Abstract
A sun mask towel is provided, made from a planar section of fabric for blocking or reflecting the ultraviolet rays of the sun. By including eye, nose, and mouth slits, the sun mask towel allows users see, speak, and breathe easily. The sun mask towel effectively shields a user's face, head, neck, and in one embodiment, a user's entire body from the harmful rays of the sun. Further, the sun mask towel is easy to use and easy to carry.
Novelty This idea has definitely existed before: construction workers that work under the sun and don't wanna get sunburnt; bank robbers while doing their job (although their fear of getting sunburnt is probably not the primary reason of wearing such a thing), etc.
Non-obviousness
A balance between creating a monopoly and encouraging innovation you say, that is why non-obviousness is one of the requirements for patentability. This thing pretty much can be made by anyone with a piece of cloth and a pair of scissors. Very obvious.
Usefulness
If you really wear it, ya.
Enablement
You don't need to imagine an arbitrary average person in the industry. Even your neighbor's 3-year-old can make it.
