Not much stretch - for small to medium heads!
Read reviews, and size question response, before buying. BUT they do not fit my "large" head. Wear 7 3/8 man's size hat and XL ladies. Realize outlier but not sure they would fit size 7 head either as not much stretch (thinner material). For women with small and medium heads good value for $ - pretty colors and appear made well.
