Iconic brand Postalco has developed a water-resistant rain jacket with a sleeve construction that allows for fuller and more unrestrained arm movement. The side seams have a special construction allowing exceptional ease of movement. Japanese workers harvesting sugarcane in Hawaii in the 1890s inspired the no-seam shoulder construction. The rain jacket is unisex and available in two sizes, medium and large, which accommodate a range of body types. A ring zipper pulls to open pockets easily. An elastic waistband in the back may be used to tighten or loosen the jacket. Made with Postalco's original Shear-Dry nylon, which blocks 95% of UV rays. Handmade in Japan.
