Thunderpants are made with our own blend of super stretchy organic cotton and spandex fabric. They are comfy, wedgie-proof, and there is no scratchy elastic that digs in. The ultimate comfy easy-fit undies! The Original, Hipster, and Sky Rise styles all have the same fit through the leg and bum with varying height. The Hipster is low waisted, the Original sits around the navel, and the Sky Rise is high waisted. The Boxer Brief is a mid-rise short leg trunk style. Welcome to ultimate comfort.
