I don't think we can say 'made from 100% cotton' about too many Transformers, but we can about the blue flat billed red bodied Transformers Optimus 9Fifty Snapback Cap from New Era! Yowzah, that's a mouthful. Still, you really have to appreciate the battle ready Optimus Prime on the front of this great hat...though it doesn't make the sound effect. Sorry! There's only so much we can do, my friends. The Transformers Optimus 9Fifty Snapback Cap also has one of those fancy snap closures for perfect sizing and is of exceptional quality!
