The Wolverine Logo and Image Grey Snapback Cap is made from 100% cotton and may be a byproduct of the Weapon X Program. Hey, it wasn't all about making perfect killing machines like Wolverine...some of it was making fine snap closure hats like this one and some of it was making break up songs for Taylor Swift. See? Top secret programs aren't all that bad. The Wolverine Logo and Image Grey Snapback Cap is a grey hat featuring a light navy Wolverine logo and an image of Wolverine charging forward! He's in line at the Taylor Swift concert.
