I rather suspect (although the profoundly unhelpful flash style website they've got is stopping checking for sure) that it got canned and replaced with something slightly different a bit back. Brands do that an awful lot nowadays, sometimes with profoundly annoying speed.
If they are still making it then they've probably stopped it for winter so likely out of luck.
It was very good for its time, perhaps less so nowadays as weights have come down and stuff, and can get 3 layer fabric coats for the same sort of weight/cost.
Tons of recent threads cf such things, as in here, here, or here,
