STANLEY Quencher 30 oz Tumbler — Nectarine, FlowState Rotating Lid & Double-Wall Insulation

Whether you're commuting, working out, or traveling, this 30 oz Quencher balances generous capacity with a slim base that fits most cup holders. Built from recycled stainless steel and engineered for temperature retention, it combines practical details—a comfort-grip handle, a lid that adapts to how you drink, and dishwasher-safe parts—into a daily-carry tumbler made to replace disposable bottles.

How well does the tumbler keep drinks cold or hot?

The double-wall vacuum insulation significantly reduces heat transfer so beverages stay at a usable temperature for hours. Stanley rates the Quencher to keep water cold for up to 9 hours and iced for up to 40 hours, offering dependable temperature performance across different activities.

• Double-wall vacuum insulation for long temperature retention
• Cold for up to 9 hours; iced for up to 40 hours
• 30 oz capacity minimizes refills while remaining portable

What makes the FlowState™ lid different from a regular lid?

The FlowState lid rotates between three positions so you can sip, use a straw, or fully close the top for added protection. The straw opening includes a seal to reduce splashes and to hold a reusable straw in place, while the full-cover position gives extra leak resistance when stowed in a bag or car cup holder.

• Three-position rotating cover: straw opening, drink opening, full-cover top
• Straw opening designed to resist splashes and secure a reusable straw
• Full-cover setting adds leak resistance for travel and storage

Is the tumbler durable and easy to maintain?

Constructed from 90% recycled, BPA-free stainless steel, this tumbler is built to resist stains and odors that plague many plastic bottles. All parts are dishwasher-safe, allowing quick cleanup after a gym session or a long day out, and Stanley backs the product with a lifetime warranty when purchased from authorized resellers.

• Made from 90% recycled stainless steel for long-term durability
• Dishwasher-safe components for low-effort cleaning
• Lifetime warranty through Stanley Resellers for peace of mind

Will the Quencher fit in my car and be easy to carry?

The 30 oz model keeps a narrower footprint at the base so it slides into most car cup holders, unlike oversized bottles that won’t sit flat. An ergonomic comfort-grip handle lets you tote the tumbler without awkward grips, making it convenient to carry through transit, to the gym, or between meetings.

• Narrow base fits most cup holders (except the 64 oz size)
• Comfort-grip handle for easy carrying and one-handed use
• Compact height-to-volume ratio for balanced portability

Who is this for? The STANLEY Quencher H2.0 Flow State Tumbler 30 oz is aimed at people who want a durable reusable bottle that holds a lot of liquid without being bulky. It's well suited for commuters, students, fitness enthusiasts, parents, and anyone replacing single-use bottles with a sustainable, dishwasher-friendly tumbler that stands up to daily wear.
