I have a massive head too (7 3/4 or 62cm). The only hats that fit me are either fitted 59Fifty baseball caps (but not buyin American anymore) or XXL Flexfit caps which A) only come in basic polyester/cotton/elastane blend and solid colors so tough shit if you want fun colorways and/or technical materials and B) are super affordable and supremely comfortable.
