Big enough for a full morning brew yet built tough for the road, the Rift Tumbler 16 oz is made to keep up with your day. The VaultLoc™ twist-lock leakproof lid delivers peace of mind with every sip, while the articulated base design offers a secure, ergonomic grip. A slip-resistant silicone bumper protects surfaces and keeps the tumbler steady on the move. Constructed from durable recycled stainless steel with double-wall vacuum insulation, Rift locks in heat or cold for hours, giving you reliable performance in a larger size.  Dishwasher safe and BPA-free.
