The front pad of this harness is cut from sturdy latigo leather, and the hip straps and leg are made from strong oiltan. We use soft garment leather for the center G-string, and we finish it with smooth, sewn edges. The straps easily adjust to fit up to a 40" hip or waist, depending on how you prefer to wear your harness. Although any 1.5" diameter dildo will work in our harnesses, we've found the best comfort and performance comes from the dildos we've created specifically for harness use. The dildo included with this harness has a specially shaped base that perfectly matches the snapping pad on the harness, so the dildo will fit securely without rotating or slipping. Heavy-duty snaps on the base pad of the harness are a simple way to attach and remove your toys. So experiment with dildo styles, and do it with style in a Spartacus harness!
