Purchased this month for 3,839 yen. It's a 3L size, but it was a little small for my husband, so I'm selling it. It's only been tried on after washing. It's thin, so I'll ship it via post. Below is the product page description. Please refer to it. The fabric uses "Nanofine," a nano-level antibacterial treatment. "Nanofine" inhibits over 99.99% of bacteria that adhere to clothing. By inhibiting bacteria, it also provides an anti-odor effect. It uses a Japanese-made processing agent that is extremely gentle on the skin. Because it's knitted with fine-count yarn, it has a fine texture and a sheen. The unique unevenness of the pique knit makes it less likely to stick to the skin, providing a smooth feel. Material Main fabric: 52% cotton, 48% polyester Separate fabric: 63% cotton, 35% polyester, 2% polyurethane Size XXL: Length 72cm, Chest 123cm, Shoulder width 51cm, Sleeve length 26cm
