Size: To determine which size to order, measure around your hips at the point you would want to wear the harness.
X-Small fits 26″-30″
Small fits 28-48”
Medium fits 34-54”
Large fits 38-64” (can stretch to 68”)
X-Large fits 42-46″ and can stretch to 72″
Please keep in mind that the waistband is elastic and therefore very stretchy. If you are in between sizes, it is best to choose the smaller size.
