Advanced FlowState Lid

The standout feature is the rotating FlowState lid, which features three distinct positions:

  • The Straw Opening: Features a silicone seal designed to hold the reusable straw firmly in place while resisting splashes.

  • The Drink Opening: A wide-mouth slot for direct sipping.

  • The Full-Cover Top rotates completely shut to minimize spills and leaks when you are on the move.

Premium Insulation & Materials

Constructed from 90% recycled, BPA-free 18/8 stainless steel, the Quencher is built for sustainable durability. Its double-wall vacuum insulation delivers long-lasting temperature control:

  • Cold liquids: Stays chilled for 9 hours

  • Iced drinks: Keeps ice solid for up to 40 hours

  • Hot liquids: Keeps drinks warm for 5 hours

Built for Travel

Unlike bulky jugs, the 30 oz Quencher features a distinct tapered shape. The narrow base (roughly 3.15 inches in diameter) is engineered to fit into standard automotive, stroller, and gym equipment cup holders. It is paired with an ergonomic, comfort-grip handle that makes lifting and carrying effortless.

Clean & Care

The tumbler is entirely dishwasher safe, meaning you can toss the body, lid, and reusable straw right into the machine without worrying about ruining the vacuum seal or the powder-coat finish.

Note on Leak Resistance: While the H2.0 generation features improved silicone seals around the straw opening compared to the original version, it is still a splash-resistant tumbler rather than a 100% leakproof thermos. It will handle minor bumps, but may leak if flipped upside down in a bag.
