This body strap harness is made from super soft, quality lamb skin leather. All edges are rolled and stitched with the highest quality European craftsmanship. Adjustable back buckle closure plus elastic back middle strap allows for a comfortable fit for most. Not a thong back, straps lay over the cheeks, leaving the crotch area fully exposed. This is not a faux leather toy. This possesses quality and comfort to be worn under anything or without anything and it softly snugs and restrains in all the right places! Strong enough to be tugged and pulled during some light rough play.Size Chart
