TIGORA Heattech Thick Undershirt, Size 140. - Color: Black - Size: 140 - Style: High Neck - Material: Polyester This is a thick undershirt, purchased to wear under a T-shirt for a futsal experience. I also wore it once under snow wear for playing in the snow. After that, I found it very useful, wearing it under a sweatshirt on quite cold days, as it's thick. This item cost a little over 4000 yen at the sports store. Thank you for looking.
