So I finally got the Vow hoodie after about 3 weeks delay. They shipped it out to me on the first and it got here earlier this morning. I do really love the hoodie, my only issue is that price of $50. Definitely not worth that much. $30 would've been more reasonable, especially since you can't add your PSN ID or Gamertag to it.
Mine is an XS as I am a skinny 5'3". It's thinner than I thought it was gonna be but I kind of prefer that despite living in Denver.
I wish this hadn't been an "exclusive" item requiring the code but hey, one more piece of Destiny merch you can't get anywhere else. Kind of cool at least!
