Unlined Teat-drop crown 100% Genuine Panama straw Designed in London, Hand made in Ecuador 9cm brim width for sun protection Small: 56cm Medium: 58cm Large: 60cm XL: 62cm Straw hats typically do not require washing, as the material can be sensitive to water and may lose its shape or durability if submerged. However, the sweatband inside the hat can be cleaned with a damp towel to remove sweat marks or makeup residue. Gently wipe the sweatband with the damp towel, being careful not to saturate the straw material. Allow the sweatband to air dry completely before wearing the hat again to ensure it maintains its shape and quality.
