I believe that both Context and Farinelli’s have sold all of their preorders for the special Filson x Apolis Activism briefcase, but it looks like you might still have a chance to get one straight from the source: http://www.apolisactivism.com/?event=startPreorder

Context also has some great interviews on their site concerning the work and ideas behind the bag: http://www.contextclothing.com/eye_to_eye.php

Update 2: For the Canadians, Roden Gray is taking preorders as well.
