There was already info out there on the winter jerseys as another post talks about but that jersey was leaked two months ago...
From Uniwatch today:
Will the Warriors’ as-yet-unrevealed alternate uni look like this? Could be, according to a former Adidas employee. “That photo was taken in April, so tweaks may have been made,” says my source. “They were playing around with the idea of short-sleeve jerseys too.
my guess is jersey will be that script with the stripes and color of the shorts.
