Yeah as an added bonus, you can keep a bunch of shit on you, versus the belt kit or ruck. The shoulder pockets are especially good for this purpose. Small E&E and medical kits can be carried here. The pass-through chest pockets are nice for maps, gloves, watch cap, etc. Front chest pockets are the office: notebook, pen, and flashlight on one side; compass, pace beads on the other. Waist pockets are good for over-mitts, windshirt or other thin layers, or even some snacks.
The shock cord cuffs are inspired by the old sewn in elastic cuffs.
I don't have the old "poacher" pockets on this smock, but also good for additional clothing layers that may be coming on n off as you travel.
