Britt-approved Say hello to the cold-weather version of our best-selling Britt Utility Work Pant. Built with all the features women love-11 functional pockets, rugged durability, generous stretch, and a women&';s-specific fit that moves with your body-these insulated work pants show up strong when temps drop. We partnered with the wizards at our fabric mill to engineer this pant from the fiber up, based on exactly what working women told us they need in a winter work pant. The result? HOTSWAPA(R)(TM) Stretch Denim: a Dovetail-exclusive fabric that&';s 40% warmer than regular denim, with a brushed interior that&';s super soft, flexible, and never bulky. It looks and feels like your favorite denim on the outside, and works like a performance base layer on the inside. Bonus points for thermoregulation, so you stay warm without overheating when you&';re on the move or working indoors. And because it&';s made with recycled fibers, it works a little harder for the planet too.
