GOOD BACKPACK COMPANY!?!?

so i need a backpack for school and trips and stuff. i am a 13 almost 14 year old girl and i want one that would be defined as "cool" i guess you could say... like something burton or roxy or hurley or something. i like most colours (not plain pink... only pink if mixed with other colours) and gray is good too. also preferably under $50 if possible. links are appreciated !
