The red version of this: http://www.tennis-warehouse.com/adidas_Mens_Fall_Barricade_Seamless_Top/descpageMAADIDAS-AMFBST.html. Sz M but this is smaller than all my other sz M crews. Very nice shirt but definitely fits like a small to me. Too tight. Worn once only. 9.5/10 condition. Asking $25 only. Email firstname.lastname@example.org for details and pics please. Thanks.
