I think it is a very good piece of kit and belongs in my bag, at the least, and perhaps it is also what is know as a "Baffle Bag".
I do wish it was lighter in colour, so if the camera is set up, it reflects warming light, but as is it'll do.
I think it would be even better if it had a matching material darkcloth, and a heavy vinyl window flat, that was removable, from under a camera wide permanent flap, for at 90 and 45 degrees, viewfinders prism viewfinder or a ground glass screen, could be used.
500CM/C Hasselblads have always been an outdoor camera, as well as a inside studio or location tools, which, again, is why I asked the question in the first place.
Leica/other copies of Leica's, 39mm mount cameras, have been used and submerged in sea and fresh waters, especially during WWII, as one wartime photographer observed, was a frequent issue to deal with, and the solution, no pun, was to simply put them in a bucket of fresh water, for rinsing the salt out, then dry them out overnight, presumably by a fan or heater with a fan, so they were ready to go the next day.
When making a new, expensive professional's camera in the following years, I would have though that would have been a priority, especially in light of the hours wildlife photographers sat in the weather, waiting for their quarry, especially birds and most especially, water foul.
Hasselblads 500 C/CM cameras, weak link is in the materials of the camera, and shuttered lenses, which include, it seems, steel parts that will rust, , ie. the shutters and self-timer.
That is a complication that deserved additional attention, IMO, that other than the weather jacket seen linked, above, that was never dealt with, in all the years of production.
With all the young shooters, or mature shooters that have/are come(ing) along, most of those I've see, online, are using these cameras and lenses, out of doors, in all kinds of weather.
No doubt about it, I will always view no minimum weather resistance is the #2 failure of Hasselblad Design, #1, as we all know, is the sync train of the lens, body linkage.
IMO.
