Our highly constructed, American made, 100% combed cotton twill weighs a stout 8.5 ounces per square yard, providing cast iron durability and versatility year round. It retains a clean sharp crease for days when professionally laundered, or machine-washes to a casual look. All our 100% cotton twills arrive professionally pre-washed to stabilize sizing and will wear like your old favorites from the first time you put them on. Machine washable. Made in USA.
