Winter sport equipment - 1st problem : Skiing masks don't protect the nose from cold at high altitude (really painful), burdening to transport and fragile because it's no really flexible.
2nd Problem : Sunglasses can break easily and don't protect from cold.
Concept : the two arches of the eyebrows are still, whereas the other part is supple, protecting from sun rays and the nose : good protection, compact, easy to transport, cumfortable, minimalist.
