Yeah ... just what you should encourage people to wear on the 4th of July. A highly flammable material. At the least, it would melt from a stray spark. Or they could wind up with 3rd degree burns if the material sticks to their skin while it melts/burns.
Nope ... it's still highly flammable, every other day.
It's also risking collapse from heat exhaustion, since the material doesn't "breathe". This has been pointed out to you numerous times, yet you insist on trying to get people to risk their lives.
