Offical Scuderia Ferrari F1 Team Wear - NOT a knock off - Bought new at COTA last year, and just found out that my better half also bought one for me as a gift - so don't need 2 - even though Ferrari is leading this year.  MINT flawless condition - never worn. 100% cotton w/ extra button sewn to info tag with 100% cotton label.  Proper US size for US Men's X-L - not a Goofy EU X-L that is 2 sizes too small for US Men X-L's.  Sewn in green & white strip around collar and shirt sleeves - and picture of tean name is on the back below collar.
