How to change the font of the WordPress theme?

Hello Skandha, i was wondering if there is a way to change the font on the whole Catch Fullscreen Design to another Google font? As optimization is getting more and more relevant for Google the fonts need to be optimized too. So I've settled for Open Sans. Changing the font in the CSS-file of the theme works but theres a catch! I still have this call to the Google Fonts API in my website header: <link rel='stylesheet' id='catch-fullscreen-fonts-css' href='https://fonts.googleapis.com/css?family=Poppins:300,300i,400,400i,600,600i,700i,900i' type='text/css' media='all' /> That's still the default of "Poppins" which is slower to load. Is there a way to disable this call or change it over to the "Open Sans" font? Kind regards, Michael
