100% cotton. Brooks Brothers plaid straight leg pants, full length pants. Front zip and button closures and both function properly. Belt loops, back button up pockets. No flaws or stains seen or thinning in the crotch area. Since these are all cotton, they do not have any stretch to them. Definitely purely a spring/summer pant….but great for an upcoming cruise or trip to a warmer climate. Measurements: Waist: 16” Inseam: 26.75” Rise: 10” Thigh: 13” Leg width: 8.5”
