well i have tryed a few. The pertex ones are the smallest and are not very good at getting you compeltely dry. I also have a cheap kind of thin micro fiber, which is a bit between like a pertex one and a thicker pack towel. It doesnt get you completely dry either. Both dry quickly.

The coughlans sure feels like a large house hold cleaning cloth. Takes forever to dry.
I also have a thicker packtowel, which is great in absorbing moist, but also takes forever to dry.

Have not tryed any expensive pack towel.
