The Hydrojug Traveler 40 Oz Tumbler is a tall tumbler for drinking plenty of water. The permanent handle makes the on-the-go life simple, as you zip from home, to yoga or straight over to work. Hold it upright or down by your side, the lid is leak proof to keep the water inside until you're ready for a sip. Water or other non-carbonated beverages stay super cold inside the triple wall insulated cup, while the rubber bottom prevents it from sliding off car hoods and unbalanced tabletops.
