Built for warm days when you still want coverage, the Patagonia Men's Lightweight All-Wear Unlined Jacket keeps things cool, comfortable, and easygoing. Its soft and breathable blend of organic cotton, hemp, and a touch of spandex offers natural airflow with stretch, while the unlined design prevents overheating. A snap-front placket, lie-flat collar, and elasticized cuffs deliver simple, reliable function, and the adjustable drawcord hem lets you dial in the fit. Two front on-seam pockets and two interior drop-in pockets keep everyday essentials close.
