STANLEY IceFlow 2.0 Flip Straw Tumbler 40 oz — Dried Pine, Recycled Stainless Steel & Leakproof Lid

The STANLEY IceFlow 2.0 Flip Straw Tumbler is a 40 oz recycled stainless steel travel cup with a quick-flip built-in straw, a leakproof shut, and long-lasting cold retention.

Designed to keep large-volume beverages icy for extended periods while fitting everyday routines, this tumbler updates STANLEY’s classic durable build with recycled 18/8 stainless steel and a redesigned Flip Straw 2.0 lid. It slips into most cupholders, offers a wide mouth for easy filling and ice, and includes a comfortable carry handle so you can grab and go. The lid’s removable spout and replaceable seal simplify cleaning and maintenance, and the tumbler is dishwasher-safe for low-effort care.

How quickly can I take a sip and secure the tumbler during transit?

The Flip Straw 2.0 lid lets you flip the straw up to drink instantly and snap it closed to create a fully leakproof seal. That fast-action mechanism is built for moving between errands, workouts, or commutes without fuss. The lid also has a removable spout for thorough cleaning and a replaceable seal to maintain leak resistance over time.

• Flip-up straw for single-handed sipping
• Snap-shut lid that locks out leaks when closed
• Removable spout and replaceable seal for longevity
• Cupholder-compatible base for vehicle use

How long will drinks stay cold or iced inside the 40 oz tumbler?

Double-wall vacuum insulation slows heat transfer so cold drinks stay refreshingly cool; expect cold retention for about 20 hours and ice preservation for up to several days under typical conditions. That performance makes the tumbler useful for long outings, desk use, or multi-hour travel where access to refrigeration is limited. Keeping the lid closed when not sipping helps maximize insulation.

• Double-wall vacuum insulation for extended cold retention
• Large 40 oz capacity reduces need for frequent refills
• Wide opening accepts full ice cubes or crushed ice
• Stainless-steel interior avoids flavor transfer

What materials and cleaning options does the tumbler offer?

The tumbler body is crafted from recycled 18/8 stainless steel for strength and corrosion resistance, while all components that contact liquids are BPA-free. It’s designed to be dishwasher-safe, and the Flip Straw 2.0 lid breaks down for hand or machine cleaning. Replaceable parts help the product stay functional for years rather than being disposed of after wear.

• Recycled 18/8 stainless steel construction
• BPA-free plastic lid components that are dishwasher-safe
• Removable spout for deep cleaning or replacement
• Replaceable seal to extend usable life

Will this tumbler fit in my daily carry and backpacks?

The 40 oz IceFlow 2.0 is engineered with a slim, cupholder-friendly base and a large ergonomic handle for easy transport. It tucks into most vehicle cupholders and clips or carries comfortably in hand or on a strap. Despite the large capacity, the tumbler’s shape balances volume with practical portability.

• Base designed to fit standard car cupholders
• Easy-carry handle for one-handed transport
• Balanced shape to avoid tipping in bags or consoles
• Lid locks shut to prevent spills when stowed

Who is this for: The STANLEY IceFlow 2.0 Flip Straw Tumbler is a fit for commuters, outdoor enthusiasts, gym-goers, and anyone who prefers a large-capacity drink container that stays cold for hours and resists leaks. It’s also a practical choice for people seeking a durable, easy-to-clean bottle made with recycled stainless steel and replaceable parts for longer product life.
