Last season, there was a collaboration between Pokémon Pikachu and the Yokohama DeNA BayStars, and this is a very valuable and rare item with the exact same design and material as the ones actually worn by the players during practice. I have included many photos of the players wearing it, so please take a look. Purchase is from the Yokohama DeNA BayStars official online store. It is an opened, unused item. I have decided to sell it because I have kept it folded for a long time and don't think I will wear it. The size is L. Actual measurements are approximately 114 cm for the chest width, 71 cm for the length, and 48 cm for the shoulder width (straight line). Please consider that there may be some slight variations. Especially for the chest width, it is measured at the point that touches the skin underneath, as the armpits have a double layer construction. It looks very cute even if a woman wears it oversized. The armpits, etc., are made very carefully and meticulously. It is made of a cool, sturdy material that dries sweat quickly. It is made of a truly durable material that can withstand professional baseball players' practice.
