interestingly, china propagandized this peacetime soldier who died in an accident, lei fang, into this model citizen of kindness and selflessness, and thus the chinese call the hat the “lei feng hat” after propaganda depictions. whether that (and the fact that northeasterners usually wear the hat regardless of politics to combat cold) means it has shed communist symbolism is up to you

I believe Anarchist Batman from the Redsun Supperman comic used one.
