Keep your cranium covered in crazy style with the Flip Your Lid black strapback hat from Killer Acid! This black cap features a traditional strapback silhouette with a five panel crown, a flat bill, and an adjustable strap at the back for a custom fit. Appearing at the front of the crown is an embroidered graphic of a man sweating profusely, and his brain popping out of his head with a big grin on its face, lending your 'fits a dash of bone-chilling flair.
