BOCOMAL FR Shirts Flame Resistant 100% C NFPA2112 7.5oz Men's Fire Retardant Welding Shirt

Saw a review that says the shirt had no "fr" indication but on the pictures it clearly shows the "fr cat2" rating.... So wich is it?

What is the recommended washing method?

Does the shirts come with the orange logo on them or is that just for a visual for Amazon

Is this treated with chemicals?
