The tights for the cold walk to the bus stop

These tights are 80 denier, which the listing calls medium thickness, in a solid opaque color. The fabric is 85% polyamide and 15% elastane, made from a soft microfiber yarn, so a skirt or dress can stay in your rotation when the weather turns.

The numbers that matter are on the label. The blend is 85% polyamide and 15% elastane, and the listing describes the yarn as super soft microfiber. Polyamide is a nylon family fiber and elastane is the stretch fiber. At 80 denier the thickness is medium, and the color is solid and opaque, so there is no sheer finish to think about.

The listing says the knit uses 3D spandex technology, which it describes as stretchable in all directions with a better fit. Sizing is given by height and weight. S/M covers 5'0" to 5'6" and 90 to 130 lbs. L/XL covers 5'3" to 5'10" and 120 to 180 lbs. 2XL/3XL covers 5'3" to 5'11" and 170 to 240 lbs. The ranges overlap, so if you sit near an edge, check both.

Care is listed as machine wash, and the item is imported. The listing does not state a wash temperature, a waistband or toe construction, or whether there is a control panel, so those stay open questions. None of that is a flaw, only a gap in what the listing tells you. It is also sold in Cream, Olive Green and Fuchsia, and which of those suits your wardrobe is a matter of taste, not measurement.
