Thank you for looking. This is a Montbell Field Umbrello. This is a "kasa" (traditional Japanese umbrella hat) type hat made of natural straw, designed to be cool and comfortable. It creates space around the head, making it less stuffy and comfortable to wear even in midsummer. The natural straw is woven with core threads, making it resistant to losing its shape. It comes with a rain cover that can be stored inside. It also has loops for attaching a hat screen (sold separately). Specifications (quoted from the brand website) Materials: Hat body: Natural straw (pandan) x polyester Cover: 70-denier nylon ripstop [acrylic coating] Weight: 135g Color: Turquoise (rain cover) Size: Free size, Diameter 45cm Features: Includes rain cover / chin strap (safety design with a hook that detaches under heavy load) *The rain cover is not waterproofed at the seams, but it has the same level of water resistance as a rain umbrella. patagonia MILLET L.L.Bean THE NORTH FACE MAMMUT mont-bell ARC’TERYX karrimor Columbia Outdoor Camp Travel Hiking Trekking Mountaineering Sun visor Sun hat Sun cap Straw hat
