Hydro Flask Travel Tumbler 40 oz Trillium – Insulated Stainless Steel with Handle & Straw

The Hydro Flask 40 oz Travel Tumbler is a double-wall insulated stainless-steel bottle with a sturdy handle and flexible straw lid designed to keep drinks cold and easy to sip on the go.

This Travel Tumbler blends high-performance insulation with practical features so you refill less and drink more. Built from pro-grade stainless steel and finished in vibrant colors, it balances large capacity with a cupholder-friendly shape. The press-in lid with a soft straw is engineered for comfortable sipping, while the robust handle makes carrying or clipping the bottle effortless during daily routines, commutes, or outdoor trips.

How long will the tumbler keep beverages cold?

The Hydro Flask uses double-wall vacuum insulation to slow heat transfer, meaning cold drinks remain noticeably chilled for hours. While exact duration varies by initial temperature and ambient conditions, the TempShield design preserves cold temperatures far longer than single-wall bottles.

• Double-wall vacuum insulation for extended cold retention
• Large 40 oz capacity reduces the need for frequent refills
• Stainless-steel construction minimizes heat gain from outside

Is the lid leak-resistant and easy to sip from?

The tumbler comes with a press-in, leak-resistant lid fitted with a flexible straw that’s gentle on teeth and easy to angle while drinking. The lid seals securely for everyday use, and the straw lets you sip without tilting the bottle excessively.

• Press-in lid designed to limit spills during normal use
• Flexible straw for comfortable, multi-angle sipping
• Removable components for quick cleaning and sanitation

Will this fit in my car’s cupholder and carry easily?

Hydro Flask designed the 40 oz Travel Tumbler with a tapered base to fit most cupholders while still offering a generous water volume. The molded, durable handle adds secure carrying and makes it simple to grab when you’re moving between errands or loading into a bag.

• Cupholder-friendly profile for car, stroller, and bike mounts
• Comfortable, strong handle for one-handed carrying
• Balanced weight distribution even when full

How do I clean and maintain the tumbler?

The Travel Tumbler separates into a few simple parts: the cup, the straw, and the lid components, which are all dishwasher-safe for convenient cleaning. Routine washing prevents flavor transfer and keeps the exterior finish bright over time.

• Disassemble straw lid before placing in the dishwasher
• Stainless steel interior resists odor and flavor retention
• Handwashing recommended for longevity of exterior finishes

Who is this for: The Hydro Flask 40 oz Travel Tumbler is ideal for commuters, outdoor enthusiasts, parents, and anyone who wants large-volume cold hydration without frequent refills. It suits people who value durable construction, easy sipping on the move, and a design that fits cupholders and travel gear. If you prefer a big-capacity bottle that combines dependable insulation, a comfortable handle, and a leak-resistant straw lid, this tumbler delivers practical everyday performance.
