Wool

Extra fine merino wool yarn 19.3µm

Compared to other types of wool, merino wool is always fine and soft, generally less than 24 micron (μm) in diameter. Yet, it is graded by its fineness to produce yarn. The finer the wool used to produce the yarn is, the softer it will be on the skin. Extra fine merino wool can be worn directly on the skin even on the most sensible parts. It is very pleasant.

knit type interlock

Interlock knit is a double-knit pattern that makes it thicker and more durable than other knit fabrics. It is a reversible, smooth and firm texture, resistant to wear and tear and comfortable against the skin. It has a good amount of stretch in both directions (horizontal and vertical), providing comfort and flexibility. Interlock knit a popular choice for high-quality, long-lasting clothing items.

Midweight merino wool knit 250gsm

This is an indicator of the merino wool fabric thickness. GSM stands for grams per square meter. Midweight is the most versatile thickness. It is warm in cold weather as an underlayer and extremely pleasent in warm weather as a single layer.

Mulesing-free

Mulesing is a practice in which skin is removed from the rear of the Merino sheep in order to prevent parasitic infections from flies. It is efficient but controversial because of its cruelty. Alternatives exist through selection of resistant animals with lower skin wrinkling and through the use of non-surgical alternatives. Mulesing-free guarantees that wool is sourced from non-mulesed merino sheep.

Oeko-Tex Standard 100

Standard 100 certification guarantees that the certified item has been tested against harmful substances and that it is therefore harmless for human health. Tests are conducted by independent institutes based on criteria of Standard 100. Absence of numerous regulated and non-regulated substances, which may be harmful to human health are verified. Limit values for the STANDARD 100 often go beyond national and international requirements.
