The Sud Scrub is an antimicrobial silicone body scrubber made of non-toxic, food-grade silicone that's infused with antimicrobial silver and zinc to resist odor-causing bacteria, mold, and mildew from growing on its surface. It is designed to exfoliate, massage, and provide a superior lather, while being eco-friendly and 100% recyclable. Customer reviews are generally positive, with users praising its exfoliating and cleansing properties, although some have mentioned that they wished it was a little rougher on the skin for a more intense scrub.
