ACTIVE TUMBLER is designed to help you elevate your energy. The straw-type spout is easy to open and comfortable to drink from. The tumbler has a wide opening so it is easy to put in ice cubes and drinks. Vacuum insulated tumbler retains the temperature of cold drinks for a long time, and the elastomer rubber on the bottom reduces impact when placing the tumbler on the floor. It is available in 600ml and 800ml sizes.
