I have a flightcase for my Telecaster but moving around with it between home, rehearsals and gigs was getting very uncomfortable. I own a Continental Voyager (RB's flagship gigbag) for my 5-string bass and I love it so I was curious about this RBX series...
It is perfect!! The RBX-E1 gigbag is very lightweight but feels sturdy like the CV! Although it doesn't have some of the CV's features (like the ability to "hide" the shoulder straps) it is actually more practical and comfortable to use, especially when it comes to the weight.
The front pocket, like in the CV, is brilliantly designed as it allows me to neatly store my cable, strings, pick-tin, multi-tool, cable-cutter, sheet music, laptop, etc.
You can even slide the guitar in and out of the gigbag just by unzipping both sides halfway: no need to lay the gigbag on the ground!
I've yet to find a single negative thing to say about this product. Reunion Blues know what they're doing!
