This body strap is made from super soft, quality lamb skin leather. All edges are smooth, clean cut leather edges. 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. Try it under your favorite jeans and a blazer for a night out you'll be amazed at the result.... Ones size fits most with adjustable buckles.
