The Sefa Straw Sun Hat in natural from Helen Kaminski is constructed from a fine grade raffia from Madagascar. The body is made of a hand-crochet stitch that has no interior knots, therefore providing extreme comfort. Any dimpling from packing can be lightly steamed or will disappear with body heat. It's the perfect hat for travel because you can roll it, pack it, and travel. The 9cm wide brim is very malleable and can be shaped and adjusted for individual style. The traditional raffia string surrounds the 10cm high round crown to help adjust the fit when necessary. 100% raffia straw. Inside the crown is a neoprene band for a comfortable fit upon the forehead. The metal Kaminski Raffia Seed insignia is pinned onto the hat. Size: One size fits most, adjust to fit; fits up to 57cm comfortably. Comes with a lovely bag which your hat can roll into, perfect for travelling!
