Microfiber Towel:  You would not believe all the uses of this simple travel item has.  The Professor clips it on to a backpack and uses it to wipe his glasses clean, wipe down surfaces, use it as a mini-towel, and when in need, as a washcloth.  A simple item with so many uses. The one we like does the job and is cheap.  Buy it.
