This harness is fully adjustable thanks to buckles at the hips and crotch. It has two straps at the back that can be adjusted in 4 positions. It can be adjusted from a size S (80 cm) to a size L (100 cm). Six holes in the belt allow for adjustable sizing. The O-ring is perfect for inserting a dildo smaller than 45 mm (not included).
