While each size and shape is perfect for anything you are drinking, there are certainly a few good use cases for each.

The Rambler® Wine Tumbler is aptly named and is ideal for a glass of your favourite vino—whether it’s a Texas Hill Country red or a chilled French white. On the other hand, the Rambler Lowball is perfect for a morning cup of coffee or a few fingers of whiskey in the afternoon. Collectively, they are best used around base camp or where you hang your hat for the evening.

The two larger sizes—591 ml and 887 ml Tumblers—are versatile and are ideal for on-the-go hydration, whether your drink of choice is piping hot or ice-cold. Put anything from a breakfast smoothie to hot tea in either of these and hit the road with a tumbler built to fit in your lifestyle and cupholder.

The short answer is no. While splash-resistant with the MagSlider™ Lid, Rambler Tumblers are not 100% leakproof. If jostled in traffic or knocked over in the boat, some liquid will spill out due to pressure releasing inside the tumbler. For a drinkware option that is 100% leakproof, take a look at YETI Bottles.
