I am actually surprised how comfortable this is to wear. I am heavier and this stays in place small and I don't even realize it is on. I always carried my phone and cc card in my back pockets, I tried a skinny running belt ended up hating it, it would ride up my back. I saw this and thought I would try it. It's the size of my phone not extra big. I am very happy. My 8year old wants one too. It fits her great as well
