Hilary Duff’s Go-To Accessory Is the Affordable, Trendy Water Bottle Everyone’s Obsessed With

Hilary Duff has made one accessory part of her daily uniform, and it isn’t a designer handbag or sunglasses. It’s an insulated water bottle that goes everywhere she does. Spot her leaving the gym, out with her kids or running errands around Los Angeles, and chances are she’s clutching her trusty Owala FreeSip Water Bottle.

The Lizzie McGuire star and mom of four was an early adopter of this ‘It’ accessory, first toting an Owala bottle in 2023. Since then, she’s accumulated a collection of colorways — white, orange and a cute teal-and-pink pick, which she paired with a green workout jumpsuit earlier this year. There’s even a kid-sized version in Duff’s rotation, presumably for the little ones who want to match mom.

Aside from being practical, the bottle has a number of celebrity fans — Gisele Bündchen, Margot Robbie and Jennifer Lawrence — and has quietly become one of the most popular hydration accessories in Hollywood. The reason it’s so hot is hinted in the product name: Users have two ways to drink from one spout, whether it’s the built-in straw for casual sipping (like when you’re at the office or sitting in the carpool lane) or a wider opening for guzzling (ideal for after Pilates class when you need to chug). One push-button lid does both jobs, making fumbling and swapping caps a thing of the past.

While the Freesip comes in multiple sizes, the 24-oz option hits a sweet spot, since it’s big enough to keep you hydrated through a long afternoon yet small enough to slide into a car cup holder or the pocket of a tote. The stainless steel insulation keeps water cold for hours, while the leakproof lid lets you toss it in a bag without panicking about your laptop or the paperback you’ve been meaning to finish.

The Owala’s color-blocked design is part of its charm, too. The eye-catching combinations feel a little playful, a little retro and pair surprisingly well with athleisure or a casual weekend outfit. It’s the rare functional item that actually looks cute in a photo. . . which probably explains why it keeps ending up in candid celebrity shots.

At $30, the tumbler is genuinely affordable, too, giving you that celebrity cosign, smart engineering and fun colors minus the sticker shock. The BPA and phthalate-free design is easily portable, easy to clean (the cup is hand-wash only, but the lid is dishwasher safe!) and easy to love — just ask Amazon shoppers!

“Love this,” one reviewer put simply. “Easy to clean, fits in car cup holders! Keeps fluids cold for longer then 24hrs. And it really is leak-proof.”

“I have purchased many water bottles over the years, searching for the perfect one. The Owala FreeSip is a definite winner,” another person stated, noting that they’ve owned both the 24-oz and 32-oz options. “One of my favorite features is the straw. Being able to choose between sipping and slurping was a game-changer for me. I have never had issues with the bottle leaking. It fits perfectly in my backpack pocket, and the handle makes it more convenient to carry compared to other water bottles I have had in the past. Additionally, it keeps my water ice cold all day long. I take my Owala everywhere, use it every day, and do not plan on ever buying another brand of water bottle. It’s just that good!”

There’s something refreshing about watching a celebrity champion a practical $30 item with the same enthusiasm she might show for a luxury bag. Duff’s Owala habit feels less like a paid endorsement and more like a real person who found a bottle she actually likes and stuck with it. If you’ve been on the fence about joining the FreeSip club, consider this your nudge. Pick a color that makes you smile — and maybe grab a second emergency one for the car!
