NWT Carhartt Sandstone Quilted Flannel Lined Active Jacket We debuted our first active jac in 1975 as a response to cold Detroit winters. Decades later, the design stays true to the utilitarian style and legendary toughness that made it one of our most popular items. This men's durable flannel-lined version keeps you warm and fights off wind and cold. It's made with heavyweight duck that's been sanded and brushed, giving it a soft feel from the start. 29” Long NWT! There is a name patch on lining, but it’s never been worn.
