This is the new Barcelona 11/12 away football shirt made by Nike, which is available here.
One of the other big changes for the new season is the colour of the away strip, which unlike the last six years, will not be a bright, vivid colour. The shirt, shorts and socks will be completely black. On the back there is a small embossed inscription in black and dark grey silicone that represents the same design of the Catalan flag, the ‘Senyera’.
The socks, like the first strip, include a mesh in the shape of three rings and printed with the letters FCB in the yellow of the Catalan flag on the calf.
