Make the high-tech look of the Dreamliner your own. Carbon fibre - the low-density material used in the innovative 787 Dreamliner - is the inspiration behind this one-of-a-kind hat. Features sporty, textured fabric with carbon fibre-look printed panels. Lightweight and breathable, yet structured with a comfortable elasticized flex fit (no clasps or snaps). Embroidered with the Boeing logo. Made from 100% polyester. One size fits most.
