Its not often the names Neil Barrett is mentioned in these corners, but it seems his name has been attached to some impressive things of late. This bag produced by the formidable Porter, which celebrates the Neil Barrett  store designed by Zaha Hadid opening in Aoyama during September which we had a look at here. The W Boston Bag features very little in terms of detail but what impresses is the leather additions to the nylon piece and white and black handles.
