Lightweight, relaxed-fit shell pants built for warm-weather wear Blending the ruggedness of their Midwestern heritage with a nearly obsessive attention to detail, Relwen creates menswear that lasts. Taking cues from military utility pants built for the tropics, the Relwen Military Roll Up Pant updates that classic silhouette for the modern age. Cut from an ultralight cotton and nylon shell fabric, these drawstring-waist pants have a relaxed, tapered fit and a roll-up button feature at the hem designed to stay out of your bike chain’s way.
