as far as i know,there are two types of authentics for adidas - Formotion and Techfit
Climacool jerseys are pretty much replica versions of the ones players wear on the field...
for the authentics,they're cut slimmer than the Climacool jerseys...
and Techfit ones has the Powerweb strips at the back of the jersey:
Ibrahimovic also wears them for Milan...
unlike the authentics,Climacool jerseys has the hologram on the lower front and the 3-stripes on the sleeves and also the adidas logo are not made from those plastic transfer material...
