Abstract

La présente invention concerne un couvre-chef comprenant un masque antibuée, comprenant : une partie cylindrique (2) composée d'un matériau élastique ; et un masque antibuée (5) accouplé à une partie de respiration de la partie cylindrique (2). De plus, la présente invention concerne un masque antibuée destiné à empêcher la buée, dans lequel une valve (50) dotée d'un filtre est raccordée au masque (100), et les corps étrangers dans l'air sont filtrés lors de la respiration à l'aide de la valve comprenant le filtre. En outre, l'air exhalé de la bouche et du nez au cours de la respiration ne peut pas monter près de la surface du visage, empêchant ainsi l'apparition de buée sur la surface des lunettes ou des lunettes de protection. Par conséquent, il est possible de faire de l'exercice ou de marcher de manière sûre et agréable tout en portant un masque car une bonne visibilité est maintenue.
