6 Eco Friendly Water Bottles For More Sustainable Sipping

Staying hydrated is essential; using single-use plastics is not.

Producing a plastic water bottle requires six times as much water during manufacturing as what ends up in the bottle itself.

Whereas using an eco friendly water bottle is one of the most impactful swaps you can make…and the effort of doing so is minimal.

Any brand that steers us towards plastic free water bottles is inherently better but there are some that go above and beyond to keep us and our planet happy, hydrated, and healthy.

Wave Case, for one, keeps it nice and simple with one of the best eco friendly water bottles for keeping drinks hot or cold.

The rainbow of colors is one reason many folks love Hydro Flask, but we love them for their lifetime warranty and gallon-sized giving initiatives.

They also make epic zero waste gifts for your mindful loved ones.

If you need further justification for making the switch to a sustainable water bottle, as well as how we filtered for these brands, skip to the bottom of the article.

About S’well

Sarah Kauss set out to create the first “reusable hydration accessory,” long before sustainable was stylish” or vice-versa.

Using clever industrial design that looked nice and kept liquids insulated, Swell’s environmentally friendly water bottles were born.

They keep things cold and hot for 48 hours and 24 hours, respectively. Kids can sip sustainably, too, thanks to their kid-friendly S’ip Bottles. 

They also have Travelers, Roamers, and a range of other bottles to quench any type of thirst (even if it’s just thirst from the dehydrating magic we call coffee).

S’well’s Ethical and Sustainability Practices


Triple-layered, vacuum-insulated, high-grade 18/8 food-grade stainless steel is the material of choice for S’well and their sustainable water bottles.

Therma-S’well insulation technology keeps drinks hotter or colder, for longer, and keeps the outside of the bottle from sweating. 

Supply chain & labor practices:

These ethical water bottles are thoughtfully designed in NYC and manufactured in a responsible manner in China. 

As S’well is a Certified B Corp, annual audits for strict environmental and social standards stand as evidence for that.

Green business practices:

S’well uses minimal packaging that includes compostable cardboard and responsibly harvested paper. 

Community & charitable giving:

A proud partner of UNICEF, this brand that gives back has provided more than $1.4 million in safe and clean drinking water to vulnerable communities around the globe in three years.

S’well is currently focused on Madagascar, where nearly 50% of people lack access to clean drinking water.

These reusable water bottles are made from pro-grade 18/8 stainless steel powder coated for durability and an easy no-slip grip.

They are insulated using TempShield™ power, which keeps drinks cold for 24 hours and hot for 12 hours.

All of the eco bottles are free of BPA and phthalates and also come with a lifetime warranty. 

Supply chain & labor practices:

Hydro Flask is the name in sustainable stainless steel water bottles, but they currently don’t appear to address manufacturing and material sourcing on their website, so we will reach out directly to ask. 

Green business practices: 

The most sustainable water bottles are those that last, which is why theirs are backed with a lifetime warranty.

Not that it’s needed for these practically indestructible bottles.

We personally own one of their coffee sized bottles and it looks virtually new after years of being thrown around.

Hydro Flask launched a charitable program called Parks For All that is designed to create and support green spaces.

About Origin

What happens when you combine eco friendly glass bottles with the knowledge that your sipping will fund sustainable poverty alleviation programs around the world and provide clean drinking water to those without?

Origin, that’s what.

Aware that access to clean water can reduce preventable disease and mortality rates, they donate 2% of their revenue to solutions that support those living in extreme poverty.

Their eco friendly glass bottles include a wide and narrow option, a fruit/tea infuser bottle, and a few kid bottles.

Origin’s Ethical and Sustainability Practices


THese ethical water bottles are made with medical-grade borosilicate glass (think: Pyrex) that don’t expand or contract too in extreme temperatures (i.e. no cracking).

They’re free of BPA, BPS, lead, cadmium, and PVC.

Unlike metal, you won’t have the issue of bacteria growth or rust.

Even the leak-proof bamboo lid is equipped with a food-grade silicone ring to prevent chemicals leaching into your water. 

They also come wrapped in a food-grade silicone sleeve that provides impact protection when the extra grip isn’t enough to stave off the occasional drop. 

Supply chain & labor practices:

No supply chain information is available for this brand and their FAQ section is currently blank.

Community & charitable giving: 

Not only do they provide the resources to support access to clean water, but Origin also provides education to improve literacy rates, and empower women and children with access to health and hygiene solutions. 

They do this through partnerships with both community members themselves and organizations rooted in sustainable development.

One such partnership is with Empower Playgrounds, which builds merry-go-rounds that generate electricity during play at primary schools in rural Ghana villages.

The electricity charges battery-powered lanterns which the students take home and use to study and read.

We’re pretty sure the answer to that is a big “DUH”, but just so we’re all on the same page on how prolific the plastic problem is, here are (a few) facts.

A single-use PET plastic bottle takes 700 years to start breaking down—and when it does, it releases microplastics into our environment. 

There’s also the fact that 1.5 million barrels of oil are required to produce the plastic needed for our single-use bottles (and this is for American consumers only).

Considering the fact that 90% of the cost of a plastic water bottle is for the plastic itself, it doesn’t even make sense from a financial standpoint—and certainly makes spending a one-time $20-$40 on a reusable bottle much more reasonable.

In the US alone, each of us goes through about 315 plastic bottles every.single.year.

Even if you cut that consumption in half by occasionally remembering to bring your eco friendly reusable water bottle with you, that could still have a hugely positive impact. 


How did we decide what eco friendly water bottle brands were truly putting their money where their mouth is (so we can do the same)? 

 By considering the following key criteria. 


The best water bottle materials to drink from are most importantly non-toxic. BPA free was a non-negotiable here. 

For this list, that meant either glass or eco friendly metal water bottles made from food-grade stainless steel. 

Stainless steel is one of the most eco friendly water bottle materials because it’s not only safe, but very durable and infinitely recyclable.

Food grade silicone bottles would be an option here, as well, though we didn’t find any suitable silicone brands just yet, outside those using silicone sleeves for extra grip.

But is silicone plastic and eco friendly? In short it’s not a straight forward answer and very much depends on the grade and way in which it is manufactured.

While there weren’t any on this list, eco friendly aluminum water bottles are also good, provided they specify BPA-free (plastics aren’t the only material that carries them).

While there are some brands out there using recycled plastic to make BPA-free reusable water bottles, we prefer to avoid plastic altogether.

Supply chain and labor practices:

Unlike with sustainable jewelry or ethical fashion, a traceable and transparent supply chain doesn’t seem to be front of mind for eco-friendly water bottle brands, yet.

Most brands haven’t satisfied our thirst when it comes to letting us know about their supply chain and labor practices, but we were happy to see that some brands are working with a strict code of conduct or are certified by the ILO to have ethical and sustainable supply chain practices. 

For all brands on the list, we’ll be reaching out to learn more about their manufacturing.

Green business practices:

We were happy to see the larger ones offsetting their carbon emissions, using recyclable packaging, planting trees, or using renewable energy.

The best sustainable water bottle brands were those offering lifetime warranties and adding extra touches (like a protective powder coat) to increase durability. 

Community & charitable giving:

This is where staying hydrated can make a positive impact outside personal health and wellness. 

Whether it’s planting trees around the globe, giving their staff members paid volunteer days, or providing people in need with access to clean drinking water (because not every country has the cleanest water in the world), we love quenching our literal thirst and thirst for social change at the same time.  


What are you waiting for?

Grab your sustainable backpack, tools to purify water and your eco friendly water bottle and enjoy the adventure! 

You know how bad single-use water bottles are for our planet, so let’s support the brands who are offering us a sustainable solution. 

That said, the most eco friendly water bottle is the one you already own, so only buy new if you need to, and remember to ask (in every situation), “Do I have my water bottle?”

Don’t let it end up the water bottle graveyard of your gym’s lost-and-found.

Go remind your friends to stay hydrated by passing along this article, so they too can help keep our planet an H2O-asis!
