In the 1970s, Carhartt sent a massive order of coveralls to workers building the trans-Alaskan pipeline. The Yukon Extremes® line was designed using feedback we received from people clocking in to the coldest conditions. This men's warm coat forms a rugged barrier against you and the elements. It has a durable CORDURA® Fabric shell that fights off wind, abrasion, and light precipitation. The arctic insulation inside is the warmest we offer, and the quilted lining is smooth to the touch.
