The bag seems very durable and rugged - it almost stands up on its own, which is great, because it feels weird trying to fold it.
Things it can fit: 2 electric guitars, 2 cables to connect the guitars to a pedal and then an amp, 2 spare cables because the bass player wont buy any, one xlr cable for direct out, tremolo bar, capo, toolkit, laptop, charger, notebook, pen, a light snack and a beer (only one though).
Things it can't fit: my Zoom G5 multieffects pedal. It's 2cm too long. Although if I could fit the pedal, I couldn't fit the laptop.
If you're ever stranded in the wilderness with this bag and are willing to sacrifice one of your guitars, this bag can probably keep your feet warm when sleeping (don't try this though).
The biggest issue with the bag are the straps, which are too close to each other at the top. The straps dig into the back of your neck hard. You'd think the weight would also be a downside, but it's really not that heavy.
