S.O. Tech released a video (below) that shows the final details of the ESP (Expanding SERE Pack). The production ESP in the video shows considerable differences from the original and the prototypes that have been shown along the way. The new version is slimmer, with just one external pocket (earlier prototypes showed two pockets). The body of the pack is made from color matched 200D Theta Fabric which keeps weight to a minimum and offers some water resistance. The pack’s adjustable straps are made from wide webbing and it has a grab handle for use when it is expanded.
