Hiking towels differ from regular towels by material.
The downside to most hiking towels is they are slightly less water-absorbent than cotton towels and can feel synthetic to the touch.
The use of microfibre means the towels are light weight, pack small and dry quickly.
We used the towels many times each day, got them wet, covered in sand, rolled them up, hung them out to dry, sat on them, stood on them, did everything you would practically think to do with a towel, and they finished the journey looking and smelling as great as they did when I first pulled them out of the postage pack.
