Abstract
A beverage container may include a container comprising a sidewall having an exterior surface and an interior surface. The container may include an inner thermally insulative coating applied to the inner surface. The inner thermally insulative coating may have a thickness of between 2 microns and 10 microns. The container may include an outer thermally insulative coating applied to at least a portion of the exterior surface. The outer thermally insulative coating may include a plurality of discrete protrusions about the at least a portion of the exterior surface. The plurality of discrete protrusions may be separated by one or more channels.
