This item was purchased about 10 years ago at the Under Armour store in Shibuya, which has since closed. I believe it was a collaboration item between Under Armour and the movie Avengers: Age of Ultron. It features a Captain America design, with iconic designs on the chest, back, and shoulders, making it very cool. I've worn it a few times, so please consider it used clothing. There are no noticeable stains, marks, or tears. The size is S, as shown in the photos. It's an American size, so for me, at 172cm and 65kg, it fits a bit tight, creating a body-hugging silhouette. It's the kind of fit someone who wants to show off their muscles would choose. Type: Undershirt Popular Model/Series: HeatGear Sleeve: Short Sleeve Gender: Men
