Uniqlo HEATTECH turtleneck long-sleeved T-shirt, size M in black, excellent for heat retention. - Brand: Uniqlo HEATTECH - Color: Black - Size: M - Style: Turtleneck - Technology: JAPAN TECHNOLOGY I purchased this a while ago, but it's unused. I have the same item in a different color, and it fits snugly against the skin, making it useful as an inner layer. Thank you for looking.
