Much more than just a sweater

To find the wool sweater that will follow you season after season, it is essential to take into account several criteria:

- the origin of the raw material
- its composition
- manufacturing methods. 

No more clichés about grandma's wool sweater! Choose a merino wool sweater that offers you the best natural properties and optimal quality for all your activities, whether in the mountains or in the city.

Wool as a raw material 

There are different types of wool depending on the animal. For sheep the main ones are Merino and Shetland. There are also goat hair such as Mohair and Kashmir. But there are also llama hair like Alpaca, or rabbit hair like Angora. Henjl chooses to work exclusively with merino wool, which offers the best compromise between durability and performance.

Choosing a 100% merino sweater guarantees warmth and natural softness. As the primary function of a sweater is to provide warmth, it is essential to choose a quality raw material. Contrary to synthetic materials, a sweater exclusively made of wool keeps the primary property of the wool fiber: thermal inertia. Wool naturally stores air while absorbing moisture, which creates natural thermal insulation. The warmest wools are the wools that store the most air.

Merino ?

A woollen fleece is made from sheep's hair, a biodegradable, natural and annually renewable material. Not all wool fleeces are of the same quality. The breed, the origin of the sheep and the weather are important factors that make all the difference in the quality of the wool.

The merino sheep is one of the oldest breeds of sheep but also and above all one of the most robust. The merino sheep lives in a climate that is as hot in summer as it is cold in winter. And it is thanks to its ultra-light and breathable fleece that it can live in such a climate. Wool fibre is a smart material and will adapt to the seasons and temperatures. Insulating from the cold in winter but also from the heat in summer, wool is thermo-regulating. Indeed, sheep do not shed their hair during the different seasons because wool naturally regulates the body by evacuating excess heat.

Merino wool, cashmere from the sheep

A fleece is made of several sizes of wool fibres but mainly of coarse wool fibres (above 22 microns). That's why some wool sweaters are itchy! For example, a Shetland sheep's wool is around 30 microns. The wool fibres are then very thick and stiff, like little needles that rub against the skin and cause itching.

Below 20 microns, merino wool is considered an extra-fine fibre and does not sting. Just like cashmere or alpaca, some of our products are made from a "super-soft" merino yarn, 16.5 microns, almost identical to the fineness and softness of cashmere to allow you to wear your merino wool sweater right next to the skin. It is important to know that the finest wools are the most expensive wools.

100% wool VS synthetic

Thanks to its natural properties, wool is self-sufficient. This is why a large part of our clothing is made of 100% merino wool. However, in order to guarantee a high quality product for the practice of mountain sports, the choice of material mix was inevitable. However, not all blends are the same! Indeed, choosing wool as raw material for our sweaters to integrate a synthetic material of lower quality would not have been relevant. That's why the Henjl ski wool sweater has a mix of materials, all chosen for their environmental as well as ethical qualities.

The origin of the raw material is not everything! In order to retain all the natural properties of merino wool, it is essential to work with employees whose know-how is exemplary.

  • Our supplier Schoeller: The spinning process is a curative step. It consists of combing the wool fibres more and more finely and in parallel to twist each fibre with each other until an extra fine, smooth and long woollen yarn is obtained.
  • Our factories: INARBEL, REDA, RUIZ, GARLITA... Then comes the moment of knitting in our French or European factories which bring all their expertise for different knitting according to the product and its final use.
