This is a lighter weight hat made from linen, hemp, cotton & bamboo.  The off white cream colored section is undyed hemp, the variegated section around the top is a blend of linen, hemp, cotton and bamboo, and the yellow is a blend of cotton and bamboo. The thin white accent stripes are bamboo, and the beige stripe bordering the variegated section is undyed colorganic cotton.  Bamboo looks a lot like tussah silk, which has a nice subtle sheen to it.  Should cover most of the ears, fits a 22 - 23 inch head, and is fine for either gender.
