Our design team is based at the foot of the Mont-Blanc, in Haute-Savoie (France). . These are then ruthlessly tested in the field, as we remain convinced that only through rigorous testing under real world conditions, like the ones you will be using them in, can we continue to provide you with better products than ever.
We carry out the following 2 types of thermal tests: - either a test on the material used in our fleeces. - or a test on a thermal mannequin in a thermal room. In this room, we reproduce the temperature, wind (5 km/h) and humidity conditions that you would experience on a mountain when walking at 5 km/h. These tests are used to validate the choices we make in terms of design. And we make adjustments to the thermal insulation in the areas where it is most needed.
