The Postalco Free Arm Rain Jacket embodies the primary mission of the company, founded in 2000 by New York-based designer Mike Abelson who wanted to create products built with utility and warmth. Handmade in Japan, the Free Arm Rain Jacket features unique side seam construction, allowing for free and unrestrained arm movement. Meanwhile, the shear-dry nylon shell delivers waterproof protection, and the absence of seams on the shoulders — inspired by the rainwear of Japanese workers harvesting sugarcane in Hawaii in the 1890s — makes for comfortable wear under backpack straps. Additional details on the unisex jacket include sleeves designed to be rolled up for bicycle riding and ring zipper pulls for easy accessibility.
