Kirk Originals "Jay"...which is a one off unique model that Jason Kirk and I worked up together.  These glasses are solid, thick frames, and fit your head like a glove.  naturally you may need to have them adjusted a bit, but otherwise these are ready to go.  I have a bit of a big melon, so if you have a tiny head, these are not for you.  you'll never find these anywhere else.  these ooze Rock and Roll.  Hand made in London, UK.  Bid with confidence!
