If you’re ever in Sydney Australia check out Maplestore. They have 2 locations Newtown and Balmain. I believe there’s flagship stores in NYC and Montreal too. Good luck with your search!

I’m sitting at work wearing my tan canvas Weird Guys right now. The logo isn’t noticeable as it’s embossed on to the leather patch. Anyone spending that much time looking at it are probably due a trip to HR. It takes a bit of time to understand the cut I was fortunate to be able to try them on in store. Can’t recommend them enough.

Naked and Famous. They have a range of cuts so you aren’t stuck with a work pant cut. Some styles they do a Selvedge Duck Canvas which is very hard wearing.

I rock the Ironsight from this collection in a business setting, doesn’t look out of place. was reasonable price but limited run

Try over at r/backpacks too because there’s lots of options these are just my favorites
