Men's Kapok Blend Straight Denim TrousersPants designed with a straight silhouette that gives you room to move comfortably all day. By using a fabric that mixes organic cotton with natural kapok fiber, an environmentally friendly plant grown without pesticides, it is softer and lighter than conventional 100% cotton. [What is Kapok] The fiber harvested from kapok nuts is a material with minimal environmental impact that can be cultivated with little fertilizer and water without pesticides.
