Why choose merino wool for hiking, summer and winter alike
merino wool is increasingly used for hiking. Indeed, the technical characteristics and benefits of merino wool garments are numerous. Discover why you should choose merino wool clothing for hiking in all seasons.

Impressive technical properties

Merino wool comes naturally from merino sheep, hence its name. Hardy and able to withstand changing temperatures, these sheep originate from Australia, Tasmania, New Zealand and Spain. In France, they are rarer, but flocks can still be found, notably along the GR69 La Routo.
Comparable to so-called classic wool, merino does not itch, which is why the textile industry uses it more and more. It is an excellent insulator that protects against both heat and cold. For skiing, it is often found in thermal base layers. This fibre is ultra-breathable, and stretches and compresses easily.
Furthermore, merino fibres have additional properties compared to classic wool. merino wool has the particularity of being finer and therefore lighter. And it offers other characteristics that make it the ideal ally for hikers. Let's explore these advantages.

The benefits of merino wool in the mountains
The main benefits of merino wool for hiking are:
- breathability and insulation
- odour resistance and quick drying
This is why merino wool garments are used for hiking, whether in winter or for a summer mountain hiking outfit.
Indeed, merino fibre offers incredible breathability that keeps you dry during exertion. It is also insulating, keeping you warm in winter and cool in summer. It is this balance between optimal insulation and moisture management that ensures comfort and hygiene for hikers. Technical mountain equipment in merino wool thus becomes the ultimate companion for summer outings (hiking, trek) or winter ones (ski touring, Nordic walking).
Finally, it offers a quick-drying capability — very handy on trips, treks and other outdoor activities! Thermal regulation is indeed optimal, which also helps prevent unpleasant odours. This impressive odour resistance of merino fibre garments means travellers can wear them for several days in a row without worry. Whether trekking or travelling, there is no longer any need to burden or weigh down your pack with a multitude of spare t-shirts.
Good for the planet
merino wool is also a benefit for the planet. It is natural in origin, durable, easy to care for and easy to recycle. Natural fibres are indeed biodegradable.
Furthermore, the production of merino wool garments requires less energy and less water. For example, producing 100 wool jumpers requires 70% less water than cotton.
Finally, most sheep farmers take the welfare of their animals and their broader environment seriously. For example, Australian producers are working to optimise soil health and increase biodiversity.
Outdoor manufacturers are looking for more affordable alternatives, in particular by offering garments made from merino wool and synthetic fibres — such as French brand Cimalp®. Its breathable merino wool t-shirts for hiking are made from CimaWool®. This fabric contains 47% merino wool and 53% polyester, exclusively developed by the Drôme-based SME. In addition, the dyeing process is organic and eco-friendly, and the fabric is certified Bluesign®, guaranteeing the preservation of natural resources and a reduced environmental impact.
