Man the construction worker in me just sees a muscle shirt outline, a tin of chew, a key ring, set of steel toes and a daughter’s bracelet. But I guess any image can be intentionally made misleading eh?
Are undershirts usually lumpy? Undershirts are lightweight enough to not really affect the overshirt. They're also smooth other than wrinkles—there is clearly some padding being offered by whatever is under that shirt.
You are describing the loop of plastic audio wire poking out of his shirt as a keyring there. You can look up higher res copies of this image. Duckduckgo had two different, higher-resolutiot copies right at the top of the page of this guy. It's supposed to be hard to spot them, otherwise they wouldn't exactly be doing a good job, yeah? Also, this picture specifically is being shown because the guy was confirmed to be an undercover cop. It was during the George Floyd protests.
If you zoom in (the potato quality image) there is absolutely the outline of a vest under the shirt. The printing on the back pocket is not round like a tin of chew. The rest I couldn’t say for sure, boots, bracelet, etc. but the vest and cuffs look dead on.
Start by not talking to cops, even if they're just potential cops.
If you came with friends to an action then stick to talking with just your friends until you have more experience. If no friends then it's better to go to events outside of protests to talk to folk.

I mean, I'm aware that's considered good advice in general. FWIW though I'm assuming this is with 20+ protesters standing in easy earshot, not a private 1:1 conversation. Maybe there are better questions, or someone else should ask? Or is it better to ignore the potential cop? I feel like other protesters would want to be aware who is hiding among them.
Until you're experienced in the situation it's best to just ignore and keep distance. You can run the risk of fed-jacketing (calling someone a cop/fed without solid evidence). Observe others and learn from the experienced folk in your particular groups as to how this should be handled because it does vary from scene to scene.
This is also generally true for media/journalists. If you don't have media training, don't make a fool of yourself and by extension everyone else.
When you're starting out, just get the feel for things and learn how to keep yourself and your friends safe. Learn how to calculate risk and threat model. Learn how to keep communication and coordination with friends in the chaotic environment.
You must not have seen very many tins of chew or key rings during your time as a "construction worker" then. That's not even close. Me thinks you doth protest a bit too much. Your comment honestly reinforces this image even more.
If any actual patriots are reading this and see something like what's in this image at a protest, be very skeptical of that person. Protect yourself and don't let obvious agents tell you to brush it off as something else.
You're not wrong. Protestors can face retaliation which causes paranoia and is an obstacle in growing organizing efforts. There are some arguments in the comments about what the specific items are, but there are more explanations that fit their defenses. For example, it could really be a vest under the shirt, but maybe it's a disabled person's cooling vest and not a bulletproof vest. I urge yall to still be cautious of strangers, including waryness of people who look like they can be the correct demo for cops, without also running off people we don't really know anything about with our bad attitudes.
