These are thinner than the original buff, just a smidge.  which makes portability better (a *little* smaller in your pocket)
They are also not as tight as the original buff (just a smidge), which makes it more comfortable for me as a headband (I *have* to have a headband while hiking & traveling ... my forehead sweats *a lot* ... I didn't think my head was particularly large, but the original Buff is really too tight for me)
And really good for travel to cover neck (sun), headband (sweat), and for mosques (headdress for women) and synagogues (headdress for men)
They are 10% of the cost of the original buff.
I just wish there were more patterns available at this price, as I already bought 4 sets! (ok, 1 set was for my husband ;-)
