A Breather is a piece of headwear worn by Kryptonians. It is worn when a Kryptonian enters a new world's atmosphere, and designed to protect a Kryptonian or other life forms, such as humans, from hazardous atmospheres, while also blocking out the environmental factors that lead to Kryptonians' sensory overload (if the new planet is in the system of a yellow G-type main-sequence star).
