This is the cotton seersucker ivy cap made by Wigens, the 107 year-old haberdasher from Tranas, Sweden. Royal Warrant holder to the King of Sweden, Wigens is widely regarded as one of Europe's finest hat makers, based on its founder's insistence that each cap had to be absolutely flawless. Originally sought by Colonial Britain for use in tropical climates, seercucker's slack tension weave creates a bunched, crinkled hand that causes the fabric to be held away from the skin, improving air circulation. Made from 67% polyester/33% cotton, this cap's classic striped pattern bears the same crinkled hand that keeps your head cool. Its nylon mesh liner dissipates heat for additional ventilation. Machine washable. Blue/white striped. (3 oz.)
