With initials that stand for Rugged Outdoor Chino, the Columbia ROC Pant is exactly that. Built from durable, 100% cotton Granite cloth, these handsome pants are buttery soft but tough enough to handle pretty much any outdoor activity, everything from raking leaves to off-trail bushwhacking. Featuring Omni-Shade UPF 50 sun protection and a zip-closed security pocket. Material: Cotton.
