How do I change the header menu font?

I currently have the font on this demo: http://themenectar.com/demo/salient/

I want the font from this demo: http://themenectar.com/demo/salient-frostwave

This is my website: http://www.greensocials.com

I went over to typography and there's a lot of fonts available for this but they don't have a preview and I don't have time to test all of them
