Whether you're hitting the road, bike trails, or the gym, you’ll find S’well fits just right in most standard-size cup holders.
- DON’T SWEAT IT: S'well beverage containers are insulated with a copper wall layer to eliminate condensation by providing an exterior that won't sweat on your hands or in your bag.

The S’well water bottle was designed to fit into your daily routine, no matter your lifestyle. It is our second pick because the brand certainly made stainless steel more appealing for everyone with its stylish design and bright, lively hues. Unlike most other brands, S’well opted for the screw-top lid design with a wide mouth that’s large enough for modest-sized ice cubes. Yet the mouth isn’t so wide that it soaks your clothes when you take a sip.
The stainless bottle comes in three convenient sizes: 9 oz., 17 oz., and 25 oz. You will appreciate the slick, narrow design of these stainless steel bottles; it makes them effortless to fit into any bag and standard cup holders, as well as easy to carry to the work, gym, or wherever you need to hydrate.
Unlike Kool8, the mouth of this bottle is narrower and won’t fit large ice cubes. On the upside, the bottle features triple-walled vacuum insulation that could technically keep your hot drink warm for up to 18 hours and cold drinks cold up to 36 hours. The lid is leak-tight and the entire bottle is made from food-grade material.
It is versatile, too. Amazon reviewer neophyte27 says: “This thing is a necessity. I use it for three things and it is perfect in each way.” 3/12/2021
- Triple-layered vacuum insulation
- It fits most bags and cup holders
- Easy-carry slim design
- No BPA
- Not dishwasher safe
- Prone to scratches
- Quality authenticity has mixed reviews
3- Best for Exercising: Takeya Actives Insulated Water Bottle

$23.99 in stock
4 used from $21.49

Just from the name, you can tell that this stainless steel water bottle was designed for exercising. It is hands down the best stainless steel water bottle for the gym – it brings together the spill-free sips thanks to the spout lid and breezy cleaning and refilling because of the wide-mouth design. The wide loop on the lid is a handy tool for carrying the bottle, plus the spout is insulated and leak-proof.
If you’re tired of water vapor clouding the lid and your water bottle, you will be glad that both are condensation-free and sport double-walled insulation. Owners note that the bottle works equally well for hot and cold drinks, keeping them in desired condition for more than 12 hours.
If you’re looking for a hydration accessory to take to the yoga studio, this is a good find. It features a detachable silicone bumper that keeps dents and scrapes at bay, while allowing you to set it down quietly on the mat or floor. Trust us; you won’t disrupt anyone’s zen or meditation while doing yoga.
The bottle is pricier than most of our other picks, although it offers a large capacity of 64 fluid ounces. There are 18-ounce, 24-ounce, 30-ounce, and 40-ounce options, as well. The only notable downside is that it feels a little bulkier and may be prone to mold if not allowed to dry out well.
- Wide mouth for easy upkeep and refilling
- Both spout lid and bottle double-walled insulated
- Leak-free spout lid
- Design susceptible to mold
- The design is a bit bulky
- Pricier than comparable brands
4- Best Budget Option: FineDine Triple Insulated Stainless Steel Water Bottle

$19.49 in stock
- DOUBLE WALL - This bottle is crafted with double walls, the only bottle out there with inside and outside stainless steel. Beverage will be kept hot for up to 12 hours and cold for up to 24! The double-wall feature prevents condensation and burns, retaining the temperature of your beverage.
- DURABLE and UNBREAKABLE – Our lightweight yet rugged metal water bottle is crafted of 18/8 eco-friendly premium stainless steel. Completely shatterproof, it replaces those impossibly fragile glass bottles for glass-free zones and child-attended events. In addition, it’s odor, smudge, and rust resistant.
- SWEATPROOF - Condensation never appears on the steel bottle, ensuring a secure grip, dry fingers, and no need for a coaster. These reusable bottles are great for hiking, biking, gym, travel, school, work, and just about anywhere you might get thirsty!
- ERGONOMICALLY DESIGNED - A 1¼”-diameter mouth accommodates small ice cubes and chopped fruit. Its slim, sleek body fits in standard cup holders, making the hiking bottles convenient for taking on the go. The screw-top lid is entirely leak-free to prevent spills and messes.
- GREAT GIFT - This set would make a great Christmas, holiday, or special occasion gift for an active person in your life. Set of 2, capacity of 17 oz. A flat, stabilized bottom keeps the reusable bottles flush on table and countertops. Please note: bottles are not dishwasher safe.
Don’t be fooled by the price of the FineDine stainless steel water bottle into assuming that the unit is second-rate. This water bottle sure packs a punch, keeping your drinks refreshingly cold for up to 24 hours or hot up to a half a day. That’s all thanks to its triple insulation, which helps maintain the temperature of your drinks while preventing any cold injuries or burns.
Amazon reviewer Herman F Richardson Jr gives it a perfect 5 out of 5, commenting: “Well-insulated and leak-proof.” 4/12/2021.
What we love about this bottle is that it features a stainless steel construction from inside out, making it durable, lightweight, and exceptionally resistant to rust, odors, and smudges. Best of all, you will get two bottles for a market-beating price (in fact, the pack costs nearly half of the going price of the closest competitor).
Made for grab-and-go drinking, the stainless steel water bottle is ideal for camping, traveling, hiking, and commuting between your home, office, and the gym. It feels like a soda bottle in your hand, and is best for morning java, tea, fruit juices, and, of course, water.
Surprisingly, the mouth of these flasks is wide enough to insert fruit slices and ice cubes into the bottle. The screw-top lid is also fully insulated, but it can be difficult to undo. I guess that’s the price you’ll pay for a premium level of insulation.
The FineDine stainless steel water bottles come in 17-ounce capacity, which isn’t common on the market. Their distinct sleek designs allow them to slide into any bag and fit in any standard cup holder. However, both the bottles and their lids aren’t dishwasher safe.
- Drinks stay hot or cold for up to 12+ or 24+ hours
- Fits most bags and cup holders
- Competitive price for a two-pack (best value of the bunch)
- Entire bottle not dishwasher safe
- The lid can be hard to unscrew
5- Best Versatile: IRON °FLASK Stainless Steel Insulated Sports Water Bottle
IRON °FLASK Sports Water Bottle - 32 Oz, 3 Lids (Straw Lid), Leak Proof, Vacuum Insulated Stainless Steel, Hot Cold, Double Walled, Thermo Mug, Standard Metal Canteen
- INSULATED SPORTS WATER BOTTLE: Goodbye sweat! The narrow mouth double wall insulation makes the Iron Flask sweat-free! It keeps your drink COLD for up to 24 hours, and HOT for up to 12 hours. *NOTE: ONLY the 12 Oz, 16 Oz, 20 Oz & 24 Oz fit in cupholders*
- VERSATILE 3-LID DESIGN: The Iron Flask boasts a trio of 100% leak-proof lids – the patented Straw Lid for easy sipping, the convenient Flip Lid, and the carry-friendly Handle Lid. Tailor your hydration experience for any activity!
- 18/8 PREMIUM STAINLESS STEEL: The Iron Flask is made of 18/8 Stainless steel that is 100% BPA free and non-toxic. It will never leave a metal taste or rust. HAND WASH ONLY WITH SOAPY HOT WATER!
- FUNCTIONAL DESIGN: The powder coat exterior finish is a classic. It assures that you stand out with a very durable and elegant bottle. Our logo is now LASER ENGRAVED to assure the highest quality as well.
- 100% SATISFACTION GUARANTEED: We guarantee that the high quality Iron Flask bottle will surely please you! If, for any reason, you are not 100% satisfied with the Iron Flask, we will issue you a full refund or an exchange!
The Iron Flask was a no-brainer choice given its versatility. Although it is almost similar to our other top picks in functionality and overall design, the real differentiator comes in the form of lid options. We were thoroughly impressed by the choice of three different lids: a standard stainless steel lid, a flip lid, or an innovative option with a built-in straw.
As with Kool8 and FineDine bottles, this one also can keep your beverages hot for up to 12 hours and cold drinks cool for up to an entire day. Amazon reviewer Jessica R : “I’ve put ice water in it and had it still be very cold the next day.” But it tends to lag a bit in terms of quality of the stainless steel and finishing touches.
The highlight of the bottle is the lid that comes complete with an in-built straw for easy sipping of your drinks. Of course, you can swap it out for the flip lid or the traditional stainless steel lid. That’s definitely something to keep in mind when doing comparable shopping for your next stainless steel water bottle, as most competitors offer additional lids as side upgrades that can hike the price.
You can tell by the name that it’s designed for sports but it comes in six different sizes, including 12, 16, 20, 24, 32, and 64 ounces, meaning that there’s an option for pretty much any lifestyle. However, the larger sizes are heavy when filled and won’t fit in the standard cup holders.
- Three different lids included
- Double-walled vacuum-insulated
- Comes in 19 fantastic colors
- Larger-capacity options are bulky and heavy
- Some parts are hand-wash only
Buying Guide for the Best Stainless Steel Bottles
First Up — Why Opt for a Stainless Steel Water Bottle?
You have probably wondered what the best material for a reusable water bottle is. For many people, the answer to that question is stainless steel, and it’s easy to understand why. Let’s shed some light on some of the advantages of using a water bottle constructed of this state-of-the-art metal.
– Stainless steel bottles keep drinks cooler or warmer for longer
The strength and malleability of stainless steel allow water bottle manufacturers to create airtight, vacuum-insulated designs. As a result, a well-built stainless steel bottle can keep your beverages and drinks steaming hot or crispy cold for long, unless you leave yours out in the sun.
– Stainless steel is good for you and our planet
Let’s get one thing straight right off the bat: the majority of water bottles on the market right now are made from plastic, primarily because it is a cheap material. But it’s bad news for pretty much everyone.
It’s bad for you, as some plastic bottles contain BPA and other horrible chemicals that could leach into your drinking water and potentially cause harm to your health.
Plastics aren’t ideal for the environment, either. It is no secret that most plastic bottles can take as long as a millennium to biodegrade, and, what’s worse, more and more of them are ending up in our oceans, rivers, and lakes. They are literally strangling the life out of our water bodies and marine life, so buying a plastic option is a big no-no for any honest-living eco-warrior like you and me.
With a stainless bottle, that’s a thing of the past. It allows you to stay properly hydrated without harming the environment. As such, if you want to limit your use of plastic, save the planet for its devastating effects, and reduce your carbon footprint, you will appreciate stainless steel as a water bottle material.
Stainless steel water bottles are not only highly recyclable but they are also overall more eco-friendly than those made from plastic. Even more encouraging, the metallic material is naturally free of bisphenol-A, meaning that you won’t have to worry about BPA leaching into your drinks.
– The material is food-grade and versatile
If you’d like to use your bottle beyond holding drinking water, a stainless steel option is right up your alley. The material is food-grade, non-reactive, and doesn’t shed chemicals. For that reason, you can use it to keep any type of food and drinks hot or cold, ranging from hot soups to fruit juices.
– Stainless steel water bottles are stylish, too!
As a fitness enthusiast who cares about the environment, I try my best to drink plenty of fluids and lower my eco-footprint as much as possible. And one of the most effective ways to do so is to invest in a quality, reusable water bottle made from a planet-friendly material.
That’s good and all, but a stylish one that I love lugging around with me and will keep my water crisp all day and hot beverages steaming hot for hours? Where can I sign up, right? That is exactly what you get from a stainless steel water bottle.
The majority of these bottles come in a dashing selection of fashionable style and colors, making it easy to pick one that suits your personality and taste in fashion.
– Durability at its best
Stainless steel water bottles are typically solidly-made and quite durable, lasting years and years if you care well for them. That’s especially so because they are usually crafted from one unified piece of metal, reducing the chances of cracks, leakages, and other flaws that could threaten their integrity.
What to Look for in a Stainless Steel Water Bottle
If you have the right kind of water bottle, committing to your hydration life becomes so much easier and more hassle-free. You don’t want a bottle that’ll feel like a chore or inconvenience in your lifestyle. What you need is a stainless steel bottle that matches your needs and personality.
But that isn’t all. How do you ensure you are choosing the perfect vessel to keep your good old H2O or beverages? Here are some key considerations we accounted for when zeroing in our top picks.
Consideration #1: Your Style
Staying hydrated doesn’t have to come in the way of your lifestyle and sense of style. And considering that stainless steel water bottles come in all sorts of colors, designs, and shapes, it is important to opt for one that will fit perfectly with your personality and style.
For example, if you consider yourself to be trendsetter, you can get several bottles in statement-making hues to help match, compliment, or finish off your outfits in a stylish yet practical manner. Stainless steel in and of itself feels and looks vibrant, fashionable, and versatile sartorially, so you can stay on top of both your styling and hydration game.
Consideration #2: Mouth Design
Whether you prefer a bottle with a narrow or wide mouth is a matter of personal preference. However, if you want a water bottle that you refill in a jiffy or add ice to your drinks, then you should definitely go for a wide-mouth design.
Meanwhile, if you plan to take sips of water while jogging, running, or walking briskly, you’d want to stick with a narrow-mouth option. That’s because water may rush out of the bottle faster if the mouth is wide, leading to embarrassing and inconvenient spills while you’re hydrating.
Consideration #3: Filter vs. No Filter
If your city tap water has too much chlorine or does not taste downright great, you’ll want to score a bottle fitted with a filtration system. The filter will help clean your drinking water and rid it of silt, sediments, and some toxins, which can come in handy if you tend to refill at water stations, fountains, or natural springs of questionable integrity.
The filtration feature can dramatically improve the quality and taste of your water, so you can hydrate with confidence. On the flip side, stainless steel bottles equipped with filters tend to be pricey. As such, if you’re confident in the quality of your refilling stations or you already own a water filtration system at your home or office, it won’t hurt to skip this feature.
Also, note that not all filters are created equal. Is it a filter straw, absorption filter, or a mechanical filter? The more advanced the filter system, the more likely you will enjoy the drinking experience.
Consideration #4: Color
Majority of stainless steel water bottles we reviewed — particularly our top recommendations — are sold in a variety of designs, colors, and shades. You can pick anything from classic metallic black to a bold pink design. It’s all about your personal preference – snag one in your favorite color to add a dose of elegance, style, and oomph to your lifestyle.
Remember, some colors are more likely to show dirt, sweat marks, and streaks than others. Whatever the case, the last thing you want to choose is a color that you will get tired of quickly. Stick to your classic, evergreen hues, especially those that marry well with your favorite outfits.
Consideration #5: Insulation
There’s no point in purchasing a stainless steel bottle without any kind of insulation. Accordingly, all our picks feature a double-walled vacuum insulation as the gold standard. This type of airtight insulation is designed to keep hot drinks hot and cold drinks cold for pretty much the whole day.
If you’re into hiking, running, cycling, jogging, or reside in an area with a hot climate, it’s a no-brainer to choose a stainless steel bottle with leak-proof insulation. Well, who would want to take a sip of tepid or warm water on a scorching hot day?
Consideration #6: Lifestyle and Intended Use
We’re going to reiterate that you should choose a water bottle that goes perfectly well with your lifestyle and everyday hydration needs – all the more so if you’ve an active lifestyle. For instance, if you are looking for a gym-perfect or biking-friendly bottle, drill down your choice to ones equipped with a sports cap.
Similarly, if you are a hiking enthusiast, a bottle with a clip will help you attach it to a karabiner and power through your hikes without any fuss.
Consideration #7: Capacity and Size
Perhaps the most crucial factor to keep in mind is the capacity of the water bottle. Consider both the internal water-holding capacity and the external size of your candidate bottle.
As for external size, it pays to ensure your potential stainless steel water bottle will fit wherever you need it to. Do you want it to fit inside your car’s cup holder? Will you be toting your water bottle in a purse or small tote bag? Be sure to check the overall dimensions to ensure it’ll fit properly, and thankfully, most brands include the info about the fit and size on the product description and packaging.
When it comes to internal capacity, your choice is endless, ranging from compact 8-, 9-, or 12-ounce options that can hold roughly a standard glass of water to 64- or 84-ounce giants holding beyond your recommended daily intake of dietary fluid. The trade-off comes in the form of heft, though.
While a high-capacity bottle means less frequent refills, you will be lugging around a bulkier, heavier unit.
Consideration #8: Design and Extra Features
An elegantly-designed bottle is good and all, but it pays to opt for a design that’s low maintenance and reasonably easy to clean. Take a closer look at the mouth and nozzle design. The last thing you want is a poorly-designed nozzle that will either spill drinks or harbor unsightly gunk or germs.
Some designs incorporate clever and useful additional features that may appeal to you. For instance, a bottle like Kool8 has a tea infuser, allowing you to make a flavorful brew on the go. Other models feature fruit infusers that allow incorporating fresh fruit into your drinks.
Also, check for bottles with easy-open designs if you plan to sip while working out or exercising. Those that open with a press of a button are ideal for people with a poor range of motion or grip.
