Many brands have naturally gained a lot of recognition and customer loyalty due to their ability to serve the intended purpose. Today we’ll enter into the Hydro Flask vs YETI water bottle debate.

hydro flask vs yetiWhat’s a vacuum insulated bottle?

Before reviewing the products, it’s essential to understand the difference between a vacuum insulated water bottle and normal single-walled water bottle.

Simply, a vacuum insulated bottle is similar to one bottle nested inside another bottle. There’s a sealed vacuum in between the two bottles.

Why use a vacuum insulated water bottle?

Today, most people are looking for ideal reasons why vacuum insulated water bottles are superior to other bottle types.

To correctly explain the above, you’re required to understand some heat transfer physics in vacuum insulated water bottles.

When it comes to a single-walled water bottle, the heat transfer in both the inside and outside is relatively quick by means of radiation, conduction, and convention.

Therefore, when you fill such a bottle with hot water, the outer walls of the bottle will become hot through conduction.

On the other hand, the rules change completely when it comes to vacuum insulated water bottles, whereby heat isn’t transferred by convection or conduction, but rather by radiation.

This, therefore, means that the vacuum insulated water bottles can maintain a specific temperature over a given time compared to the standard water bottles. They keep hot drinks hot and cold drinks cold for an extended period.

Hydro Flask Vs. Yeti Overview

Now that you know the difference between vacuum insulated water bottles and standard water bottles, we go further deeper to determine the best vacuum insulated water bottle in the market. In our case, we’ll review the Hydro Flask and Yeti water bottles.

Regardless of your choice, you’ll get a fantastic insulated bottle that can serve you for a long time. Although it’s a requirement that every competition must have a winner, below are some top factors to use in the debate over which is the best.

However, before we go to these factors, let’s have some company history of the two competing brands.

Hydro Flask Joshua Tree National Parks edition water bottle.

Hydro Flask

This is the most popular brand.

The company came into existence in 2009 and has managed to take a large market share for the insulated water bottles.

It has managed to come up with a diverse catalog of colorful and functional bottles that are used widely.

Hydro Flask has used insulation technology to come up with ideal food storage containers.

The company is also utilizing technology to come up with improved features, new styles, new accessories, and more customizable water bottles.

Shown here is the Joshua Tree design from the popular National Parks series.

These aren’t available everywhere but I got mine right here and the shipping was super fast.

I am getting emails about how these are hard to find but I also saw them available here.

In addition to the Joshua tree design, they also have Grand Canyon, Great Smoky Mountains, and Olympic Hydro Flask bottles.


YETI bottles have a devoted following and a lot of people I know who work crazy long hours are devoted to these bottles.

They collect them and they tell me they get excited when someone in the office shows up with a new one. I know it seems odd maybe but this was how I first realized how popular this brand is.

The Yeti insulated water bottles are reputable for making drinks colder. I have the temperature test results showing that’s really no exaggeration.

The company started its operations in 2006 and has managed to retain its reputation as a leading brand in vacuum insulated water bottles.

Today, the company is a world-class contender when it comes to stainless steel water bottles.

Hydro Flask Vs. Yeti Comparison

Both insulated water bottles come in a variety of sizes and colors. Below is a comprehensive explanation of settling the score between Hydro Flask and Yeti insulated water bottles:


All experiments that have been undertaken for to determine the best insulated bottle between the Hydro Flask and Yeti, practically give identical results.

In one experiment that was done, a 40 Ounce Hydro Flask bottle and a 36 ounce Yeti bottle were both filled with 40-degrees water with some ice chunks floating on it and sealed properly, and left for 24 hours.

Immediately after the 24 hours elapsed, the ice chunks had melted and the water temperature in both bottles had risen by 6 degrees. They both read 46 degrees.

After the experiment was repeated, similar results were obtained. It’s only in the third experiment where the Yeti had a variation of 2 degrees concluding that the two water bottles have almost equal insulation.


Both insulated water bottles have relatively high prices that relate to their quality. However, Yepi insulated bottles have slightly high prices than the Hydro Flask bottles.

For instance, a 32 Ounce Yeti bottle goes for around $50, whereas a 40 Ounce Hydro Flask is $8-10$ cheaper.

Although most people see these price tags as unrealistic for a water bottle, they’re worth the investment since they can last longer provided that one takes proper care. In terms of price, the award goes directly to Hydro Flask since the Yeti brand charges extra money for such a comparable product.


In terms of durability, the results are the same since both are made of 18/8 food grade insulated stainless steel which is usually hardcore. The only risk comes when we talk about puncture or dents on their outer walls.

However, over the past few years, customers have showered both bottles with many reviews, although statistics show that the Yeti seems to be slightly durable than its counterpart Hydro Flask.

The race again becomes tight in terms of accessories, although, to some extent, the Hydro Flask seems to be much ahead with a very narrow margin. Both bottles have plenty of accessories ranging from caps, sleeves, holders, among others, which change both their look and function. The Hydro Flask has a pool of ever-growing accessories compared to the Yeti.


Both the two insulated water bottles have a modern look, which can make leave you confused, especially if you’re unfamiliar with them.

Both are great looking bottles. However, if you go beyond a basic model, the Hydro Flask tends to offer a variety of options in terms of color schemes, color palette, limited edition bottles, among other features.

Hydro Flask vs YETI Hot & Cold Temperature Test Results

Hopefully this chart will help you determine a winner in the Hydro Flask vs YETI debate. We started the tests with comparable conditions for each bottle and they were placed in a 72-degree (F) room for the entirety of the test.

Both bottles remained perfectly dry the whole time, no moisture accumulated on the outside surface or as a “ring” below the bottle, no sweating whatsoever. As you can see, they’re pretty similar in terms of maintaining cold temps.

Maybe the determining factor will be whether you want better long-term performance for hot beverages? If so, your winner is the YETI.
