By Affordable I mean under $300, better under $200. So I work in tech field as engineer but I do pay attention to my outfit. Most people wear T-shirt, casual button-down and jeans here, and carry backpacks. I'm on the dressier end, with casual bomber jacket + casual/dress shirt + jeans / chino + sneaker / monk straps. I need a bag to carry my 15'' macbook pro to office, at most along with a iPad mini, so definitely prefer to be on slim side like 3'' - 4'' inch depth. Right now I'm carrying a Everlane tote bag: https://www.everlane.com/products/mens-twill-tote-reverse-denim-black-leather which I like the material, styling and color, which also seems suitable in our casual work environment. The only complain is that it's a bit feminine. So I'm looking for a non-leather (since that would be a bit too dressy) briefcase, but I also don't like nylon. This knomo bag really caught my eye, https://www.knomobags.com/usa/princeton-laptop-briefcase-grey.html I really like the styling, the size, and the casual look. But it doesn't seem to be a SF-approved brand, do you have any recommendations for my need?
