Heard of this?

Has anyone ever heard of the yarn used in this pattern? I have some super chunky stuff i wanna get rid of but it doesn’t look like it’s super chunky. Any info?

I looked it up on Ravelry. The Lana Grossa “Arya Big” is described as being super bulky yarn. Gauge info given is 10 stitches to 4 inches, and suggested needle size is 11 to 15.
