This is the version, without Acne tags. The seller claims this is 30% mohair, just like the original Acne sweater. In hand, this is very close to the retail version, and it's definitely a high quality rep overall. It doesn't come with any of the original tags and is considerably small in size compared to the original oversized-look. Note that I included a retail product shot to compare, the rest are from the warehouse. The retail version is $400 at the moment.
I've seen similar versions of this sweater on Taobao, but they are most likely from this same batch.
