The stripes are not big, fat stripes, "Fairly wide" may have given the wrong impression. They of average width, about as thick as the 2013 Hertha kit as described before, maybe slightly wider.
The teaser picture does not reveal the whole arm is blue, and I am just saying what i saw. If you don't believe me that's fine, i am just describing it best i can
From that, I cannot know the entire arm is blue, just a part of it. I have seen it, and the arm is blue from the shoulder to before the white hoops. you don't have to believe me, I am just saying what i saw
I have seen, but it is fairly diificult to give a good image of the kit without it being generic. Apart from arm hoops-I couldn't have known that from the teaser picture.
I cannot provide my source but 100% genuine. It has a round collar, blue arms with thick hoops at the end of the arms. The stripes are fairly wide, and I don't know if it was just me but seemed a fairly dark(er) blue.
