Our biggest tumbler yet, built for bigger pours. Pack it with ice, top it off with the extra coffee you need to get through the day, and head out or settle in. The Rift Tumbler 20 oz is made for everyday adventure with the confidence of a VaultLoc™ 100% leakproof lid for spill-free carry. The articulated base design provides a comfortable, ergonomic grip, while a slip-resistant silicone bumper keeps the tumbler steady and helps protect surfaces from scratches. Built from durable recycled 18/8 stainless steel with double-wall vacuum insulation, Rift keeps drinks hot or cold for hours in a size that still fits easily in hand and in cupholders. Dishwasher safe and BPA-free.
