Three Insulated BPA Free Water Bottles

Insulation has become essential for me when choosing new water bottles, but so has the need for something that doesn’t expose my body to any unnecessary chemicals. If you’re in the market for a new device to store hot or cold beverages this summer, let’s take a closer look at three insulated BPA free water bottles.

Hydro Flask Insulated Water Bottle

This 64-ounce behemoth comes with a wide mouth for easy sipping and cleaning. Each of these Hydro Flasks is manufactured with non-toxic, BPA-free plastics and 18/8 food-grade stainless steel. They’re also powder-coated, which helps to ensure a slip-free grip.

This can actually come quite in handy when you’re talking about a water bottle with 2 liters of capacity. Hydro Flask’s powder coating also works seamlessly with their TempShield insulation to ensure condensation doesn’t form on the exterior of the bottle.

This is the perfect insulated BPA free water bottle to hold all of your hot or cold liquids for a long hike or extended day out climbing at your favorite wall. It’s also a convenient bottle to bring along on backpacking trips because the wide mouth will fit most backcountry water filtration systems.

Hydro Flask’s double-walled, vacuum insulation system has been tested and proven to keep hot drinks hot up to 6 hours and cold drinks cold up to 24 hours. Additionally, this Hydro Flask features a cap with Honeycomb insulation, which actually helps to ensure minimal heat loss, regardless of whether you’re storing hot or cold liquids.

Bear Grylls Insulated Water Bottle

The 32-ounce Bear Grylls water bottle is another great (and healthy) option! With a weight of just 12.7 ounces when empty, this bottle ranks as one of the lightest of its size. It’s actually 20% lighter than the leading competitors!

It also features an innovative, triple-walled design that will keep beverages hot for up to 12 hours and cold for up to 24 hours. It also features a no-slip exterior grip to help you keep it firmly in hand when you need it most.

The bottle is manufactured with scratch-resistant, food-grade steel, which means it won’t hold odors or flavors. Its powder-coated exterior will also stand up against drops, impacts, and scratches.

The bottle’s vacuum insulation and the leak-proof lid will ensure that the valuable liquids you store in it stay where you want them, instead of ending up on the floorboards of your car or the bottom of your backpack.

Tree Tribe Stainless Steel Water Bottle

From the brilliant minds at Tree Tribe, I bring you this indestructible, insulated, eco-friendly, 100% leak-proof, BPA free, plastic-free, double-walled, wide-mouth water bottle for your hot and cold liquids. The makers of this water bottle designed it with a durable, 18/10 stainless steel outer shell and food-grade 18/8 stainless steel interior.

The bottle offers a double-wall, vacuum-sealed design keeps hot beverages hot up to 12 hours and cold beverages cold for much longer. The airtight silicone lid gasket in this bottle was included to ensure that it never leaks, which allows you to keep a variety of beverages without concern (think soups, smoothies, coffee, etc.).

Tree Tribe cares about reducing plastic waste, which is why they used zero plastic in the manufacturing of this water bottle (note the bamboo cap!). It is also why they have committed to planting 10 trees for every water bottle that they sell. They believe that keeping water cold and coffee hot is what a water bottle should do, but they also believe in giving back to this wonderful earth that we are going to be enjoying once we have their amazing water bottle at our side.

So What’s the Difference Between These Water Bottles?


Well, size for one. The Hydro Flask is your ‘Grande’ size, coming in at 64 ounces. Coming in at half that size is the Bear Grylls bottle at 32 ounces. Tree Tribe lets you choose from three sizes (12, 20, and 34 ounces) depending on your preferences.


All of these bottles employ stainless steel and vacuum insulation as their primary method of keeping hot things hot and cold things cold. Unlike the Bear Grylls and Hydro Flask bottles that use a BPA-free plastic liner to ensure that your liquids don’t take on a metallic taste, the Tree Tribe bottle doesn’t use any plastic whatsoever.

Brand Trust

There is also the question of which brand you trust, which might be difficult in this case. Bear Grylls has built a stellar reputation for sharing essential survival knowledge and attempting numerous daring feats on television. Hydro Flask is a very well-recognized brand that produces high-quality products (I speak from experience).

Environmental Responsibility

And then there’s Tree Tribe, which (if you’re like me) you may have never heard of until now. But when you consider their commitment to environmental sustainability and conservation, it certainly makes paying a little extra for their products worthwhile.

BPA Free Water Bottle Buyer’s Guide

Choosing the one that’s right for you depends on a number of factors. If you’re trying to maximize your carrying capacity, then the 64-ounce Hydro Flask is probably the best choice.

If you just ate two full bags of popcorn and can’t seem to hold anything in sight to wash it down with water, then the no-slip grip of the Bear Grylls bottle could come in handy.

And if you care about the environment and want to purchase products from companies that commit to give back, then you’ll likely be drawn to Tree Tribe.

Most importantly, all three of these bottles are insulated BPA free water bottles. They’ll keep your desired beverages at the temperature you desire and they’ll last a long time (no guarantees because it always depends on how you use it). And lastly, they won’t result in weird levels of bisphenol-A (BPA) winding up in your body without you realizing it!

    Thanks for the great post.  I’m in need of a new bottle and am still having difficulty selecting one.  I’m not much of a hiker or what not and am looking for one that will fit in my drink holder in the car.  That said, I believe the Hydro Flask is out.

    What are your thoughts on the triple walled vs double walled options of the Bear Grylls and the Tree Tribe options?  Off the top of my head I think 3 is better than 1 but then there are other factors such as how much space is in between them and so on.

    Their price points are not much different.  Based on my needs/use what do you think is the better choice for me?

    Thank you,

      Thanks for the comment Scott! 

      For my money, the Tree Tribe bottles would be my choice every time. I actually have a set of 10 that I use in the summers when I lead kayaking trips. They keep water ice cold all day, fit in the cup holder in the center of our kayaks, and it’s helpful that the company makes a donation for every bottle purchased!

    The 64 ounce water bottle size looks just right for me. These are great water bottles, and I know they are definitely a healthier option than my old and worn plastic one, even though the label said BPA free when I bought it. I am sure over time and with age, the plastic does start to deteriorate after a while and you probably end up drinking more particles than you should.

    I would just like to find out if these bottles break if you drop them. I know with condensation and all they all do become slippery, no mater what the manufacturer tells you, and every now and then accidents happen, so just how break proof are they?

      Great question! While the exterior of these bottles will withstand most drops, they don’t claim to be “bomb-proof” like Nalgenes (although I’ve found this not to be the case). The danger with these metal water bottles is actually that the insulating layer, which is located between interior and exterior walls, breaks. The good news is that this won’t render the bottle unusable. It just means that it won’t be as effective at keeping hot liquids hot and cold liquids cold as it was when you first bought it.

    Hello, I see you have done so much work for us here, thank you. I have always wanted to map out my options but it takes so much time with all the water bottles available ya know. I like these healthy, durable options listed here. Living in the country, I find myself exploring nature. Its easy to become dehydrated and realize that you are far from any clean water source. I especially like the idea of having extra water so thanks for providing the 64oz. option.

    This post has made me think about investing, thank you.
