So this is pretty much a great bag. The material is strong and I've had my laptop in there (which weighs almost a literal ton). The straps aren't flimsy and they're quite long too, so the bag isn't sat high up in your armpit.
The one peeve I DID have when it arrived was the print on the bag. A bit of fabric had been caught in the print and when I pulled it off it removed the red ink, revealing a white worm of discoloration. It IS barely noticable, but my OCD eyes won't stop seeing it now it's there!
I've used this bag plenty already and I plan on using it a lot more, a good buy for any Slipknot/sturdy bag fan!
