For all we know, he does wear a cape.
Break away fasteners are a thing now. Line it with some Kevlar fibre and some good thermal insulation/fire resistance and you have an amazing utility device.
In public, it billows behind you, making you look dashing and heroic. When the shit hits the fan, instant bullet resistant cover for civilians. A way to shield them from the heat of a fire, or a small explosion. You could even use it offensively to tangle or deceive an opponent!
I’d settle for a cloak. A nice leather, or heavy woollen cloak would be amazing for being outside on cold evenings.
Unfortunately, they are still seen as dark and ‘edgy’. Moreso even than a trenchcoat. ☹️
Stop giving so many fucks about what other people think about your fashion. You do you, fam.
I remember early 2020, there was a small push to bring capes back, before something else took over every discussion. Something about blue jays or crows or something
