Are YETI Tumblers dishwasher safe?
Yes. We recommend lids on the top rack, and gaskets and magnetic slider in the utensil's basket. Of course, you can always hand wash, but we know you're busy on your next adventure.
Do YETI Tumblers fit in Cupholders?
Yes. Our stainless steel tumblers are designed to join you on the drive, in the boat, and around the fire and should fit in most cupholders. The two larger sizes— 20 oz. Tumbler and 30 oz. Tumbler —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. Our travel mug also fits in cupholders
Are they Leakproof?
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.
