Lightyears  Suggested by pilaster 

In the css we find
@font-face{font-family:"NBold"; src:url('Neutra-Bold.eot'); src:local('NBold'), url('Neutra-Bold.ttf');}
@font-face{font-family:"NBook"; src:url('Neutra-Book.eot'); src:local('NBook'), url('Neutra-Book.ttf');}
@font-face{font-family:"NDemi"; src:url('Neutra-Demi.eot'); src:local('NDemi'), url('Neutra-Demi.ttf');}
@font-face{font-family:"NLight"; src:url('Neutra-Light.eot'); src:local('NLight'), url('Neutra-Light.ttf');}

Neutra is the body text.

Not an ID, but shares some very similar glyphs…
