Abstract

L'invention fournit un vêtement spécial refroidissement qui permet de favoriser le refroidissement du corps par une configuration simple. Ce vêtement spécial refroidissement est équipé : d'un corps principal de vêtement (10) qui est fabriqué à l'aide d'un matériau en feuille spécifique possédant une perméabilité à l'humidité ; et d'un moyen d'adhérence (20) élastique qui est posé depuis un côté externe sur une zone spécifique du corps principal de vêtement (10) et qui fait adhérer ladite zone spécifique sur le corps ou sur les sous-vêtements. La transpiration provenant du corps pénètre côté face externe du corps principal de vêtement (10), et s'évapore au niveau de sa face externe, en raison du gradient d'humidité généré entre la face interne et la face externe du corps principal de vêtement (10).
