I've been cleaning house of many items purchased but never used. Here is my World Tour double gig bag. There has never been a bass to see the inside of this. It's pretty darn heavy duty for the price range with plenty of storage and carry options.
I'm at work, so no actual pics, but so sayeth ZZ Sounds:
