It takes a few weeks of use and it loosens up a ton.
Yes, that's true.
To everyone getting a new carry case for the first time, I would like to offer a "tip" about wear and tear:
When you unzip it to remove the Empeg, always unzip it
all the way. It's tempting to only unzip it as far as is necessary to get the Empeg in and out. But I managed to break the zipper on my Mark1 case by doing that. The zipper gets extra wear and tear at the corners and wherever you bend it to open the case. If you unzip it all the way, then the wear and tear happens at the reinforced spot at the bottom of the zipper's travel.
