The world needs a new source of energy, an unspillable source.

What is it that the character “Nikola Tesla” on SyFy’s “Sanctuary” wears around his neck?

The character, played by Jonathon Young, wears something particularly dashing around his neck (an ascot, maybe?) and I want one. If there are any special notes about it, those would also be helpful (i.e. cravats are tied in many ways; is his a particular knot, perhaps?).
