This is one of the best gig bag around. Here is some info about the Mono Vertigo.
The Vertigo™ does not open like a traditional guitar case. Its design allows you to quickly unzip the case and pull your bass out from the top. This is enabled by a hidden diagonal hinge on the front panel of the case. Once unzipped, the case naturally opens out and to the right. No need to lay your guitar case down on the floor. A deep front pocket keeps your essentials at-hand
Fits all standard electric bass guitars including Fender, Ibanez, Fodera, Warwick, Tobias, Yamaha. Also fits some not-so-standard bass guitars.
Interested to trade it for Reunion Blue Continental gig bag http://www.monocase.com/mono-vertigo-bass.asp
