This waxed insulating layer, sometimes known as a “bodywarmer,” lives up to its name thanks to a Thinsulate filling and durable, water-resistant finish. The latter is courtesy of British Millerain, the original manufacturer of waxed cotton for outerwear. Centuries of expertise ensure your Waxed Cotton Vest ages as well as it performs, acquiring character and patina. It's the right piece to stand between you and the elements.
