Due to the material content being different from the Derjon 2.0 on the website, I'm guessing this is the 1.0 version. It is in good condition but is smaller than their normal size S in my opinion, especially in the shoulders and arms. I am between an S and M in Universal Standard and believe this would be better suited to someone who is an XS or between XS and S. Please let me know if you would like more photos or information!
