【Brand Reliability】 Under Armour is known for its high-quality sportswear. In particular, their undershirts are designed to provide both comfort and performance. 【Excellent Functionality】 Made with HeatGear material, they are designed to be comfortable even in hot environments. The compression fit provides a snug fit to the body. They haven't been used very often, and there are no noticeable frays or tears. They were used for soccer, but I think they would be fine for baseball as well. They are the same item. I'm selling them as a set of two. The size is shown in the 3rd and 4th photos, approximately SM. Please note that these are used items, so please only purchase if you are okay with that.
