Athletic Bilbao home jersey in perfect condition, with all the details highlighted, without discolorations or abrasions. The technical sponsor Adidas made this shirt for the 1999/2000 season, size M.

With red and white vertical stripes, the shirt features the football club's crest sewn both on the heart side and at the bottom right, in a box where the lettering of the technical sponsor Adidas is jointly represented. The logo of the technical sponsor, in black, is instead applied to the top right. The collar is placed on a V-neck, while the name of the Spanish club is applied to the back. The stripes of different sizes, compared to those depicted on the entire shirt, present on the shoulders and on the sides of the arms represent one of the most peculiar characteristics of the shirt.

The Spanish team finished eleventh in the Primera Division championship in the 1999/2000 season and played in the round of 32 of the Copa del Rey, under the guidance of coach Luis Miguel Fernández.
