Key Features:

  • Ultra-soft and feather-light

  • Provides superior warmth without bulk

  • Ideal for sweaters, scarves, shawls, and coats

  • Requires delicate care (hand-washing or dry cleaning recommended)

Cashmere garments are typically more expensive due to the labor-intensive collection process and the small amount of usable wool produced per goat each year.

3. Alpaca Wool – Warm, Silky, and Hypoallergenic

Alpaca wool comes from alpacas native to South America, primarily Peru. Softer and warmer than sheep’s wool, alpaca fibers have a natural silkiness and are often used in both traditional and contemporary knitwear.

Key Features:

  • Hypoallergenic (contains no lanolin)

  • Naturally water-resistant and flame-retardant

  • Comes in a wide range of natural colors

  • Excellent for sweaters, coats, scarves, and blankets

Alpaca wool is celebrated for being both sustainable and luxurious, with a growing reputation in eco-conscious fashion circles.

4. Lambswool – Soft and Lightweight First Shear Wool

Lambswool is made from the first shearing of a young sheep, usually when it is around seven months old. This gives it a soft, smooth texture that is often gentler on the skin than adult sheep wool.

Key Features:

  • Naturally elastic and breathable

  • Hypoallergenic and ideal for sensitive skin

  • Lightweight yet warm

  • Commonly used in fine knitwear, baby garments, and scarves

Lambswool garments offer a balance of comfort and warmth, making them perfect for transitional weather.

5. Shetland Wool – Rugged, Durable, and Traditional

Shetland wool comes from Shetland sheep, a hardy breed native to the Shetland Islands of Scotland. This wool is known for its resilience and rustic texture, ideal for traditional knitwear like Fair Isle sweaters.

Key Features:

  • Coarser texture with natural durability

  • Excellent insulation in cold climates

  • Available in a variety of natural, earthy tones

  • Used for sweaters, hats, cardigans, and outerwear

Shetland wool is a favorite among lovers of classic British and Celtic knitwear for its authentic, timeless look and feel.

6. Mohair – Lustrous and Elegant

Mohair wool is derived from the Angora goat, not to be confused with Angora rabbits. It is recognized for its silky sheen and lightweight warmth, often used in luxury fashion and soft knitwear.

Key Features:

  • Shiny, silky, and smooth

  • Very warm yet breathable

  • Wrinkle-resistant and durable

  • Excellent for sweaters, suits, and soft accessories

Mohair is often blended with other fibers like wool or silk to enhance its drape and shine.

7. Angora Wool – Fluffy, Soft, and Extremely Warm

Angora wool is produced by Angora rabbits, and is one of the softest fibers available. Due to its delicate nature, it is often blended with other fibers to add strength while preserving its signature fluffiness.

Key Features:

  • Extremely warm—up to 7 times warmer than sheep’s wool

  • Lightweight and fluffy texture

  • Luxurious and elegant in appearance

  • Commonly used in high-end knitwear and accessories

Angora is a specialty wool with a high warmth-to-weight ratio, perfect for cold weather accessories and statement pieces.

8. Yak Wool – Rare, Sustainable, and Exceptionally Warm

Yak wool is sourced from the soft undercoat of yaks, large mammals native to the Himalayan plateau. It is often compared to cashmere for its softness and to merino for its breathability.

Key Features:

  • Warm, soft, and breathable

  • Eco-friendly and sustainable

  • Naturally insulating and wind-resistant

  • Suitable for sweaters, scarves, and base layers

As demand grows for eco-conscious textiles, yak wool is gaining popularity in ethical fashion circles and sustainable knitwear collections.

9. Virgin Wool – Fresh and Untreated

Virgin wool refers to wool that has been newly sheared from a sheep, as opposed to recycled or reclaimed wool. It is untouched by processing or previous use, making it soft, strong, and high quality.

Key Features:

  • Soft and pure

  • Stronger and more elastic than recycled wool

  • Common in coats, suits, and premium knitwear

  • Naturally wrinkle-resistant

Virgin wool is often used in high-end garments where texture and structure are important.

10. Organic Wool – Sustainable and Chemical-Free

Organic wool is sourced from sheep raised using certified organic farming practices. This includes no pesticides, synthetic hormones, or chemical processing. It appeals to environmentally conscious consumers seeking natural, low-impact materials.

Key Features:

  • Eco-friendly and biodegradable

  • Free from harmful chemicals or dyes

  • Safer for sensitive skin and allergies

  • Used in baby clothing, ethical fashion, and sustainable outerwear

Organic wool is part of the growing shift toward sustainable fashion, prioritizing both human health and environmental protection.

🧥 Final Thoughts: Choosing the Right Wool for Your Wardrobe

From the luxurious softness of cashmere to the rugged durability of Shetland wool, each type of wool brings something special to the world of clothing. When selecting wool garments, consider the intended use, climate, care requirements, and sustainability of the fiber.

If you're shopping for an Aran sweater, merino wool offers softness and warmth with everyday wearability. For more luxurious garments, cashmere or alpaca might suit your needs. If you value tradition and heritage, Shetland or lambswool could be ideal.

Whatever your preference, understanding the types of wool used in clothing empowers you to choose garments that combine function, fashion, and timeless craftsmanship.
