This cap has the mesh back panels and snapback closure of a trucker hat but with a lower-profile fit more like a ball cap. The precurved bill can be bent to suit your sense of style (or lack thereof) but it probably won't go full flat-bill for you. Sorry, bruh. Write your name, rank and serial number on the embroidered name patch, draw a pretty picture or leave it blank and let the sweat rings go to work.
One size fits most.
