I honestly never thought about a soft case for mine. It’s durable enough that I can just strap it to my ruck and sometimes stow the bayo in a pocket if I’m worried about it. The mounting hardware is a bit of a pain though when the unit isn’t mounted. I’ve had the latches get messed up and spun around while transporting. The easy remedy for this is to use a piece of plastic pic rail to lock into the mount while not in use.
I realize this doesn’t answer your question, but…
PS I removed the display mount after a while. It made accessing the SD card problematic too many times for me. Also, when I used it with short barreled magnums, the blast from the brake hosed the cable connection port, making the display unit unserviceable and needing to be replaced.
