Best Thermoses of 2026

"I use this water bottle every day, and it has definitely become my favorite. The insulation keeps my water cold for hours and I love the flexibility of the FreeSip lid—I can drink through the straw or tip it back, depending on the situation. It’s sturdy, leak-free, and easy to carry or clean. Plus, the color is stylish and stands out in a subtle way. This bottle combines both function and style in one reliable package."

"After trying several big-name water bottles, I finally picked up an Owala and I’m honestly impressed. As a college student, the one-handed opening, leak-proof seal, and the choice between sipping or chugging are perfect for my routine. It fits well in my backpack, and the FreeSip design is super convenient whether I’m studying or at the gym. While I use other bottles for hot drinks, this is now my go-to for daily hydration—no leaks, no hassle."

"I got the 40 oz Owala for my wife and she absolutely loves it. The standout is the FreeSip lid, which makes it so convenient to switch between sipping and chugging. The bottle holds a lot without feeling huge and keeps drinks cold all day. The Candy Store color looks great and the build is sturdy. The only tiny issue is a small scratch from tossing it in a bag, but that doesn’t impact how well it works or how much we enjoy using it."

"I'm so impressed with this pitcher! The insulation keeps drinks ice cold, and the sleek design fits perfectly in my daughter's school bag.

"I bought the purple bottle for myself and my daughters loved it so much, I had to get three more for them to take to school.

These bottles are now our family's go-to!"

"I needed a smaller, more portable bottle than my Stanley and didn’t want to splurge on an Owala. I found the Ello bottle and I’m glad I did. The color combos are cuter than most, it’s easy to drink from, and I love refilling without fully opening the lid. The handle is comfortable and it doesn’t leak when tilted. My only gripe is the lid button is a bit stiff, but overall, it’s a great, affordable, and functional option for on-the-go."

Honestly, it’s the best bottle I’ve owned and feels like it’ll last forever."

"I wanted a bottle that would keep my water cold all day at work, and the Ello delivers—ice water in the morning stays cold until 5pm. The pop-up straw is handy once you get used to it, and it’s easy to use with one hand. The stainless steel is solid, it’s survived a few drops, and cleaning is a breeze thanks to the wide mouth and dishwasher-safe design. The straw can be a bit noisy and replacements are pricey, but overall, it’s a reliable everyday bottle that I’d buy again."
