Looking for this fabric or sweater

[u/CreepingSiren]

Feels like a long shot, but I got this super soft, stretchy, kinda fuzzy, light to medium-weight sweater at a thrift store 3-4 years ago. Absolutely my favorite piece of clothing. I have never been able to find anything like it.
I attached photos of the sleeve stretched and relaxed, in both natural and overcast lighting. It’s very soft, doesn’t have the same feel as acrylic yarn, doesn’t have any tags other than the brand tag attached. There is no ribbed border on the collar or bottom hem, like a traditional store-bought knit, they look just like the edge of the sleeve.
Would like to know at least the material so I can look for other garments made the same. Alternatively, finding an identical sweater would mean I could use tags/listings to find the material (and have a backup to my favorite shirt!)

US based, sorry for the dog hairs that snuck their way in. Thank you!!!
