"Blend" is 63% poly, 34 cotton, 3 P.U. spandex, made in Bangladesh. Excellent "Extra Big" XXL cap *for me*. Everyone's head and likes are different, but I've tried a few Flexfit caps and this is the best after One Day. I wanted no mesh, no trucker panels, no flat bill/brim. For me, a cap must not only fit in circumference but must also come down far enough, not sit up like a beanie (like the 6997 Flexfit Low Profile). Check! It must have a softly curved brim, not so curved that it dents into my temples (like the Premium Original Flexfit V-Flexfit Cotton Twill Fitted Hat 5001 XX). Check! It must have a crown that sits up in a middle height (unlike the low 6997) and not stick up stiff like you see on most service people. My old favorite the Flexfit W06S36F has a softer floppier crown than this, undecided for now which i like better. My only quibble with this cap is the color choices.
