| MERINO WOOL | The comfort and performance of merino sheep wool are simply exceptional. It is soft and very flexible. An excellent thermal insulator, it ideally regulates body temperature both in winter and summer. It can absorb one third of its weight in the form of water vapour, its heat release prevents the sensation of cooling, and even when wet the garment remains warm... Wool fibres are naturally resistant to mechanical wear, get dirty very little, and are antibacterial, significantly reducing unpleasant odours as well as the need for washing. Like all natural materials, merino wool is biodegradable. |
| RESPONSIBLE WOOL STANDARD | RWS is a voluntary global standard that aims at the welfare of sheep and respect for pastures. It ensures that farm practices have been verified, so that brands have a clear solution allowing them to confidently make claims about the origin of the wool. |
| OEKO-TEX® | Oeko-Tex® is a testing, auditing, and certification system intended for environmentally friendly operations throughout the textile production chain. It includes all relevant operational areas (management, production technologies, resource use, quality assurance, safety precautions, social conditions, etc.) in its sustainability review. To be certified compliant with the Oeko-Tex® standard, companies must meet defined criteria relating to their environmentally friendly production processes and also be socially acceptable at all stages of production. |
