Hats off to the designers of this harness! The 1-3/4" O-ring of the Terra Firma snaps out for adjustability, the waist and leg straps connect directly to the ring for rock solid stability, a pad protects your private fur from your dildo's base and can be removed for use with a double header dildo. Plus, the two-strap design and adjustable D-ring fasteners allow for a perfect fit. There's even room for the balls of the realistic toys some of you love. Fits up to 44" hips. Dildo not included.
