This is the Bolt Backpack by Waterfield Designs. This special model has been retires from their website and is hard to find if you like canvas Backpacks that have an Indiana Jones vibe.

I've only used this backpack a handful of times and it's still in good condition no visible damage.

I'm including a description of the backpack I found online for reference below:
