Product concept & technology

Product Composition

Main fabric 100% Wool


We've tested the material in a climate-controlled room in order to determine its performance level. The results have proved the thermo-regulating properties of the wool. After exercise and heavy sweating, the wool is able to maintain body temperature while a synthetic material lowers the temperature again more quickly. The merino wool therefore reduces the unpleasant chilling or “freezing" effect.

Approved By

Our design team is based at the foot of Mont-Blanc, in Haute-Savoie (France). All year round, our designers create and develop products that are appealing, simple and technologically advanced. These are then ruthlessly tested in the field, because we believe that the only way to continuously improve our products is to test them under the real-life conditions that you will experience in use.
