Where can I get the black/gray striped cardigan Daniel Tosh wears?

There's a very repetitive picture of Daniel Tosh wearing a black and gray striped cardigan and I can't seem to find it anywhere. It's the one he's wearing under the "send us stuff" caption on this page http://www.comedycentral.com/tosh.0/2009/05/13/send-us-stuff/. Any help is appreciated!
