Aquis Microfiber Body Towel
This is the best towel I've found.
It costs marginally more than a normal, high-quality towel, and in my experience is several times more effective at drying your body. It's also much thinner than a normal towel and dries much more quickly, so it's great for packing (not to mention it feels incredible).
