Long-sleeved black polo shirt, Under Armour UA Playoff Wordmark Long Sleeve Polo Originally priced at 9900 yen. https://www.underarmour.co.jp/f/dsg-1068967 (The linked page shows a different color. It seems black is out of stock on the official manufacturer's website.) I am 172cm and 70kg, but it was too big for me, likely due to the LOOSE fit. I think it would fit someone 175cm or taller better. I only tried it on once and haven't used it.
