Ventile® is a densely woven, but unbelievably lightweight cotton fabric developed in the UK during WWII for use in flight suits. We used it to create the ultimate foul-weather lightweight hunting jacket, designed for upland game and estate hunting. Made of pure cotton, the Ventile hunting jacket is entirely wind- and weatherproof, but unlike jackets made from some synthetic materials, it remains breathable and light in any weather. Durable and silent, it's perfect for stalking skittish birds on foggy, wet mornings, but refined and casual enough to wear out on the town later that night. In khaki. Pure cotton. Imported.
