Quick Duck® is 30% lighter than sandstone duck, but ounce-for-ounce just as durable without the bulkiness. This Carhartt snowsuit is made of 8.5-ounce, 60% cotton/40% polyester canvas and features Rain Defender™ durable water-resistant finish and Stain Breaker™ technology that helps release stains in the wash. It has a diagonal full zip for easy entry/exit, quilted taffeta lining for warmth. A gusseted crotch diminishes ride up, and provides extra room and mobility. There are hidden rib cuffs at sleeves and legs for extra warmth.
