RUFSKIN's patented dual-waist Calkini™ design meets their signature "Pose" fit made from matte finish stretch-nylon in shiny yellow. The hip is thin, designed with a full seat that complements the lined, contoured front pouch. As far as putting them on, lay the piece flat, twist once and align the chic custom engraved chrome D-ring with the other side and step into all at once, you control how the waistbands lay on your body.
