Does anyone know what these hats are called?

They’re like beanies.. (for girls) but worn further back on the head.. They’re like the one in this pic, the girl on the left (sorry for the weirdness of the pic, its all i could find) http://photos-e.ak.fbcdn.net/photos-ak-sf2p/v198/46/11/504554636/n504554636_322956_4748.jpg

They’re like that but worn a little further back, and they’re smaller. Anyone know?!?!
