Having flown with two of those who are trialing it I can say that it looks nicer and will not fade. But it is a little too shiney for guys. Looks a bit outta place. Looked ok on female but it pulls on velcro (which we have a lot of at JQ) and is a bit too cool.
It is made of some stuff that extracts heat and odour from your body??? Something like that. And it is treated with some antimicrobial agent that will prevent us from stinking... Though it isn't the crew that stink - usually
How about cotton business shirts / blouses in charcoal or white? Nah - we couldn't possibly have a uniform that crew look good in and are proud to wear
