Spec me up a Man Bag (For the tech not the blusher)

[lego]

I doing a fair bit more travelling for work at the moment which results in more time on trains, in hotels and general waiting. Though I do tend to take a larger bag with me when staying overnight, I'm looking for a smaller bag for the day trips.

I will generally take my Nintendo switch, my surface pro, a power pack and I've recently been taking my camera (Nikon 3400D so not the biggest SLR out there)

I was hoping to get a messenger bag, but I don't think the camera will help with that decision. Ideally, I would want something that's secure. Just wondered if anyone has something that holds similar items?

A budget would help.

Billingham are brilliant for messenger/camera bags.

£150 would be my upper limit, though I would prefer t spend a lot less
