You never think you're really going to need one of these things until you do. This seemed to happen a lot when last year we kept getting desperate calls from shoppers who were hoping we had some in stock. We didn't then, but we do now. We swear by the ruggedness, versatility and damn good looks of this essential vest-slash-liner that will increase your warmth markedly and is naturally moisture-wicking. Made with durable 100% virgin Mackinaw Wool, it features a standing collar, handwarmer pockets and a drawcord adjustable-fit waist.
