Style 8631 Low rise and moderate coverage No-fly design We've given our Jockey FormFit Lightweight Seamfree Bikini an ultra-comfortable upgrade. It's softer and lighter than our previous Seamfree underwear, thanks to its premium yarn. But what hasn't changed is an unrivalled fit, and a Seamfree and tag-free design that won't rub you the wrong way as you move through your day.
