Rosti's POP jersey was developed by the Rosti Style research department in 2016. Long before the recent fashion shows. Rosti POP is a dual aesthetic project because it takes POP art back onto the road and makes it run fast. The jersey becomes a medium and tells us something about its wearer. Openly. Rosti POP is the long-sleeved Rosti jersey for winter. Rosti POP is in a brushed, thermic fabric; 94% Polyester and 6% Elastane. Full-length zipper, 3 appliqué back pockets and Lycra piping. The Raglan cut has been chosen for Rosti POP because of its ergonomic characteristics and because it embraces the movement of the shoulders.
