I adore these headbands. They look great with many hairstyles. I wear them most often when I work out. I wear them on long runs, during Cross Fit, and yoga. And unlike other headbands I've tried in the past, I don't get a headache. If I position them in the right spot on my head, they do stay put (if I wear them too far back from my hairline, they tend to slip). I wore one for a 10 mile run yesterday and it barely moved! (I have straight hair and most hair accessories tend to slip off after a while.) The only thing I don't like is that the hair ties tend to stretch out after 1 use, but I guess given the material, that's to be expected.
