Platypus Soft Water Bottle Review:
Is This A Good Hydration
Choice For Hikers?

By Diane Spicer

Need an inexpensive one liter hiking bottle that saves space in your backpack? Check out the Platypus soft water bottle. #gearreview #hikingwaterbottle #platypusbottlereview #hikingforher

To begin this Platypus soft water bottle review, answer me this:

Have you ever had this problem?

  • You need to pack two water bottles for an airplane flight to your far off hiking destination, but have limited space in your luggage. Your rigid plastic water bottle takes up way too much room.
  • Or you want to go as lightweight and aerodynamically streamlined as possible on a backpacking trip: no rigid plastic or metal water bottles hanging off your pack.

Enter the solution: a collapsible soft water bottle.

This Platypus soft water bottle review was written just because I wanted to tell you about this solution to packing and storage problems that all hikers face.

I purchased the bottles with my own money.

No one asked me to write this review.

I just like sharing what works!

Platypus soft water bottle review:
the product

Platypus soft water bottle for hikingWhat's 6 inches by 11 inches (15 x 28 cm), flexible, weighs less than one ounce (24 grams), and can be slipped easily into your pack when it's full OR empty?

This little one liter (34 ounces) beauty!

The liner is food-grade, meaning it's designed to contact your drinking water without imparting anything nasty into your body.

  • The plastic is BPA free (read this for just a few of the reasons why you want to avoid BPA).

These hiking water bottles are made in the United States, by a reputable company with lots of experience with outdoor gear.

You have a choice of caps and designs, to keep things personalized and interesting. I went with a clear bottle so I could easily see how much water was inside, and a push-pull cap.

You can feel good about the clean, green aspect of these water bottles: because they are so lightweight, they use much less material which results in energy savings.

I purchased mine for Amazon's incredibly low price and they arrived in a few days, ready to be put to the test.

Prefer to shop elsewhere?

Platypus soft water bottle review:
field experiences

My initial concerns were twofold:

  • Would these flexible plastic bottles leak?
  • Would I swallow the taste of plastic when the hot sun heated up the bottles?

The first place I tested these bottles was in an airport, on my way to a New Mexico hiking destination.

Going through security meant the soft water bottle was rolled up and stowed empty in my carry on bag.

Then I filled it with water and carried it onto the airplane.

No leaking!

However, due to pressure changes, the water does tend to squirt out when you open the cap. Heads up if you don't want a wet shirt on the plane!

After 9 days of hiking in temperatures ranging from 75F to 90+F, carrying these one liter soft water bottles across sage brush mesas, down into the Rio Grande gorge, up steep wooded mountain slopes, and on casual strolls in towns, I am happy to report these observations:

  • No plastic taste. Period. Full stop. Quite amazing!
  • No leaking, even after rough trail usage.
  • Easy to hold in one hand.

More to love in this
Platypus soft water bottle review

  • Easy to clean bottle: spout is large enough to allow soapy water to fill all corners of the bottle and to permit thorough rinsing.
  • Sits upright when full.
  • Cap is easy to deal with. I have the pop up top with a small plastic cover to keep grit and bug wings out of my water.
  • Super easy on packing space: rolled up or lying flat, these hydration bottles weigh nothing and are almost invisible in your stack of clothing inside a suitcase or duffle bag.

Platypus soft water bottle review:
my conclusions

I'm a happy Platypus soft bottle owner, that's for sure!

I should have been using these years ago for my carry on luggage and on backpacking trips.

But to be completely honest...

A few drawbacks to note in this
Platypus soft water bottle review

1. The small plastic cap which covers my top is easy to misplace, and could get blown away in a stiff breeze. Stow it in your pocket until you need to cover up your cap again.

2. These soft water bottles are not easy to dry, once you're at home and have washed them thoroughly.

  • In fact, it's been 6 days since I began the drying process, and there is still a lot of condensation inside of them.
  • I've decided that storing them filled with water is the way to go. This will play into my "emergency preparedness" plans, living in earthquake prone territory as I do.
  • But it could also be useful for regions which experience frequent power outages, winter storms, or intermittent water shortages.
  • Storing a full Platypus soft water bottle in your car is a smart idea, too.

3. The push-pull cap was a bit dicey when my hands were gritty with trail dirt. There are other closure options, for those who prefer a hydration hose system to avoid this problem.
