65% cotton, 35% linen. Woven twill fabric. Mid rise. Back pocket on right side. Two front slash pockets. Elasticated waist with drawstring fastening. Relaxed tapered fit. The Alva Skate Pants are a laid back pair of action slacks from Y.M.C. They’re made out of some ultra-relaxed woven twill fabric, and thanks to that tasteful bit of elastic, they’ve got a fair bit of stretch to ‘em. They’ve also got an elasticated waist for big meal comfort.
