This invention is an improved breather bag apparatus used with a sealed storage bin such as a silo allowing for expansion and contraction of the air within the sealed structure due to changes in the air temperature in the sealed storage bin. As a material with a high moisture content is normally being stored, the connector pipe between the improved breather bag structure is inclined back into the storage bin for any condensed fluid to flow back into the storage bin to keep the stored material moist. This improved breather bag apparatus is mountable on the sidewall of an existing silo within a protector shell member and having a bag member that is readily observable from adjacent the silo to ascertain whether such is operating properly and having a drain valve to release fluid from the bag member. The protector shell member is provided with a bottom wall with an access door to allow one entrance to the drain valve for operation thereof. Also, a special bag support assembly is mounted in the protector shell member and operates to hold the bag member in the proper shape.
