Thank you for viewing. This is the Montbell Field Umbrello. It's a cool and comfortable "Kasa" (Japanese hat) type hat made with natural grass. It has space above the head, making it less stuffy and comfortable to wear even in midsummer. The natural grass is woven with a core thread, making it resistant to deformation. 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) Material: Hat body: Natural grass (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 a waterproof performance similar to that of a rain umbrella. patagonia MILLET L.L.Bean THE NORTH FACE MAMMUT mont-bell ARC’TERYX karrimor Columbia Outdoor Camping Travel Hiking Trekking Mountaineering Sun visor Sunshade hat Sun protection cap Straw hat
