doubleskinned
Doubleskinned refers to a condition or characteristic where an object or organism possesses two distinct layers or skins. This can manifest in various contexts, from biological organisms to manufactured materials. In biology, a doubleskinned organism might have an outer protective layer and an inner, perhaps more sensitive or specialized, layer. For example, some marine invertebrates exhibit a double-layered body wall that serves multiple functions.
In material science and engineering, the term doubleskinned can describe structures built with two parallel layers
