Duffle Sac Timeline
The first iteration of the Duffle Sac was designed with seams on the sides where the buckles attached, with a flat bottom and no edge binding (some early examples do exist with piping in between the base seam). No internal pocket. Produced with either a metal tag or "cartouche" stamp.

The next iteration of the Duffle Sac saw a construction change that moved the side seams to the center. You can see in this example here that there is now binding along the bottom edge. An internal pocket was also added. Produced with either a "cartouche" stamp or NYC creed.

Moving back to the original look, this last iteration of the Duffle Sac was the longest lasting. This version features side seams, binding along the base, and an internal pocket. Produced with NYC creed.
