Hiking water bottles: when did it all get so complicated?

I logged onto an outdoor gear website recently, and just for fun, typed in the innocent words "water bottle".

  • Up popped 12 pages, each containing 20 items.

I have to admit, I'm puzzled.

The basic issue here is simply hydration for the trillions of cells in your hard working hiking body.

So why so much fuss over how to get water from a containment unit called a bottle, to your lips??

Let's take a look at some of the hidden issues in choosing the best hiking water bottle for your hiking style.


Beware of BPA

Plastic water bottles have been around for a long time.

In fact, as demonstrated by my small Internet search above, there are plastic water bottles galore.

However, you want them to be free of a chemical called bisphenol (BPA).

Why is BPA free important? That link explains.

Long story short: Current research suggests it can cause a lot of trouble.

So go BPA-free with your water bottles. It's not hard to do with reputable brands.

  • Beware plastic bargain brands that are super cheap and don't state "BPA free" on the label.


Your options
in hiking water bottles

Plastic water bottles used on a hiking trail were the only choice when I began hiking several decades ago. (true story)

  • Most of us ancient backpackers used empty soda bottles over and over again until they either fell apart or starting tasting funny (NOT recommended hiking best practices!!).

When shopping for lightweight plastic water bottles these days, you have options beyond bottles.

  • You could carry your hiking water in bladders.

Hiking water bottles are also made of stainless steel or aluminum, either single wall or double walled for insulation.


Strong points of metal bottles for hiking

  • Inert, so won't react with your electrolytes or lemonade to produce a weird, possibly hazardous, taste.
  • Nearly indestructible, so dropping them down a rocky chute won't be the end of them. 
  • Come in a dazzling array of color choices, and have interchangeable lids for water delivery: flip up straws, twist off lids, twist or pop open lids and more.
  • You can't accidentally slice them open on a sharp rock.
  • They don't disintegrate from UV ray exposure (sunlight) or extreme temperatures after several uses, as with plastic bottles.


Drawbacks of metal hiking water bottles

  • A bit heavier in your backpack compared with plastic. When weight is your top consideration, go with plastic.
  • They can be dented when dropped. 
  • On cold winter days it's a bit unpleasant to bring an ice cold metal water bottle up to the lips.
  • The duct tape I wind around each bottle (part of my "be prepared" ten essentials strategy) sometimes gets tightly stuck to the metal, especially if it has gone through temperature extremes.

All of which begs the question:

Which are the best hiking water bottles?

Best for what?

And for whom?

It depends upon the hiker, no surprise there.

But I'll put in my 2 cents worth here, and welcome any debate on the matter.

I carry stainless steel bottles, and I don't begrudge the slightly heavier but sturdier (compared with plastic) design.

Why did I switch from my Nalgene plastic bottles?

They were over 2 decades old, scratched and battered.

And when I read about the BPA scare, that motivated me to make the switch.

  • Nalgene has reformulated their water bottles to eliminate BPA, but if you're still carrying around old ones, toss them in the recycle bin. Go ahead, I'll wait here for you to get back.

So after a little research, I bought some metal bottles, and have not regretted my decision.

Here's the newest kid on the block: Hydro Flasks.

These bottles have some advantages over the Kleen Kanteens, while sharing many of their strengths for hiking hydration.

Specifically, they are double walled, so there's no condensation when temperature extremes occur in one day.

And they come in some mighty attractive colors!

Check them out here.

And note that you can use the larger ones for car camping.

When to use
plastic hiking bottles

Frankly, plastic spooks me.

We are exposed to so much of it, in our living environment, our food supply, our health care. Time for a break!

Stainless steel is inert, it's durable, and it's standing up to all of the punishment I throw at it on the trail.

ot I'm not going back to copolyester, polyethylene, polypropylene -  unless there's a good reason to do so.

Clean water only, please!

Not to be too basic, but be sure the water you're drinking is safe before you fill up your hiking water bottles!

UPDATE: I'm an old fashioned girl, but I've made room for powdered electrolytes in my hiking water recently.

They are non-reactive with both my plastic and metal bottles, and not only replace the ions I'm losing in sweat (sodium, etc.) but they taste great, too.


What kind of hiking water bottles
do you use?

I'd love to hear what you carry on your hikes, and why.

And what's in your water transport devices?

Maybe water bottles are not your cup of tea (or choice for water transport).

Instead, you could check out hiking hydration backpacks.
