ICIOI 40 oz Tumbler with Handle & Straw — Triple-Wall Insulated Travel Mug, Leak-Resistant Lid

The ICIOI 40 oz Tumbler with Handle and Straw is a large-capacity, triple-wall insulated travel mug with a rotatable leak-resistant lid, ergonomic handle, and complete accessories for comfortable, long-lasting hydration on the go.

This stainless-steel tumbler combines high capacity, robust insulation, and a versatile two-mode lid so you can sip cold or hot beverages for extended periods. Designed to fit most car cup holders despite its size, it includes a handle for easy carrying, a dust-proof straw cap, and a silicone boot for stability. Built from recycled 18/8 stainless steel and made to withstand everyday use, the cup is dishwasher-safe and backed by a lifetime warranty.

How long will the ICIOI tumbler keep drinks hot or cold?

The tumbler uses triple-wall vacuum insulation engineered to preserve temperatures for long stretches. Cold drinks stay chilled through a full day and then some, while hot beverages maintain warmth for several hours.

• Cold retention up to about 34 hours under typical conditions
• Hot retention up to about 10 hours depending on initial temperature
• Triple-wall vacuum construction minimizes heat transfer
• Weld-free interior for better thermal consistency and flavor preservation

Is the lid really leakproof and easy to switch between straw and chug modes?

The patented 2-in-1 lid lets you choose straw sipping or direct drinking without removing the whole top. A thick silicone seal and secure screw-on design prevent accidental pops and keep liquid contained during transport.

• Rotatable lid suited for both left- and right-handed users
• Thickened silicone gasket for reliable leak resistance
• Pop-off proof screw-on closure reduces spills during movement
• Dust-proof cap and soft silicone straw tip for cleaner, more comfortable sipping

What accessories are included and how do they help maintenance?

ICIOI provides practical extras so the tumbler stays usable and hygienic for years. The large-bore straw and brush make cleaning simple, while the silicone boot and handle improve stability and transport comfort.

• Removable wide straw plus straw-cleaning brush for easy hygiene
• Dust-proof straw cap keeps the mouthpiece clean when stored
• Scratch-resistant silicone boot protects surfaces and prevents slipping

How durable and eco-conscious is this travel mug?

• Made from 18/8 stainless steel with about 90% recycled content
