This high rise style is my favorite. Feels like wearing nothing. I have warm sand and black in this panty. I won't leave the house without wearing them. I use the leakproof feature for light bladder leaks. They wash up well. I hang to dry to help with keeping them in shape. A must for us mature ladies. Confidence and security all in one!
