Using this bottle is a breeze. Simply unfold the drinking tube and take a sip whenever you're thirsty. When not in use, fold the tube back in to keep it clean. As for the foam part, you can roll it on your muscles after a workout for a relaxing massage. To maintain the bottle, wash it with mild soap and warm water regularly. Avoid using abrasive cleaners as they may damage the steel or the foam. And make sure to dry it thoroughly before storing to prevent any mold growth.
