Inspired by the classic trucker cap, Hangover is is made from cotton and polyester – durable materials which will let you make a statement year-round. Its flat bill protects your face from the sun while the plastic mesh back provides breathability, reducing sweat – perfect for a hot summer day! The snapback closure is adjustable in size, making this a one-size-fits-all (or one-size-fits-most) baseball cap that’ll stay well-adjusted for all-day comfort.
