That's a nice sized bag. Over in the states I've used my wife's DSLR bag. It's a bit oversized for it, but I've used the extra space to toss in different cables, a portable battery, controller and other junk. The padding is modular so you can fit things at your preference.
It's on Amazon as well. Not sure why the orange interior version is currently $10 more expensive. It goes for $20-$24 regularly. There's also the medium sized bag, which might be better suited for just the GearVr.
I've been extremely impressed with this bag: https://www.amazon.com/gp/product/B00CF5OHZ2
Fits my GX85 with a lens on it, 2 extra lenses, full size flash and wireless links, misc filters and cables, and an extra wrist strap, with room left over.
The smaller size might be good if you just want to carry the camera and a lens.
