Hydro Flask Travel Tumbler 40 oz Seacliff – Insulated Stainless Steel with Handle & Straw Lid, Cupholder-Friendly

The Hydro Flask 40 oz Travel Tumbler with Handle, Lid and Straw is a double-wall insulated stainless steel cup built to keep drinks cold for hours while offering a comfortable handle, leak-resistant straw lid, and cupholder-friendly shape.

Whether you're commuting, hiking, or sitting at your desk, this 40-ounce Hydro Flask Travel Tumbler is designed to reduce refills and keep beverages tasting fresh. Its TempShield double-wall vacuum insulation maintains cold temperatures, the durable pro-grade stainless steel prevents flavor transfer, and the ergonomic handle plus flexible straw lid make sipping convenient on the move.

How long will my drink stay cold in this tumbler?

The TempShield double-wall vacuum insulation slows heat transfer so cold drinks remain chilled for hours under typical daily use. Performance depends on starting temperature, ambient heat, and how often you open the lid, but this tumbler is optimized to preserve cold beverages much longer than single-wall cups.

• Double-wall vacuum insulation reduces temperature exchange.
• Stainless steel interior resists warming and prevents flavor retention.
• Lid and straw minimize exposure to warm air between sips.

Is the lid really leak-resistant and easy to drink from?

The travel tumbler comes with a press-in, leak-resistant lid paired with a soft, flexible straw for comfortable sipping. The lid seals to help prevent spills while the straw is gentle on teeth and bends for varied drinking angles.

• Press-in construction helps stop splashes and minor leaks.
• Flexible straw offers comfortable, adaptable sips.
• Lid disassembles for cleaning and dishwasher-safe convenience.

Will this Hydro Flask fit in my car cupholder and backpacks?

The 40 oz Travel Tumbler was shaped to be cupholder-friendly and still hold a generous amount of liquid. Its low-profile base and balanced weight make it practical for vehicle cupholders, side pockets on larger packs, and most workplace cup mounts.

• Cupholder-compatible base fits most standard vehicle holders.
• Comfortable handle for carrying or clipping into bag straps.
• Robust construction stands up to daily travel and outdoor use.

How do I keep the tumbler clean and odor-free?

Cleaning is straightforward: disassemble the straw lid from the cup and place parts on the dishwasher’s top rack or hand-wash with warm, soapy water. The pro-grade stainless steel resists lingering tastes, so you can switch beverages without worry.

• Dishwasher-safe components for quick maintenance.
• Stainless steel interior prevents flavor transfer between drinks.
• Removable straw and lid pieces enable thorough cleaning.

Who is this for? The Hydro Flask 40 oz Travel Tumbler in Seacliff suits anyone who wants fewer refills, reliable cold retention, and a portable, easy-to-use drink system. It’s ideal for commuters, parents, athletes, outdoor adventurers, and office workers who prefer a large-capacity bottle that fits cupholders and stays fresh between refills.
