After talking with a separate representative they immediately sent me the correct size and very promptly, I'd like to retract my previous review, I was overly harsh on Crunchyroll due to a worker not being able to help me properly. The actual hoodie is a really nice material but it isn't extremely thick. It's a very good "all-around" hoodie.
Thank you for the update! We want everyone who purchased these limited edition collections to be happy - so I'm so glad that you like the hoodie!
