PURPOSE: A protection wear having a mist preventing device is provided to prevent protecting glasses and an inner side of a protecting mask from misting due to vapor or steam, thereby increasing the safety and convenience in dispensing agricultural chemicals. CONSTITUTION: The protection wear(10) comprises: a body portion(11) which wraps the torso of a user; a hat portion(12) which wraps the head of the user, and includes protecting glasses(21) made of a hard, transparent plastic material, and a protecting mask(23); and a mist preventing device(30) installed on the protecting mask(23) and having a casing, an air communicating hole having a grid-type stopper, and a rubber valve. When the user exhales, hot air pushes the rubber valve blocking the air communication hole to be exhausted outside the protection mask(23), thereby preventing mist. When the user inhales, the grid-type stopper prevents the rubber valve from being pulled inward and blocks the communicating hole, thereby protecting the user from the agricultural chemicals.
