Stop...in the name of Love...before you break my heart! I'm sure that's what Tony Stark is singing on this 100% cotton body/ 100% polyester mesh Iron Man Hand Cannon 9Forty Trucker Hat. Going with that concept, maybe Iron Man has his hand up because there's where his Care Bear Stare comes from! No? Suppose I am letting my imagination run a bit free here. The Iron Man Hand Cannon 9Forty Trucker Hat is constructed by a combination of efforts from Stark Industries and New Era and comes with a snap closure for sizing, a black bill, the image of Iron Man, a white mesh for air flow, and an embroidered Iron Man helmet on the side! You can show Grumpyheart what-fer.
