STANLEY Quencher H2.0 Flow State Tumbler, 20 oz Seafoam — Insulated Stainless Steel with Spill‑Resistant Rotating Lid

The STANLEY Quencher H2.0 Flow State Tumbler (20 oz, Seafoam) is an insulated travel cup with a rotating FlowState™ lid that offers sip, straw, and full-cover positions for spill resistance and easy carrying.

Designed for commuters, gym-goers, and anyone who wants a reliable reusable cup, this 20 oz Seafoam tumbler blends durable, mostly recycled stainless steel construction with double-wall vacuum insulation. Its narrow base fits most car cup holders and the ergonomic handle makes it simple to tote. The FlowState™ lid adapts to how you like to drink while helping reduce spills and keep beverages at the preferred temperature for hours.

How does the FlowState™ lid adapt to different drinking styles?

The FlowState™ lid rotates between three positions: a straw opening with a splash-resistant seal that secures the reusable straw, a direct drink opening for larger pours, and a full-cover top for extra leak resistance. Switching positions is intuitive and keeps the cup usable in more scenarios, from walking to driving.

• Straw position: sealed edge to reduce splashes and hold the straw in place
• Drink position: wider opening for quick sips or larger gulps
• Full-cover: closes the top to limit leaks and protect contents

How well does the 20 oz model control temperature?

The tumbler uses double-wall vacuum insulation to slow heat transfer, keeping cold drinks iced and warm drinks at a comfortable temperature for extended periods. While exact duration varies with ambient conditions, you can expect noticeably longer temperature retention than single-wall containers.

• Double-wall vacuum construction for thermal performance
• Stainless-steel body resists staining and odors
• Suitable for iced beverages, water, coffee, and more

Stanley constructs the Quencher H2.0 from 90% recycled, BPA-free stainless steel for strength and reduced environmental impact. The metal build resists dents and long-term wear, replacing single-use bottles while offering a lifetime warranty when purchased from official resellers.

Is the tumbler easy to clean and use every day?

• Dishwasher-safe components for convenient cleaning
• Narrow base fits most car cup holders (except 64 oz model)
