@ricitosdeplata : Sorry I can't help, I don't think these do unless stated. But since they are authentic Buffs, surely you could get the same ones off their website? Or if you don't find them, contact Customer Services and ask?
I use Buffs for just about everything - my merino one goes on in the morning when it's cool (I tend to walk in September or March/April) until I get warm, or I can use it as a hat or just pull it up high or down low over my face against the cold. My normal one is a headband, hair dryer (I have long hair and pull it over my wet hair to stop it dripping everywhere), neck cooler when dipped in cold water, neck warmer when it's windy, I have an Infinity one that can do duty as a colourful scarf, en route hand towel, shield my head and neck from the sun (I can't stand hats) etc.
I'm not telling anyone how many I've got but you never know when you lose one so it's only sensible to have a few spare ... surely?
