Our expert sourcing team seeks out the highest quality fabrics left over from factory production, burn testing each textile to assure that it is at least 90% natural, plant-based fiber. We recommend machine washing in cold water and hanging to dry. This is the best way to care for your pants—and the earth. Iron on medium heat if needed. Fabrics are pre-washed and shrunk, but may shrink slightly if machine-dried.
