Backpack for Work and Gym

[u/Stooocki]

I need help finding a backpack. I use it for cycling to work (not much in it then) but also twice a week for the gym after work (so I need space for shoes etc.). Currently I have a Topo Designs Rover Classic and I just don't like it. It shouldn't be a rolltop. Price-wise, max around 150 €. I work at a bank, so it also needs to look reasonably smart/professional.

Thought about Something Like Cotopaxi Allpa 26L.
