I bought my first Sweaty Bands recently. I am delighted that, as promised, they don't slip. I'm a bigger fan of the wider ones because they have even more of the magical fabric on the back that stays put. I have a big, punkin head and have never been able to keep hairbands to stay. So I'm excited I bought 4 of the cute glittery ones! This blue one, however, lasted me only one wear. Not because of the quality - because it is quite well made and I look forward to my OTHER ones lasting me for years. But this blue one was immediately absconded by my 19 year old daughter. I'm talking....quick.....it was gone. :) So, I guess I'll have to buy more. :)
