It’s Nitto blue with white.
Two sizes: Med 59cm, to fit most heads and all heads between 22.5 and 23.5-inches around; and Lare 62cm, to fit Rich Lesnik, Harry Hugel, Jay Ritchey, or a normal head with thick hair.
Might be cotton, might be poly, might be a mix. Whatever---it’s nice fabric and a good hat. It’s doubtful we’ll get these in again. They cost a lot and tool a long time to get.
