That was all a song and dance by the inept APFA. Their own testing concluded it met Oeko Tex 100 standards as does the M&H and Lands End. There was nothing "toxic" in those pieces outside industry norms and what you are feeling in the current uniform pieces.

As for the "reactions", that vast majority were due to the wool content which is why alternatives were made. Out of 80,000 employees some are bound to have some issues. People are allergic to all sorts of things, that doesn't make them "toxic".

The TH-Alaska Airlines lawsuit was thrown out after being repeatedly debunked in all sorts of testing.
