80stees now has Grimlock & Optimus Prime Hoodies! both retail for $60, Grimlock is available now, while Optimus Prime is coming soon!
I've got about 20-25 Transformers Tees from them, unfortunately hoodies cost a lot to ship abroad. These look cool, but I wouldn't walk around with the hood on over here, lol.. Hope they add some decepticon ones soon. They have some new Transformers Tees as well..
