I carry a
Buff as a part of my EDC and it shares at least some of the flexibility attributed to the shemagh in that article.
Being more compact, its easy to carry in a back pocket and I've used it as a neck gaiter for the colder days of the motorcycle season, as a sleep mask when camping in the summer, as a face mask during cold winter days and as a bandana on days when I didn't have any other head gear. I find it to be a very flexible and useful piece of gear.
