These are 100% cotton and are brand new. Although they are marked 36x34, these are actually more of a 35x34 size. I purchased these, but by the time I went to use them, the return period for Aramark had expired. Even though they are suppose to be 36" waist, and are only 35", Aramark would not exchange or refund them. Here are the features from the Aramark website:
"Neat, flat-front styling with permanent, built-in creases
Exclusive finish eliminates ironing, protects pants from staining, fading and shrinking
Extra durable stitching in seat for strength
Rust and break-resistant brass ratcheting zipper
Unbreakable melamine buttons
Solid-core threads, spun-wrapped for a softer feel
Reinforced deep front pockets
Two back set-in pockets
Industrial launder or machine wash, dry"
 
Will ship either USPS Ground or UPS Ground, depending on shipping location.
