Stio Grey Shorts. From the office to the skate park to the summer road trip, the Rivet Canvas Short is a do-it-all summer essential that offers the perfect blend of rugged durability and stretchy comfort. These shorts are built with the same Drover™ organic cotton canvas fabric as our bestselling Rivet Canvas Pant.

A classic belt-loop waist and bartack-reinforced hand pockets complete this versatile, reliable look.
