Looking for a not horrible version of this bag

[OrrAppleCheeks]

I have a really cheap across the body/sling backpack that I use for walking - this one from Mountain Warehouse

https://www.mountainwarehouse.com/p/042451/mw/classic-8l-sling-bag/

It’s really practical and comfortable, but horrible. I’d like something in a similar style, lightweight and waterproof/water-resistant, but that I can also use with non-walking clothes and not look like I’m about to take the dog for a muddy walk. I like Rains but they don’t seem to have anything suitable. Any ideas please?

My favourite is the Oliver Bonas, but not so practical for walking/rain.
