You’re also getting a protective spout cover that’s meant to shield you from any germs and dirt that may latch onto the exterior of your bottle from just about anywhere.

The lid is also top-rack dishwasher safe, although you’ll have to clean the body manually i.e. with your hands.

This bottle is manufactured in accordance with USFDA’s requirements and it’s made of Eastman Tritan co-polyester, BPA-free plastic.

And while there are boatloads of different colors to choose from, it’s good to know that Nalgene uses only FDA-compliant colors.

Gatorade needs no introduction and neither does its highly-successful squeeze water bottle that’s designed to be as sports-friendly as possible.

First and foremost, this is one of the cheapest reusable water bottles that you’ll ever stumble upon, although it comes from a reputable brand, which is good news.

Now, this bottle comes with a hands-free pressure-release dispenser tip and a high-flow valve that’s meant to eliminate any liquid spillage.

Check Price on Amazon

Other than that, this bottle is made of BPA-free plastic and sports (see what I did there?) an easy-grip design for effortless use.

Also, squeezing this bottle is very pliable, although you can always opt to remove the lid and drink straight from the adequately wide 2-inch opening.

This robust, yet comfortable bottle can be attached to your backpack, rolled up to take up less space and you can even loop it around your wrist for added convenience.

It’s incredibly portable, versatile and we really like the fact that the body is made of shatter-proof silicone that adds extra sturdiness.

Additionally, all the materials used are food-grade and free of any harmful chemicals as well as BPA, PVC and BPS so there should be no plastic odor or taste.

This Nomader collapsible bottle also utilizes a patented twist cap design that includes a hygienic spout cover as well that’s meant to prevent you from consuming any nasty germs and dirt.

Weight (empty): 7.6 oz
Mouth (opening):
3.00 inches
Price: $

This water bottle is ideal if you’d like to get rid of that nasty chlorine taste and odor associated with tap water.

The way it removes chlorine and other chemical contaminants is quite simple – the in-built filter filters the water while you’re drinking.

And according to the manufacturer – Brita, 1 filter has the ability to replace 300 regular single-use plastic bottles and the filter can last up to 40 gallons (or 2 months).

Check Price on Amazon

Also, this Brita bottle also relies on a BPA-free, hard-plastic design with the addition of an enclosed straw for extra convenience.

On top of that, you can put the big closure and the push/pull cap in a dishwasher.

However, you’re supposed to remove the filter before doing so although I don’t think there’s a dire need to use the dishwasher to clean this bottle – just rinsing it should suffice.

Pros:

  • Comes with a built-in filter
  • Dishwasher-friendly
  • Very affordable
  • Lightweight

Cons:

  • The filter has to be replaced
  • Lacks double-walled insulation

Mouth (opening):
1.00 inches

Although this compact water bottle is ergonomic and dead easy to drink from, its biggest perk is probably the fact that it’s dirt cheap!

This means that the plastic materials used are both dishwasher-safe and impact-resistant so hooray for that.

Check Price on Amazon

Best water bottle, how to choose the right bottle for you

How to Pick The Right Water Bottle For You? [Buying Guide]

Before you buy your awesome brand new reusable water bottle, there are a few key aspects that you have to consider!

Plastic, Glass or Stainless Steel?

The 3 main types of reusable bottles are plastic, glass and stainless steel.

And here are the pros and cons of each:

1. Plastic Water Bottles

Pros:

  • Lightweight
  • Durable
  • Easy to clean

Cons:

  • Not insulated
  • Can give off funny odors and flavors

2. Glass Water Bottles

Pros:

  • Doesn’t impact flavor and taste

Cons:

  • Fragile
  • Heavier

3. Stainless Steel Water Bottles

Pros:

  • Very robust
  • Typically vacuum insulated
  • Maintains heat longer

Cons:

  • Subject to denting
  • Might give off a metallic taste

Size and Dimensions

Although a 32-oz capacity might catch your attention, you have to realize that the bigger the capacity, the larger and heavier the bottle will be.

That’s why most brands out there generally have several different sizes on offer, mostly ranging from 12-32 oz., although higher-capacity bottles do exist.

Regardless, you should carefully consider what values more to you.

Do you need a lighter and smaller bottle or a massive water bottle that can keep you hydrated longer?

Putting things into perspective, this is what to expect from different capacity bottles:

  • Smaller capacity – Lighter, thinner, more compact
  • Larger capacity – Can hold heaps of water/liquid, usually with a wide mouth diameter

Thus, if you’re going to be somewhere camping for a few days, then, by all means, go for a larger capacity bottle.

But if you’re going to be backpacking or hiking, then a more compact bottle would be the better option as you won’t have to carry that much weight in your backpack.

What Lid Type to go For?

Each reusable portable water bottle comes with a particular lid design that you may or may not like.

The most common lid design types are:

  • Flip-top spout lid
  • Screw top lid
  • Straw lid

Honestly, it’s down to personal preference which lid type is better over the other.

With that being said, flip-top and straw lids tend to be easier to use as you don’t have to screw and unscrew the top lid each time.

Although some folks prefer the old-school appeal of a screw top lid bottle and the sense of security it offers.

But if you’re an avid backpacker or hiker, then perhaps you’d want a water bottle with a carabiner lid  that you can attach to your backpack.

FAQ

Are reusable water bottles safe?

Yes, it’s safe to use a reusable water bottle, especially if you’re properly cleaning it on a regular basis.

That’s because the nature of these bottles and how they’re used typically includes the appearance of moisture.

Perhaps you’re pouring really hot or cold liquids into the bottle and/or there’s a significant difference between the outside and inside temperature (inside the bottle).

So when you neglect cleaning your bottle and when it’s exposed to moisture, the growth of harmful bacteria might eventually take place.

And while reusable bottles made of glass are probably your safest bet when it comes to how safe they are (see what I did there?), stainless steel and plastic are perfectly fine too.

When the glass is cooled or heated it won’t leach harmful chemicals into the water or liquids inside your water bottle.

Because glass is made of natural materials, there is no danger of inorganic chemicals leaching into liquids when it’s heated or cooled

What really matters here is to clean your water bottle on a regular basis.

Still, if you use a plastic bottle, make sure that it’s listed as BPA-free.

Can you save money by using a reusable water bottle?

Yes, you most definitely will be saving cash if you start using a reusable bottle for your hydration needs.

Just think about how often you buy one of those nasty disposable plastic water bottles when you’re thirsty.

Well, now consider how much you can save if you stop buying single-use bottles and instead bring your reusable water bottle with you, wherever you go.

For instance, if you have a reusable water bottle that costs $12, you could be saving around $160 on a yearly basis!

And while this might be just an estimation and an example, a reusable bottle will most definitely help you to spare your bank account.

Even better, by not using disposable bottles you’re doing your fair share in helping preserve the environment!

How do reusable water bottles help the environment?

Reusable water bottles help the environment in several primary ways since they:

  • Protect the oceans and marine life
  • Need less oil to be produced, compared to dispensible water bottles
  • Produce less harmful emissions in the atmosphere

There’s no doubt that single-use plastic bottles keep piling up in various landfills across the globe and that’s a serious environmental issue.

Reusable bottles, on the other hand, are much less likely to end up in a landfill, although sooner or later you’ll still replace it but definitely not as frequently as standard disposable bottles.

Or in other words, reusable water bottles are much better for the environment than single-use bottles in every possible way.

Which plastic bottle is safe for drinking water?

The ones listed as BPA-free and plastic bottles labeled 1 or 2 as these are considered safe.

On the other hand, bottles labeled with the numbers 6 and 7 are supposed to be avoided.

However, while BPA is a known hormone disruptor, it’s far from being the only chemical with estrogenic activity.

In fact, a study published in the Environmental Health Perspectives journal found that almost every plastic product that they tested leached some sort of EA (estrogen activity) chemicals (1).

Conclusion

So based on our extensive research, our top pick is undoubtedly the Hydro Flask Water Bottle .

It combines a unique blend of durability, superb material quality, great leak-proof design and brilliant reputation while also being super easy to clean.

But that doesn’t mean that you shouldn’t check the other bottles that we’ve hand-picked for our top 10 list.

Especially since you’ll find various categories of reusable water bottles, from models with a built-in filter to collapsible ones and even bottles for kids!
