Best water bottles 2025: Top-quality reusable bottles to keep you hydrated

Whether you love a challenging hike, hot HIIT session or heavy weights workout, the best water bottles can help you stay hydrated.

Plus, having a reusable water bottle you like can encourage you to drink more water, and helps to reduce single use plastic. The best water bottles are durable, leak-proof and available in multiple shapes and sizes.

“Many of us have several water bottles gathering dust in our kitchen cupboards. Pick a water bottle that meets your needs, and you enjoy drinking from, and you’ll have a much better chance of staying hydrated,” Elliot Hansoon, personal trainer and founder of EH Coaching, told Live Science.

Around 60 percent of the body is made up of water and it plays a crucial role in every bodily function - delivering nutrients to cells, aiding digestion, helping us maintain a healthy temperature and keeping joints well lubricated and mobile.

It’s important to stay hydrated both before, during and after exercise as it helps the body function properly. When we exercise we lose a lot of fluid, and this needs topping up to avoid dehydration. Drinking water post-workout can help reduce the risk of Delayed Onset Muscle Soreness, aka DOMS.

Our testers at Live Science have rigorously tested some of the best water bottles on the market, looking at price, size, insulation, drinking spout design and if they are leakproof. Choose a bottle you like and you are more likely to keep your hydration levels up. Read on to find out about our pick of the best water bottles.

The best water bottle we've tried

YETI has a rep for making robust quality products that are high performing and built for everyday use. We’re pleased to say this is no exception with the YETI Rambler 26 oz. bottle with chug cap. Made from stainless steel, the double walled vacuum bottle is designed to keep drinks hot or cold.

It comes with a screw lid and carry handle, and a chug cap – or drinking spout – that has a steady water flow. We like that the lids are all interchangeable among the other Rambler bottles, that range in size from 12 to 64 ounces. It is also dishwasher-friendly, which seems to be a rarity when it comes to insulated water bottles. The Rambler’s wide mouth also means it is really easy to wash by hand, or put ice cubes into without having to crush them up first.

It’s slightly heavier and bulkier than your average water bottle, compared with other hiking style ones, and it’s not cheap ($99 / £99), but if you want something that looks as good as it performs, then this is a great choice.

Best water bottle for gym goers

The Takeya Actives Insulated Bottle not only looks good and boasts a sweat-free grip that makes it perfect for gym use, the double-wall design of this 18/8 stainless steel bottle will keep your drink cold throughout a workout and beyond (24 hours in fact).

It's slightly heavier than some similarly designed bottles, but has a wide handle that makes it comfortable to carry.

A removable color-coordinated silicone base is included (not standard with all water bottles) that will protect the bottle from bumps and dents and help keep it in place when sat in cup holders or on treadmill trays.

The bottle's lid is also insulated meaning moisture won't collect around the narrow drinking spout and a great addition is a lid hinge lock which prevents it from flapping back and hitting you on the nose when drinking. Unscrew the lid and the wide mouth allows for easy cleaning or adding ice. You don't need to hand wash this bottle either as it's suitable for cleaning on the top rack of the dishwasher

If 18oz capacity isn't large enough, there are other sizes to suit your hydration needs, including 24oz, 32oz, 40oz and 64oz.

Best water bottle for walkers

The popular Hydro Flask Standard Mouth is the ideal companion when heading out on hikes and this larger-sized bottle will keep you hydrated during the day with water that stays ice cold for up to 24 hours.

The bottle is made from durable 18/8 stainless steel with a powder-coated outer that resists condensation, meaning the sides of the bottle will stay dry to touch. Honeycomb insulation controls the temperature of the BPA-free lid, meaning this will remain cool, too.

The bottle comes with a standard Flex Cap that you unscrew to drink, but if you don't enjoy swigging from a water bottle's mouth, you can buy Hydro Flask's Sip Lid or Straw Lid Cap which enables you to hydrate one-handed. What's more, you can build a bespoke bottle by choosing different coloured parts and customising it with text and graphics.

Best water bottle for cyclists

If you're a keen cyclist this may be the option for you.

The beauty of the Camelbak Podium Chill Water Bottle is that it's designed to fit in most bike bottle cages preventing rattles or ejections when out riding. It will also keep your drink cooler than other bike bottles thanks to its double-walled construction.

The flow spout is comfortable in the mouth, although you will need to squeeze both sides of the bottle to get the fluid out. When we just tried to suck, it was quite tricky. The self-sealing design of the valve prevents leaks or spills even without locking the nozzle – we shook the bottle for 30 seconds and didn't detect any spillage. However, there isn't a protective cap to protect against dirt or dust collecting around the mouthpiece but you can purchase a mud cap as an add-on if needed. Another draw is that the bottle can't hold a great amount of liquid, so, if like our tester, you're someone who tends to get quite thirsty, you might want to invest in a larger bottle.

The Camelbak Podium Chill comes apart for easy cleaning and it's fine to put this bottle in the dishwasher, provided it isn't at the highest temperature setting.

Best water bottle for purity

Reusable bottles rely on us filling them with tap water.

However, this may not always taste to your liking, but with the easy-to-carry Brita Active Water Filter Bottle you can have fresh, pure-tasting water on the move thanks to its built-in filtration system.

The bottle has a replaceable carbon filter microdisk that removes chlorine and impurities from water while retaining calcium and magnesium so that you still get the health benefits of these minerals. One disk comes in the box and depending on your daily water consumption, it should last you around four weeks before it needs replacing.

There's a cap that protects the mouthpiece from dirt, although it's worth noting that this is fully detachable so there's a risk of it getting lost. The easy-grip bottle comes apart and can be put in the dishwasher, making it simple to clean after use.

We found that the Brita Active Water Filter Bottle cap can be stored on the bottom of the bottle when needed and can also be used as a cup, which makes it handy if you have kids or even pets that might need a drink on the go.

Best water bottle for adding flavors

If you don't like drinking plain tap water, the Welly Traveler Infusing Water Bottle will appeal.

Made from 18/8 stainless steel, natural bamboo, silicone and BPA-free plastic, this option also includes a removable infuser so you can naturally flavor water with fruit or herbs.

Drinks are kept cool for up to 24 hours thanks to triple-walled vacuum insulation and the bottle's sweat-free exterior stops it from slipping out of your hands. A loop cap that unscrews comes as standard or there's the option to buy an insulated flip cap if that's your preferred lid for drinking.

There's an aesthetically-pleasing range of bottle designs to choose from including terrazzo and leopard print and it's also available in 12 oz and 28 oz sizes. Plus, your purchase will support a good cause with Welly donating 1% of bottle sales to clean water projects around the world.

Best large water bottle

If you're looking for a durable plastic bottle to use every day, the Camelbak Eddy+ is a great value option.

It's made from 50% recycled material that fights against odors and stains which are common bugbears when using a plastic bottle, plus there are six colors to choose from.

The Eddy+ holds 32oz of water that's delivered through a drink straw that you flip up and bite to release liquid. The straw's value is designed to prevent leaks when closed and spills when open but does need a strong bite to get a satisfying drink.

The only downside of this larger-sized bottle is that it's too big to fit in standard cup holders. If this is a dealbreaker, you may want to go for one the smaller sizes in Camelbak's range of Eddy bottles.

We found that for longer hikes, the Camelbak Eddy is a great size to keep you hydrated and can fit easily into a stretchy backpack bottle holder. The bite-to-drink feature is also useful when on the go, as it saves losing water to leaks.

Best stainless steel water bottle

S'well is the 'original' stainless steel bottle and this non-toxic, non-leaching and BPA free reusable is a bestseller for good reason.

With a stylish design (that's been frequently copied) it's available in an array of eye-catching colours and prints and three standard sizes of 9 oz, 17 oz and 25 oz. But that's not all. The S’well bottle boasts tripled-layered vacuum-insulating technology with this largest size keeping your drink cold for an impressive 48 hours, all while remaining moisture-free on the exterior.

It comes with a standard screw cap meaning you have to stop to take a sip, but the wide mouth is comfortable to drink from and also large enough to drop in ice cubes. To customise your bottle there's the option to buy accessories such as a sports cap for one-handed drinking, or a soft silicone handle for a more comfortable carry.

The one downside of this popular pick is that it isn't suitable for the dishwasher, but you may be willing to overlook the hassle of hand washing this for a high-performing bottle that doubles up as an attractive accessory too.

Best water bottle for durability

The Klean Kanteen Classic is a popular water bottle choice.

This is mainly because it can withstand the demands of an active lifestyle as well as being lightweight even when full.

The chip-resistant coating protects against bumps and bashes, so is great for outdoor activities and although this bottle isn't insulated, ice can be added to the 1.75 inch opening by unscrewing the lid. A narrow profile means it fits in most cup holders in cars and on exercise machines and strollers.

There are 10 colors/designs and four sizes in total to choose from and it comes with a sports cap with flow mouthpiece that can be removed for easy cleaning. Other compatible caps available to buy include a carry loop cap and a sippy cup cap for kids.

Best water bottle for portability

​​The Thermos Intak Bottle – also known as the Thermos Hydration Bottle, is a great value option for the gym or your commute to work and can be tossed in a bag without the worry of spillages.

The leak-proof lid opens with the press of a button and for peace of mind there's the addition of a locking ring mechanism to prevent it popping off in a bag. A narrow spout means drinking from it while walking isn't a problem and the whole lid screws off so you can easily add ice or fruit to your water.

If you need prompting to drink more water, there are handy volume markings on the side of the bottle and the lid has a dial tracker so you can monitor your intake. Although there's a good range of colors to choose from, a possible downside is that this water bottle only comes in one size. However, most people will find that the 24 oz capacity is more than enough to stay hydrated on-the-go until the next refill.

Best large-capacity water bottle

If you have serious hydration goals, the Aquafit 1 Gallon Water Bottle is the bottle to help you reach them.

This large capacity vessel holds 128 oz of liquid so that you don't have to worry about refills and there's also a time marker on the side to track how much you drink and ensure hydration levels are topped up from morning 'til night.

Two lids are included, a spout lid and a straw lid, along with a carry strap. A large handle makes it easier to lift when drinking, however, this bottle is obviously very large, so we didn't find it the most convenient option for taking to the office, since it took up most of our bag! For home working, however, it was a life saver and meant we didn't have to keep getting up from our desk to refill our glass.

There are eight colors to choose from and each water bottle comes with a brush for cleaning as this bottle isn't dishwasher-friendly.

Best water bottle for purification

Dubbed ‘the world’s first self cleaning bottle’, the LARQ PureVis has a rechargeable LED in its lid that uses UV-C light to sterilize itself and kill bacteria and odor-causing germs. To activate, just press the button on the top of the list to blitz 99.99 percent of pollutants and bio-contaminants in the water, including E. coli. The bottle also self cleans every two hours.

Let’s be honest, anything that requires less cleaning is a win from me, so I’m very happy with this bottle. LARQ still recommends you give it a wash occasionally but it’s good not to have to worry about that so much.

You don’t even need to charge it that much – once a month should do it – and you can enjoy fresh tasting water without that nasty musty smell bottles that tend to develop over time. It’s more expensive than regular reusable water bottles, but if clean water is important to you, then it’s a good investment (and think of the money you’re saving on purification filters). It’s also undoubtedly the most stylish water bottle on the market today.
