There is also such a thing as Argon 49 (7D) but I've not seen or read about it in actual use yet, although I haven't searched exhaustively for it.

But to me Argon is the perfect material for UQs, being quite splash and wind resistant.
Argon 49 is amazingly silky, impressively breathable, but still able to hold in down as it is calendared. Sacrifices some wind and water resistance, but it is so comfortable that it’s worth it to me!
