Looking for large Backpack for gym and work

Hello everyone,
I'm currently looking for a large backpack that can carry my gym and work equipment.
Gym: Sport shoes, gym clothing, small towel, large towel, Large Water bottle (1L), toiletry bag

Work: Macbook 15", Lunchbox, Ipad 11", charger, power bank, small Notebook and pen

and depending on the situation additional other small stuff.

Does anyone has a good recommendation for that, it has to be a backpack because I drive on my Motorcycle with it.
The cinomadist Gym & Training Backpack Pro 29L looks good, but I am afraid it is of bad quality because it has a really little presence but a lot of products in comparison to it.

Thanks for any recommendations!
