HEATTECH XL size white long-sleeved T-shirt. It's fleece-lined and is the warmest type of HEATTECH, the Ultra Warm. I used it for one season last year, along with other items. It wasn't originally pure white, but rather off-white, and it has become slightly dingy overall from use. - Color: White - Brand: HEATTECH - Size: XL Thank you for looking.
