Wool: nature on your skin
Wool is one of the oldest and most versatile natural fibres ever used by humans. Technically, the term "wool" refers to any animal hair that can be spun into yarn and woven into fabric. The most commonly used wools come from animals such as goats (cashmere and mohair), sheep (Merino wool), rabbits (angora), camelids (camel, alpaca, and vicuña), and even bovines (yak). Among these, sheep’s wool has always been the most widespread, known and loved for its exceptional insulating properties and its ability to adapt to various climates and needs.
What makes wool so special? First of all, its natural structure. Each fibre is made of keratin, a protein that naturally retains heat, making wool an excellent thermal insulator. It is also highly breathable, capable of absorbing up to 30% of its weight in moisture without feeling wet, thus keeping your skin dry and comfortable.
Another unique feature of wool is its elasticity. The fibres bend and stretch without breaking, which makes wool garments durable and able to maintain their shape over time. It is also naturally odour- and stain-resistant, reducing the need for frequent washing and extending the life of each garment, making wool a more sustainable choice overall.
Merino wool: softness that redefines warmth
Merino wool is one of the finest and most appreciated fibres in the world, renowned for its incredible softness, versatility, and outstanding performance. It comes from Merino sheep, originally from Spain but now primarily raised in Australia and New Zealand. What sets Merino wool apart is the ultra-fine diameter of its fibres—often well below 20 microns, and in some cases as fine as 12 microns. This remarkable thinness makes Merino wool exceptionally soft and gentle against the skin.
What many call a “wool allergy” is usually a reaction to the coarse scales of lower-quality wool fibres (those with a diameter above 19 microns), which can cause itching. An extrafine Merino wool, like the 18-micron variety used by Oscalito, is so fine that it doesn't irritate the skin at all. Merino wool is often blended with other noble fibres, like silk, to further enhance its softness and luxurious feel.
One of Merino wool’s most unique qualities is its adaptability. Thanks to the structure of its fibres, it is naturally thermoregulating, creating a microclimate close to the skin. It retains heat when it’s cold and releases moisture when it’s warm, making it perfect for both winter garments and performance wear. Additionally, Merino wool is highly breathable and moisture-absorbing, keeping your skin fresh and comfortable even after a full day of wear.
Cashmere: a precious fibre, symbol of elegance
Cashmere is much more than just a fibre, it embodies luxury and sophistication. Sourced from the undercoat of Cashmere goats, native to the cold highlands of the Himalayas, this wool is famed for its unparalleled softness and lightness in the world of natural fabrics. Each goat produces only a small amount of cashmere each year, about 150 grams, making this fibre incredibly rare and valuable.

One of cashmere’s most appreciated qualities is its ability to provide exceptional warmth while remaining incredibly lightweight. This is due to the ultra-fine structure of its fibres, which trap body heat without adding bulk. Ideal for cold winter days, cashmere is also a remarkably versatile natural fibre, used to create sweaters, coats, scarves, and elegant accessories.
Alpaca wool: the treasure of the Andes
Alpaca wool is one of the most refined and fascinating natural fibres, originating from the highlands of the Andes, where alpacas have been bred for centuries in harmony with nature. This wool is renowned for its softness and silky sheen, making it irresistible to the touch and beautiful to the eye. Thanks to its unique structure, alpaca wool is warmer than sheep’s wool and incredibly lightweight, offering thermal insulation without weighing down the wearer.
One of its most distinctive features is the absence of lanolin, making it hypoallergenic and ideal for sensitive skin. Moreover, alpaca fibre is naturally durable, less prone to pilling and wear than other fibres, ensuring garments that retain their beauty and quality over time. This makes it perfect for sweaters, coats, and accessories that combine comfort and style.
Another remarkable trait of alpaca wool is its range of natural colours, from pure white to deep black, including endless shades of grey, brown, and beige. These natural tones reduce the need for chemical dyes, contributing to a more sustainable production process.

So similar, so different: discovering their common ground and unique traits
The different types of wool, traditional, Merino, cashmere, and alpaca, share some key characteristics: they are natural, renewable, biodegradable fibres, and all are valued for their warmth and comfort. However, they differ in softness, weight, and their ideal uses.
Traditional wool, sourced from sheep not specifically bred for fleece fineness, is warm and durable, perfect for heavy garments like coats and blankets. However, its thicker and coarser fibre can be less soft and occasionally irritating for sensitive skin.
Merino wool, on the other hand, stands out for its exceptional softness and fineness, making it gentle against the skin. It is breathable and versatile, ideal for lightweight sweaters or technical garments.
Alpaca wool, native to the South American highlands, is known for being warmer and lighter than sheep’s wool. It’s hypoallergenic due to the absence of lanolin and offers a beautiful range of natural colours. However, it’s less elastic than Merino or traditional wool.
Finally, cashmere is one of the most luxurious fibres: incredibly soft, light and warm, perfect for refined, elegant garments. However, it is more delicate, requires extra care, and has slightly lower resistance.
Not sure which one to choose? The best option depends on your priorities: go for durability with traditional wool, versatility with Merino, warmth with alpaca, and elegance with cashmere. Each fibre brings its own unique character, offering the perfect solution for different needs and lifestyles.
