Heattech Ultra Warm Tights, XL size, Black. Set of 2 (different models)! UNIQLO Heattech Ultra Warm Tights Size: XL Men's Color: Black Extra Warm Not the 2025 model. Also, they are not the same model number. The retail price is also different (see image 4). The contents are the same. The boxes appear to be different sizes, but they are the same size. This is because they were purchased at different times. Sorry for the confusion. Set of 2!
