I sort of created a system where the tiny bag in the front will contain my personal stuff like phone charger, water bottle, wallet, earphones, etc.

The first bag in the back contains the tech stuff like laptop, audio interface, and microphones (if any), and the larger bag contains the heavy lifting stuff like the cables, smaller table mic stands I can fit inside it, duct tape, scissors, AC/DC adapters and so on.

Last time I did 20km each way on it, and although I got home pretty tired, it also felt super rewarding as well.
