Hilary Duff has been spotted using the Owala FreeSip while performing, and its leakproof design, built-in straw and cold-retaining insulation explain its everyday appeal.
The Water Bottle Hilary Duff Takes on Tour
August 26, 2026 – Staying hydrated during a long performance requires a bottle that can keep up. Hilary Duff has been spotted using the Owala FreeSip 32-Ounce Water Bottle on stage, bringing one of the most recognizable reusable bottles into her busy routine.
The appeal is not hard to understand. The FreeSip combines a built-in straw with a wide-mouth drinking opening, allowing you to either sip upright or tilt the bottle back for a larger drink. Its insulated stainless-steel construction is designed to keep beverages cold for up to 24 hours.
For anyone who carries a water bottle through work, workouts, travel or errands, that combination of convenience and insulation can make it easier to keep water nearby throughout the day.

The FreeSip Lid Is What Makes It Different
The defining feature is the FreeSip spout. Instead of choosing between a traditional straw bottle and a wide-mouth bottle, you get both options in the same lid.
The built-in straw lets you drink without tipping the bottle, while the larger opening allows you to drink directly from the spout when you want more water at once. The lid opens with a push-button mechanism and locks closed when not in use.
That design is particularly useful when you are moving around. You can take a quick sip while walking or working without having to unscrew a cap or handle a separate straw.
It Is Designed to Stay Leakproof
A reusable bottle becomes much less useful if it cannot safely go inside a bag. The FreeSip uses a locking lid designed to prevent leaks when properly closed.
The carry loop also doubles as part of the locking mechanism, giving the bottle an easy way to be transported while helping keep the top secured.
That makes the bottle useful beyond the gym. It can be carried to work, packed for travel or taken along during a long day without requiring the constant worry that water will spill into your bag.
The Stainless Steel Keeps Water Cold
The FreeSip uses insulated stainless steel with a triple-layer construction. The company says the bottle can keep drinks cold for up to 24 hours.
That feature is especially useful during summer. Filling the bottle with chilled water or ice in the morning can give you cold water well into the afternoon and evening.
The wide opening also makes adding ice easier than it is with many narrow-mouth bottles. That small detail matters if cold water is a priority rather than simply an added bonus.

There Are Multiple Sizes
The FreeSip is available in several sizes, including 24-ounce, 32-ounce and 40-ounce versions.
The 32-ounce size used in the celebrity feature offers a middle ground between capacity and portability. It holds more water than a compact bottle without being as large as the 40-ounce option.
The 24-ounce version can be more convenient for commuting because of its smaller footprint, while the larger versions are better suited to people who prefer carrying more water between refills.
The Colors Are Part of the Appeal
Function is only part of the reason the FreeSip has become so recognizable. The bottle is available in a wide range of color combinations, from subdued neutrals to much brighter shades.
That makes the bottle feel more like an accessory than a purely practical object. Choosing a color that appeals to you can also make reaching for the bottle more enjoyable, which matters when the goal is simply to drink more water throughout the day.
There are also different seasonal and retailer-exclusive color combinations, giving shoppers plenty of options beyond a single standard finish.
Shoppers Have Put It Through Its Paces
The FreeSip has attracted strong customer feedback for its durability, insulation and leak resistance. More than 11,000 five-star reviews were highlighted on REI’s site in the recent celebrity-shopping feature.
Users have particularly praised its ability to keep drinks cold and the convenience of being able to choose between the straw and wider drinking opening.
Independent testing has also found the bottle effective at preventing spills and retaining cold temperatures. One test found only a modest increase in water temperature after the bottle was left at room temperature for eight hours.

There Are a Few Practical Considerations
The larger FreeSip sizes come with one obvious tradeoff: they are bigger and heavier. The 40-ounce version, in particular, can be less convenient to transport and may not fit standard vehicle cup holders.
Cleaning also requires some attention. The lid, straw and gasket can be washed separately, but the stainless-steel body may require hand washing depending on the model and manufacturer’s care instructions. Small sealing components underneath the lid should also be removed and cleaned regularly.
For most people, those are manageable tradeoffs for a bottle designed around frequent everyday use.
Why It Works for Busy Days
The FreeSip’s biggest advantage is that it solves several small problems at once. It provides a large capacity, stays cold, offers two ways to drink, closes securely and includes a handle for carrying.
Those details become more valuable during long days. A bottle that can sit in your bag without leaking and still contain cold water hours later is useful whether you are heading to a workout, commuting, running errands or spending the day on your feet.
Duff’s use of the bottle on stage is therefore less about celebrity endorsement and more about demonstrating exactly the kind of situation where its design makes sense.
Final Thoughts
The Owala FreeSip has become popular because it combines features that are genuinely useful rather than relying on appearance alone. The two-in-one drinking spout, leakproof lid, insulated stainless-steel body and range of sizes make it a practical everyday bottle.
The 32-ounce version offers a useful balance of capacity and portability, while the smaller and larger options let you choose according to your routine. Add the wide range of colors, and it is easy to see why the bottle has become a familiar sight both on the go and on stage.
