Here at REVOL, we believe that not only should we feel completely protected during our cycle, but we should feel comfortable and empowered at the same time. Each pair of underwear is designed to be worn on it’s own, and paired with your flow, with the heavy protection level undies worn on your heaviest days, the medium protection level on your medium day, and the light protection level on your light days! Our size ranges from 2XS-8XL but we want to empower women of all shapes and sizes, so feel free to contact us at info@revolundies.com if you have any special requests.
