A towel might seem an unnecessary burden on most trips. After all, quality hotels provide them as standard, so packing one could easily become synonymous with slumming it. But one can come in handy after a dip in the sea on an unpeopled beach or freshening up in an airport terminal after a long flight. Besides, these towels are not bulky like their cotton counterparts. In fact, they are so compact that deciding to pack one is hardly a decision at all.
