Let’s be real: everyone uses a water bottle. Whether it's for the gym, the office, road trips, or just making sure we drink something other than coffee—reusable bottles are a daily essential. And that makes them a perfect canvas for your brand. 

Now imagine this: a single co-branded water bottle gets you over 1,400 impressions per dollar. That’s some serious marketing mileage—if you pick one that people are excited to use.  

Oh, and the planet? Yeah, it appreciates it too. Americans toss over 60 million single-use plastic bottles every day. Swapping in reusables isn’t just smart—it’s necessary. 

So whether you’re sourcing swag for your team, customers, or an event, we’ve picked the best bottles that actually get used, loved, and carried everywhere. These are the tried and tested water bottles we reach for again and again.  

Water bottles come in all shapes, sizes, and degrees of insulation, so it’s fitting that their lids come in an array of options too. Depending on how you want to hydrate, there’s a lid option for you. Take the chug lid, for example—it’s built for speed. With a wide mouth opening and a cap that flips or screws off, it’s perfect for those moments when you’re parched after a workout or trying to get your daily water intake in a hurry.

Then there’s the sipper lid, which is all about control and convenience. These usually have a smaller spout or built-in straw, making it easy to take tidy sips without spilling—ideal for work desks, car cup holders, or gym machines. They’re great for casual sipping throughout the day.

Lastly, the open mouth design keeps it classic and simple: just a wide opening with no frills. It’s easy to fill with ice, clean, and drink from (as long as you’re stationary). But without a special lid, it’s not exactly travel-friendly—unless you’re cool with a few surprise water spills. Each lid has its own personality, and choosing one really depends on how, when, and where you like to hydrate.

Water bottles can come in an assortment of material, the most common being glass, acrylic, plastic, aluminum, and stainless steel. For this Kotis Picks article, we decided to focus only on stainless steel. Why?

Stainless steel is the most cost-effective option when looking at the main aspects of a water bottle: durability and keeping your drink at the desired temperature. The rest of the options, while cheaper in cost, are also weaker in performance. We want your merch to generate excitement and use, which is why we’re here to help you find the best bottle for your needs.

When it comes to insulated water bottles, not all walls are created equal. Single wall bottles are the lightweights of the bunch—great for on-the-go sipping, but don’t expect them to keep your drink cold (or hot) for long.

Step it up a notch and you’ve got double wall air-insulated bottles, which add a second layer with air in between. It’s like a puffer jacket for your drink—better than nothing but still lets some temperature sneak through.

Now enter the game-changer: double wall vacuum insulation. By sucking the air out between the layers, these bottles drastically slow down heat transfer, keeping your coffee hot and your water ice-cold for hours.

And if you’re looking for the VIP of temperature control, vacuum insulation with copper lining adds a reflective copper layer that bounces heat away like a thermal superhero. It’s the ultimate combo of science and style—your beverage’s best friend. Many of our crowned winners come with this insulation option!

Water bottles have come a long way from being just a practical way to carry water! Water bottle brands became a statement largely due to a mix of style, sustainability, and social media. As people started moving away from single-use plastics and leaning into eco-conscious living, reusable bottles became a symbol of that shift. Brands like Hydro Flask, Stanley, and S’well didn’t just sell bottles—they sold a lifestyle. With sleek designs, fun colors, and customization options, they turned something functional into something fashionable. Suddenly, your water bottle said something about your vibe: minimalist, sporty, trendy, eco-warrior… or all the above.

Social media played a huge role too. Influencers, TikTok trends, and “what’s in my bag” videos started featuring certain bottles almost like accessories—just like a cute phone case or a cool pair of sneakers. Limited edition drops and viral colors (looking at you, Stanley tumbler in “rose quartz”) only added to the hype. So now, carrying a certain brand of water bottle isn’t just about hydration—it’s kind of a subtle flex.
