from the manufacturer: "Iconic waxed trucker jacket, flannel-lined for warmth and comfort Tough, timeless, and made in the USA, this men’s waxed canvas jacket is constructed with a waxed and weather-resistant Martexin 7 oz. sailcloth, which like selvedge denim or finely tanned leather, will only get better with age. With every adventure, the waxed fabric will develop a unique patina, creasing and bending to mark your own unique wear patterns. It's truly a thing of beauty and why every guy needs a Waxed Trucker in their closet. And unlike most of the other Waxed Truckers on the market, this jacket is soft out of the box and can even be worn only with a tee underneath since both the body and sleeves are made with a soft blanket lining. For the price, you simply can't beat the quality, construction, and versatility of this bad boy."
