The thickness may vary on a bolt by bolt basis. I recently bought two 2 1/2 yard pieces - one a printed Anti-pill and one a solid Blizzard. The Blizzard was much thicker and while folded it took up at least 1/3 more space in the bag. Doing a machine blanket stitched hem on the Blizzard was much easier. The Anti-pill was so thin it wanted to distort the edge. Last year's Anti-Pill was a little thicker, but nothing like any fleece was 10 years ago.
I'm not familiar with the Luxe. Road trip time. My nearest JoAnn's is 50 miles away.
