Did you know ? The ptarmigan - our totem animal - changes its plumage depending on the seasons. It turns white in winter to escape predators and increases the fluffiness of its feathers to avoid cold spells.
The GRAND TETRAS jacket is inspired by this: it plays the role of the last layer, the one that protects from wind and rain, without sacrificing breathability... And therefore comfort.
To enjoy your favorite activity whatever the weather, here's the basics: layers.
The first layer, called the internal layer, must be breathable, to guide perspiration towards the outside of the garment.
The intermediate layer is insulating, it helps retain heat.
The outer layer protects against bad weather: waterproof, breathable, windproof. It is to this last category that the GRAND TETRAS belongs.
By building your outfit based on this system, you gain comfort and versatility. During exercise, you can remove the intermediate layer and then put it back on. In short, multi-layering is the basis.
