If you have any questions about what are the best water bottles – then jump to our comment section below and ask our experts.

Starting off our list with one of the best brands on the market when it comes to water bottles. The Hydro Flask Water Bottle boasts a beautiful and clean design, a top-notch construction, and delivers an amazing performance.

Once you hold this bottle, you can immediately tell it’s a high-quality product. And as such, it does come with a not so budget-friendly price, but even when you take its minor drawbacks into consideration, it’s still well worth the investment.

We’ve done all the research for you and found the best place to buy the Hydro Flask:
Where to buy:
Specs & Features:
  • Material: Stainless Steel
  • Capacity: 24 oz
  • Weight: 13.2 oz
  • Brand: Hydro Flask
What we like:
  • Well insulated
  • Leak-proof
  • Convenient handle strap
  • Nice grippy texture
  • No condensation
What we don’t like:
  • It’s not dishwasher-safe
  • It dents easily

It features the TempShield double wall insulation, which keeps your drinks icy cold for up to 24 hours or steamy hot for up to 6 hours. The inner lid features a Honeycomb Insulation that provides additional temperature control while its sturdy stainless-steel construction prevents condensation and guarantees no flavor transfer.

The Hydro Flask comes standard with the Mouth Flex Cap, which is made with stainless-steel pivots and an easy-to-carry strap. But you can also buy the Mouth Sport Cap which lets you hydrate one-handed on the go.

Also, the powder coat finish ensures durability as well as an easy-grip and a sweat-free experience. And for your peace of mind, the Hydro Flask Water Bottle is BPA-free.

Because of the massive hype that surrounds our next water bottle, we had pretty high expectations before testing it. And the truth is, it did not disappoint us at all!

We had already reviewed a cooler from YETI before, so we were aware of the brand’s high-quality materials and solid construction. And this YETI water bottle is no exception. The Rambler offers a sturdy construction, excellent ice as well as heat retention, and that sleek design all the cool kids from Instagram dig.

We’ve done all the research for you and found the best place to buy the YETI Rambler:
Where to buy:
Specs & Features:
  • Material: Stainless Steel
  • Capacity: 26 oz
  • Weight: 1.63 lbs
  • Brand: YETI
What we like:
  • Sleek design
  • Beautiful color options
  • Heavy-duty construction
  • Durable
  • Excellent insulation
What we don’t like:
  • Pricey—but worth the investment!
  • Straw cap is sold separately (considering the price, it would be nice to included)

It features a double-wall stainless-steel vacuum insulation, which works amazing at keeping cold beverages ice-cold and hot liquids piping hot all day long.

The DuraCoat Color together with its shatter-resistant construction ensure the Rambler will withstand many years of wear and tear.

This model comes standard with a Chug Cap for easy sipping, but you can also switch for the Straw Cap (at an additional cost) if that’s more your cup of tea.

The Chill water bottle features a THERMALOCK double-walled vacuum insulation, which works amazing at keeping your drinks cold all day long–but not up to 28 hours as advertised.

A couple of great features from the Contigo bottle is the flip-up cover that protects the mouthpiece against dirt and germs and the Autoseal button for easy on-the-go sipping and for preventing spillage and leakage.

We’ve done all the research for you and found the best place to buy the Contigo AUTOSEAL:
Where to buy:
Specs & Features:
  • Material: Stainless Steel
  • Capacity: 24 oz
  • Weight: 10.4 oz
  • Brand: Contigo
What we like:
  • Clean design
  • Very ergonomic
  • Well insulated
  • One-handed operation
  • Spout cover
What we don’t like:
  • It dents easily
  • Not good for hot beverages
  • The intricate lid can be rather difficult to clean

This bottle can be easily manipulated with just one hand and there’s also an integrated carrying handle for convenient transport.

However, unlike some reusable water bottles from our list, the Contigo AUTOSEAL Chill Water Bottle does not work great with hot beverages and only the top lid is dishwasher-safe.

If you’re like me and you like your water to taste as pure as it can be, then glass water bottles are the real winners. We found that the Ello Syndicate Glass Water Bottle hits all marks in terms of flavor, design, construction, and price.

Although glass water bottles are more prone to break when compared to stainless steel and plastic ones, the Ello Water Bottle has proven to be quite sturdy even after a few accidental drops and bumps. It doesn’t leave any lingering flavor or odor from previous liquids either.

We’ve done all the research for you and found the best place to buy the Ello Syndicate:
Where to buy:
Specs & Features:
  • Material: Glass & Silicone
  • Capacity: 20 oz
  • Brand: Ello
What we like:
  • Clean water flavor
  • All parts are dishwasher-safe
  • It doesn’t retain either flavor or odor from previous drinks
  • One-handed operation
  • Easy comfortable grip
What we don’t like:
  • Narrow opening for ice cubes

It’s quite easy to stay hydrated whether you’re driving, walking the dog, or taking your baby for a stroll with its convenient flip-top lid, which lets you use your bottle one-handed. And because the lid is attached to the bottle, there’s no risk of losing the cap in the process.

Another benefit of the pop-up lid is that it protects the mouthpiece from germs and dirt. Plus, you can–gently–throw your bottle in your bag or purse and it won’t leak.

By the way, we can’t forget to mention the enjoyable popping noise it makes every time you push the button.

The FDA food-grade silicone sleeve, which is available in 7 colors, not only offers protection from bumps and jostles of everyday use, but it also provides a nice firm grip. It also comes with a silicone strap for easy transport.

Also, all parts are obviously BPA-free and dishwasher-safe.

From camping, yoga and hiking trips to the urban daily commute, Nalgene’s classic 32-ounce water bottle was designed to perfectly fit any need and lifestyle. It’s also crazy affordable.

Made of heavy-duty, translucent Tritan copolyester, this American-made reusable water bottle is totally free of BPA, BPS, and phthalates as well as being virtually indestructible.

We’ve done all the research for you and found the best place to buy the Nalgene Tritan BPA:
Where to buy:
Specs & Features:
  • Material: Tritan copolyester
  • Capacity: 32 oz
  • Weight: 6.5 oz
  • Brand: Nalgene
What we like:
  • Strong construction
  • Durable
  • Leak-proof
  • Easy to fill
  • Easy to clean
What we don’t like:
  • Wide mouth opening makes it easy to spill while drinking
  • It doesn’t fit in car cup holders

It features a wide mouth opening which makes adding ice cubes and cleaning a breeze. However, this wide mouth hole is also a bit inconvenient, as it is quite easy to splash water and spill it all over your face.

The bottle is water-tight and suitable for both warm and cold drinks, but because this is a plastic water bottle, it will not keep your beverages insulated for long hours.

It also comes with useful volume markings so you can easily track how much water you’re drinking throughout the day. It’s quite easy to clean and dishwasher-safe on the top rack.

When it comes to construction, design, functionality, and price, it’s hard to beat the Takeya Originals Water Bottle. At least on balance.

It features a leak-proof, easy-to-drink-from spout lid, it’s BPA-free, and its double-wall insulation ensures your drinks–both cold and hot–will stay insulated for many hours.

We’ve done all the research for you and found the best place to buy the Takeya Black Originals:
Where to buy:
Specs & Features:
  • Material: Stainless Steel
  • Capacity: 24 oz
  • Weight: 12.8 oz
  • Brand: Takeya
What we like:
  • Comfortable carrying handle
  • Convenient spout
  • Lock-back cap
  • Great product for the price
  • Well insulated
What we don’t like:
  • Not dishwasher-safe
  • It doesn’t hold well for hot beverages

There’s also a small cap that locks all the way back so it doesn’t rest on your nose while you’re drinking as well as a wide loop handle for convenient transport.

The mouth opening is wide so it’s easy to clean and fill and its stainless-steel construction prevents condensation and it doesn’t absorb smells.

This water bottle by pioneering Brita does require a bit of recurring investment, as you’ll need to replace its filters once in a while (after 40 gallons or approximately every 2 months), but you can’t put a price on having purified and great tasting tap water.

It features a built-in filter, an easy-to-sip straw, and a leak-proof lid which comes with a built-in carrying loop for convenient transport. The filter improves both the taste and odor of the water by reducing chlorine and more with every sip.

We’ve done all the research for you and found the best place to buy the Brita Plastic:
Where to buy:
Specs & Features:
  • Material: Plastic
  • Capacity: 26 oz
  • Weight: 8.8 oz
  • Brand: Brita
What we like:
  • Water tastes super fresh
  • Leak-proof
  • The flip top keeps the straw from being exposed to germs and dirt
  • Dishwasher-safe
What we don’t like:
  • Couldn’t find anything!

The Brita Plastic Water Bottle is BPA-free, dishwasher-safe (top rack only), and easily fits in a car cup holder.

If you live in an area where drinking tap water is not safe, you should definitely give the Brita filtered water bottle a try!

Featuring a triple-insulated shatterproof stainless-steel construction, four different sizes, and a huge assortment of trendy colors to choose from, the Corkcicle Canteen is form and function at its best.

The brand took in mind nearly everything when designing this modern water bottle. It features their signature ergonomic flat sides for a comfortable grip as well as a silicone bottom, which prevents the bottle from sliding on slippery surfaces and eventually spilling.

It’s also BPA-free and it comes with a no-leak threaded screw top.

We’ve done all the research for you and found the best place to buy the Corkcicle Canteen:
Where to buy:
Specs & Features:
  • Material: Stainless Steel
  • Capacity: 25 oz
  • Weight: 14.4 oz
  • Brand: Corkcicle
What we like:
  • Strong insulation
  • Sleek design
  • Easy to hold
  • Leak-proof
What we don’t like:
  • Pricey
  • Lack of handle makes it inconvenient to carry
  • The twist-off top could be a bit taller so the fingers don’t rub on the mouthpiece

Its tough insulated construction will keep your drinks cold all day long. And by all day long, I truly mean 24 hours! It can also keep your hot beverages piping hot but for less than 12 hours.

When we said Corkcicle thought of almost everything with this bottle, we meant that they forgot to include a strap or a carrying handle for convenient transport.

Designed for traveling and outdoor adventures, the Platypus Platy Collapsible Water Bottle is a reusable, heavy-duty plastic bladder that can carry up to 2 liters of liquids. Once it’s folded, it will easily fit right inside a small pocket—perfect for your carry-on suitcase and hiking backpack.

It’s BPA-, BPS-, and phthalate-free as well as made from food-grade polyethylene lining, which doesn’t taste like plastic or retain flavors.

We’ve done all the research for you and found the best place to buy the Platypus Platy:
Where to buy:
Specs & Features:
  • Material: Soft plastic
  • Capacity: 70 oz (2.1 liters)
  • Weight: 1.3 oz
  • Brand: Platypus
What we like:
  • Lightweight and compact
  • Practical and versatile
  • Affordable
  • Solid construction—it seems durable
What we don’t like:
  • It takes forever to get rid of all the moisture inside the bag after cleaning
  • The caps are not attached so it can easily get lost
  • Not easy to carry once it’s full

The Platypus Platy Collapsible Water Bottle is very practical and versatile. It can serve you as a water bottle, an ice block, and a dirty water bag for filtering water for cooking when hiking or camping. However, the new threads are not compatible with Sawyer or other standard thread devices. It only accepts the Platypus GravityWorks water filtration system.

All in all, this is a great versatile, light, functional, and affordable outdoor gear.

“Hydration made simple.”–that’s what CamelBak promises us with their Chute Mag Water Bottle. And after testing it, we can indeed confirm that!

On the outside, CamelBak’s Chute Mag may look like your run-of-the-mill plastic water bottle, but after a closer inspection, we can testify this is a cleverly designed, functional, plastic water bottle.

We’ve done all the research for you and found the best place to buy the CamelBak Chute Mag:
Where to buy:
Specs & Features:
  • Material: Plastic
  • Capacity: 32 oz
  • Brand: CamelBak
What we like:
  • Sturdy construction
  • Clever design
  • Leak-proof
  • The comfortable handle and bottle’s diameter make it easy to carry around
  • Affordably priced
What we don’t like:
  • Nothing!

It’s lightweight while still feeling durable. Plastic materials are free of BPA, BPS, and BPF, it’s also dishwasher-safe for easy cleaning, and the cap is screwable, which means it won’t leak, but it will be tricky to operate with one hand.

It features a perfect mouth size, which delivers a great water flow, a built-in handle for easy transport, and the coolest feature we found, a universal cap designed with a magnetic handle that holds the cap out of the way while you’re drinking—an improvement from the previous model and the reason behind the “Mag” on the name.

Overall, an excellent everyday plastic water bottle.

Ideal for camping and hiking trips, but also for those who want to keep track of their daily water intake, the Roamer from S’well is a 64-ounce stainless-steel water bottle that makes staying hydrated an easy task.

The Roamer is also available in the 40-ounce model and despite its large size, the bottle comes with a handle, which makes it fairly easy to carry around. The price is equally hefty, but considering its construction and depending on your intended purpose, it’s worth every penny.

We’ve done all the research for you and found the best place to buy the S'well Roamer:
Where to buy:
Specs & Features:
  • Material: Stainless steel
  • Capacity: 64 oz
  • Weight: 1.9 lbs
  • Brand: S’well
What we like:
  • Amazing ice retention
  • Beautiful design
  • Solidly built
  • Can be used as a stylish thermos
What we don’t like:
  • Pricey—but worth it!

While this water bottle looks very much like a thermos, the design aesthetics have ingrained its utility in exercise routines and glamping in the way water bottles normally are used.

Its triple-layered, vacuum-insulated construction will keep your beverages cold for nearly 3 days and hot drinks for a little over a day. It’s also insulated with a copper wall layer that prevents condensation, and for your peace of mind, it’s BPA-free and composed of 18/8 premium food-grade stainless steel.

A nice alternative to a Hydro Flask bottle is the Thermoflask Insulated Water Bottle. Featuring a similar design, the Thermoflask bottle performs equally great, it has similar features, but at a more affordable price–at around $20.

It features a BPA-free double-wall stainless-steel vacuum insulation, which keeps drinks ice-cold for 24 hours and hot for up to 12 hours. Its stainless-steel construction doesn’t absorb flavors or odors, doesn’t sweat, and of course, it will not rust.

We’ve done all the research for you and found the best place to buy the Thermoflask Stainless:
Where to buy:
Specs & Features:
  • Material: Stainless Steel
  • Capacity: 24 oz
  • Brand: Thermoflask
What we like:
  • Clean design
  • Well insulated
  • Budget-friendly
  • 2 lids included
  • Leak-proof
What we don’t like:
  • It dents easily

Plus, a wide opening for convenient filling and adding ice as well as cleaning, a built-in handle for easy carrying, and the best feature of all, the Thermoflask comes standard with 2 types of leak-proof lids, a chug, and a straw one for added versatility and easy sipping.

It’s available in 24 oz and 40 oz sizes and in 5 different colors.

How to Choose a Reusable Water Bottle – Buyer’s Guide

Countless brands, different sizes and shapes as well as unique features make choosing the right water bottle an overwhelming task. But don’t fret!

We’re here to help you make an informed decision so you don’t drown in the crowded sea of water bottles and end up making a regrettable purchase.

In this buyer’s guide, we’ll cover the main things you should consider before buying a reusable water bottle:

Intended Purpose

Although water bottles are quite versatile, different lifestyles require different kinds of water bottles. For this reason, it’s important to first think about where you’ll be using your bottle most of the time.

Have you just completed a yoga session?

Do you need a water bottle to go camping and hiking or to bring with you to the office, school, and gym?

There are tons of bottles that are suitable for both the outdoors and urban daily life. But once you focus on the main purpose of your bottle, you’ll have a better idea on what size, shape as well as which material will suit you best.

Materials

Water bottles are primarily made of four materials: plastic, glass, aluminum, and stainless steel. Each one carries its own advantages and disadvantages.

To help you decide which material is most fitted to your needs, we’ve listed below the pros and cons of each one of them.

PLASTIC

Pros

  • The most affordable material
  • Lightweight, thus easy to carry
  • It’s dishwasher-safe
  • Safe for kids

Cons

  • Water doesn’t taste as clean and pure as it does in glass water bottles
  • It may contain BPA and other harmful chemicals
  • It can easily accumulate mold over time and start to smell
  • It doesn’t provide much insulation

GLASS

Pros

  • Free of industrial chemicals such as BPA
  • Water tastes the purest and fresh
  • Most are dishwasher-safe
  • Sustainable material

Cons

  • High price tag
  • It can easily break, therefore it’s not safe for kids
  • It might be heavy to carry
  • It doesn’t provide much insulation

ALUMINUM

Pros

  • A strong material, thus a durable option
  • Lightweight
  • Budget-friendly
  • Recyclable

Cons

  • It heats up in warm temperatures
  • It dents easily
  • It may leave a bitter, metallic aftertaste
  • It doesn’t provide much insulation

STAINLESS STEEL

Pros

  • It doesn’t leach chemicals
  • A strong material, therefore long-lasting
  • Excellent ice and heat retention
  • It is resistant to both rust and mold
  • Easy to clean
  • Most are dishwasher-safe

Cons

  • More expensive
  • Heavier than the aluminum and plastic ones
  • It heats up in warm temperatures
  • It may dent when dropped or banged

Ease of Use

The whole point of having a reusable water bottle is being able to carry it around with you throughout the day effortlessly. So keep an eye out for a comfortable handle or a strap for convenient carrying as well as if it fits in your car cup holder, backpack, gym bags, etc.

Ease of Care

Another essential feature to consider when hunting for reusable water bottles is to check how easy it will be to clean them.

Bacteria can build up fast in water bottles–no matter the material. That’s why it’s important to wash your water bottle regularly.

A few models like the Ello Syndicate Glass Water Bottle and the CamelBak Chute Mag Water Bottle are dishwasher-safe, but to ensure a thorough clean, we advise you to hand-wash both the cap and the mouthpiece.

In case your water bottle is not dishwasher-safe, you should invest in a good bottle brush or a toothbrush especially for the ones with a narrow opening.

Useful Features

Insulation

For optimal ice and heat retention, stainless-steel vacuum-sealed water bottles are your best choice. They will keep your beverages cold all day long and hot liquids for up to 12 hours.

They are the ultimate choice for camping and hiking.

Free of chemicals

Bisphenol A, also known as BPA, is an industrial chemical used in the production of some plastics and resins. It is often found in polycarbonate plastics and epoxy resins. The former is often used in food and beverage containers like water bottles while the latter is used to coat the inside of metal products, such as canned food.

This toxic chemical has been linked to causing reproductive, immunity, and neurological problems, as well as an increased likelihood of Alzheimer’s, childhood asthma, metabolic disease, type 2 diabetes, and cardiovascular disease.

Therefore, finding a BPA-free water bottle must be your #1 priority.

You should also be aware that Bisphenol F (BPF) and Bisphenol S (BPS), which have been used as alternatives to BPA have also started to raise concern over the increased risk of obesity.

Another toxic industrial chemical you should watch out for is phthalates, which is used to make plastics more flexible and harder to break. Phthalates might damage the liver, kidneys, lungs, and reproductive system. Again, no water bottles that we selected have any of the mentioned problematic substances.

    These are the steps you should follow:

    1. First, wash your bottle with soap and water
    2. Then, add a couple of tablespoons of white vinegar or a teaspoon of baking soda and fill the bottle with water
    3. Let it soak overnight
    4. Rinse out the bottle thoroughly the next morning (or run it through the dishwasher)
    5. Let the bottle air dry naturally

    🤓Why is bottled water bad?

    The plastic from bottled water often contains harmful chemicals such as phthalates and BPA. The former has been linked to an increased risk of cancer while the latter is known for causing hormonal disruptions in humans.

    It’s also important to note that water does not expire, but the plastic bottle does come with an expiration date. After that, chemicals start leaching into the water.

    Besides that, bottled water is equally bad for the environment because it contributes to the increase in ocean plastic waste.
