STANLEY IceFlow 2.0 Flip Straw Tumbler 40 oz — Dried Pine, Leakproof Flip Straw & 20‑Hour Cold

The STANLEY IceFlow 2.0 Flip Straw Tumbler is a 40 oz recycled stainless steel travel cup with a flip-up straw lid that seals leakproof and keeps drinks cold for extended periods.

Built to handle busy days and outdoor adventures, this Dried Pine 40 oz tumbler combines durable recycled 18/8 stainless steel with double-wall vacuum insulation and a redesigned Flip Straw 2.0 lid. It fits most vehicle cup holders, has an enlarged opening for easy filling and ice, and includes a large carry handle for one-handed transport. The lid’s removable spout and replaceable seal simplify cleaning and maintenance, making the tumbler a practical companion for daily commutes, workouts, and travel.

How does the Flip Straw 2.0 lid make drinking faster and tidier?

The Flip Straw 2.0 lid is engineered for quick sips and secure closure. Flip the straw up to drink, then snap it down for a fully leakproof seal—ideal for tossing the tumbler in a bag or setting it in a cup holder without worrying about spills.

• Flip-up straw for immediate access during movement
• Snap-shut mechanism creates a 100% leakproof closure when closed
• Removable spout piece for straightforward cleaning
• Replaceable seal extends lid lifespan and hygiene

What temperature performance can I expect from this 40 oz tumbler?

Thanks to its double-wall vacuum insulation, the IceFlow 2.0 preserves beverage temperatures for long periods. It’s designed to keep cold drinks chilled throughout the day and ice longer than a standard cup—helpful for hot weather, long trips, or multi-hour activities.

• Cold retention rated up to 20 hours for chilled drinks
• Iced contents stay frozen for multiple days under typical conditions
• Insulated walls prevent exterior condensation and hand chill
• Wide mouth accepts large ice cubes to boost cooling longevity

Is the tumbler convenient for everyday and outdoor use?

The design prioritizes portability and real-world usability. A comfortable carry handle and cupholder-compatible base make it easy to take the 40 oz tumbler to the gym, the office, or on road trips. The recycled stainless steel construction balances toughness with conscious material choice.

• Large loop handle for secure, single-hand carrying
• Base shaped to fit most car cup holders and drink mounts
• Dishwasher-safe components for low-effort cleaning
• 18/8 recycled stainless steel resists dents and corrosion

How easy is it to clean and maintain the IceFlow 2.0?

Maintenance was a focus in the redesign: the spout removes for washing and the lid includes a replaceable seal so you can swap a worn gasket rather than replacing the entire lid. Most parts are dishwasher-safe, helping you keep the tumbler sanitary with minimal fuss.

• Removable straw spout detaches for deep cleaning
• Replaceable silicone seal reduces long-term cost and waste
• Dishwasher-safe stainless body and lid components for convenience
• Wide opening allows easy scrubbing and ice removal
