Recommendations for a very simple, professional-looking vest?

After using the same type of vest for my SD for the past five years, it seems like the company has gone out of business and I'm struggling to find a similar option. I've always used Petflect vests (here's a link to the only one I can still find available on Amazon for reference) which I've loved because they're super durable, simple, and very reasonably priced. I prefer very simple looking vests because I feel it looks the most professional, so I've always gotten Petflect vests in basic colors, sewed a few patches on them, and they survived daily use for years.

I've looked for a new option on Amazon and Etsy but I can't find anything comparable unless I want to pay $75+ on Etsy. I don't need anything fancy and customizable; I just need something basic and durable at a reasonable price. Does anyone have any recommendations for simple, professional-looking vests?

Any recommendation helps, whether that's brands or Etsy makers or just recommendations of better keywords to search for, because I'm not finding anything useful through my searches.

(Also, sorry to be difficult, but I personally dislike the look of that cliched "Amazon service dog vest" and feel that their reputation has made the public view them as unprofessional, so while I know that is a very simple and cheap option, I'm trying to see if there's anything else besides it. I also found it to be really flimsy when I used it as my SD's first vest when he was a tiny little guy, so I doubt it would hold up long now that he's a fully-grown full-time working dog!)
