Last i heard Matt had to step away from the business for a bit to deal with some personal things. You may also want to try to get in contact with Topstitch if you cant find him elsewhere, i believe that is his father's company, they may know how to contact him.
Hopefully everything is ok with Matt, he does great work and is a nice guy to deal with. Hopefully he gets you straightened out and comes back to us to provide great gear. I have some of his packs as well as a bunch of PBMafia gear and it is all top quality gear i would not trade for anything else.
