This heather blue gray wool polyester knit is lightweight and not scratchy like many wools. I don't know how much is wool and how much is polyester, but if feels like a thin wool knit and doesn't feel at all like polyester. It's somewhat sheer when held up to the light, but probably wouldn't be noticeable on the body. Has tiny white dots scattered throughout.
Length: A bit over 2 yds Width: 59" Stretch: 30% crosswise, 10% lengthwise
