I was a bit worried that these would be of too low quality to last very long. So far, I've washed all of these at least a couple dozen times, and have worn them while at the gym, while hiking, as luggage markers, to wipe up spills in a jam, and various other situations. They're not thick, but they always do the job.

They also look pretty cool too, in a I'm-secretly-still-twelve-inside kind of way. Would buy again, maybe in a different pattern.
