Hydro Flask Travel Tumbler 40 oz Sandpiper – Insulated Stainless Steel with Handle & Straw Lid, TempShield Cold Retention

Hydro Flask's 40 oz Travel Tumbler in Sandpiper is an insulated stainless-steel cup with a sturdy handle, press-in straw lid, and TempShield insulation to keep cold drinks cold for hours.

This 40-ounce Travel Tumbler blends a high-capacity reservoir with a comfortable ergonomic handle and a flexible straw lid so you can sip on the go without constant refills. Built from pro-grade stainless steel and Hydro Flask's TempShield double-wall vacuum insulation, the tumbler resists flavor transfer and fits most vehicle cupholders—making it a reliable everyday water carrier for sport, commute, and leisure.

How well does this tumbler keep drinks cold?

The TempShield double-wall vacuum insulation minimizes temperature transfer so chilled beverages stay noticeably colder for extended periods. Because the design limits condensation, it also keeps hands and surfaces dry.

• TempShield double-wall vacuum insulation preserves cold temperatures for hours
• Insulated walls reduce condensation on the exterior
• Durable stainless steel resists heat transfer and flavor retention

Is the lid leak- and spill-resistant for travel?

The press-in flexible straw lid is designed to be splash- and leak-resistant when seated correctly, enabling easy sipping while reducing accidental drips. The soft straw bends for comfort and is gentle on teeth, while the press-fit design stays secure during normal movement.

• Leak-resistant press-in lid with flexible straw for comfortable sipping
• Straw lid is soft and easy to flex for angled sipping
• Not a fully sealed, screw-top leakproof; avoid tipping upside-down in extreme conditions

Will this cup fit in my car or gym cupholder?

The tumbler's base is shaped to accommodate most standard cupholders so it rides securely in cars, strollers, and gym equipment. The ergonomic handle does not interfere with placement in many holders, and the 40 oz size balances capacity with compatibility.

• Cupholder-friendly design fits most vehicle and equipment cupholders
• Ergonomic handle located for comfortable carrying without blocking placement
• 40 oz capacity reduces refills while remaining practical for daily use

How do I clean and maintain the Travel Tumbler?

Hydro Flask recommends disassembling the straw lid and placing components on the dishwasher's top rack for convenient cleaning. Stainless steel construction resists odor and flavor retention, and handwashing the lid parts can extend seal life.

• Dishwasher-safe when disassembled; place smaller parts on the top rack
• Stainless steel interior resists odors and flavor transfer
• Not suitable for microwaves, stovetops, or freezers; keep hot liquids away from children

Who is this for: The 40 oz Hydro Flask Travel Tumbler with handle is ideal for commuters, athletes, parents on the go, and anyone who wants a high-capacity, low-maintenance cold cup. It suits users who value durable stainless steel, easy sipping with a flexible straw, and a carry-ready handle for sidelines, travel, and daily hydration without repeated refills.
