KK and HF are by far the best brands of water bottles. All products from both brands have different durability, resistance and materials. In addition, each brand uses its own method to preserve the temperature of stored liquids.

Many people have mixed opinions on these two brands. Some prefer Klean Kanteen while others prefer Hydro Flask. Certainly, each brand has its pros and cons. However, depending on the user’s requirements, a particular brand seems to be much better than the other.

If you’re thinking of buying the best bike water bottle from one of these two brands, but you aren’t sure which one to choose, don’t worry. In this review we’ll make a comparison between Klean Kanteen vs Hydro Flask to help you make the best decision.

Klean Kanteen Vs Hydro Flask

1. Insulation method

HF and KK use a thermal insulator between two stainless steel walls to keep the temperature of stored liquids stable. The insulated center prevents thermal interaction between the internal and the external environments. For that reason, your hands won’t feel any temperature change when you grab the bottle.

Tempshield Insulation is the name of the thermal preservation method used by Hydro Flask. It can stabilize the temperature of hot liquids for half a day and cold liquids for a full day.

On the hand, Klean Kanteen uses a thermal preservation method known as Climate Lock Insulation. It can stabilize the temperature of hot liquids for 20 hours and cold liquids for 50 hours. However, in reality, Klean Kanteen has the same performance than Hydro Flask preserving hot liquids.

So, the main difference between both brands is in their capacity to keep drinks cold. And without a doubt, Klean Kanteen is the winner this time.

2. Design

At first glance, KK and HF water bottles are very similar between each other. Both products are made of powder coated 2.25-mm stainless steel. This results in superior resistance to high impacts and scratches, less interaction with the external environment and no water condensation on the bottle surface.

However, both water bottles have a slight difference on the design on the cap screw. On Klean Kanteen, the screw is inside the bottle. On Hydro Flask wide bottles, the same screw is over the top.

When comparing both cap screw designs, it’s evident that Hydro Flask’s proposal is much better. If the cap screw is inside the bottle, it may easily deform with high impacts, causing leaks.

3. Available accessories

KK and HF also produce a wide variety of different accessories, to make water bottles much more practical and versatile. These accessories include cleaning kits, special caps and holders.

However, the durability of the materials used by both brands isn’t exactly the same. And in this case, Klean Kanteen is the winner, offering accessories made of stainless steel for maximum resistance and durability. This brand also offers metal cages that fit the frame of your bike.

4. Easy handling

In this case, we can declare a fair draw between both brands. Actually, there isn’t a big difference regarding ease of use between one brand and another. Most of water bottles are lightweight and easy to carry. To use them, the method is usually the same. You open the cap, pour the liquid, add some ice cubes, close the cap and you’re done.

So, ease of use isn’t such an important aspect that can determine your preference towards a certain brand.

5. Sealing

As said before, the way how you screw the cap of your water bottle determines its ability to prevent leaks. On Klean Kanteen models, the screw is inside the bottle. So, in the event of a high impact on the cap, the notches of the screw could deform, completely ruining the seal.

On the other hand, the cap screw of Hydro Flask models is on the top of the bottle. So, the high impacts are cushioned by the external walls of the bottle, protecting the cap screw. This results in a longer lifespan and a lower probability of leaks.

6. Color and shape

When it comes to water bottles, the difference in shapes and colors is also important. Comparing both brands, Hydro Flask certainly has a greater variety of products. The shapes and colors of their bottles aren’t the same in all cases.

Furthermore, Hydro Flask always surprises their consumers by releasing new limited edition bottles to the market.

However, Klean Kanteen has opted for a more uniform design in all its products. So, there are no noticeable color and shape variations between different models. In the past, Klean Kanteen also used to produce limited edition bottles. However, it’s been a long time since the last time that happened.

7. Ease of cleaning

No Hydro Flask water bottles can be washed with a dishwasher because the external coating tends to scratch very easily. However, some models from Klean Kanteen are safe for dishwashers, which is a big pro.

Cleaning a water bottle manually is very easy; however, it makes you waste time. Using a dishwasher machine allows you to invest that time lost in cleaning tasks in more important things. For that reason, Klean Kanteen is the best option in this case.

8. Capacity

Hydro Flask wide-mouth water bottles are available in a greater variety of storage volumes. For example, you can find 60, 40, 32 and 18 ounce bottles. On the other hand, Klean Kanteen bottles are only available in 20, 16 and 12 ounce presentations.

9. Price

Comparing the prices of both brands, it’s clear that Klean Kanteen gives you more storage volume for less money. For example, the cheapest KK bottle costs $30 and offers 20-oz of capacity. On the other hand, the cheapest HF bottle has the same price, but only gives you 18-oz of capacity.

The same goes for wide-mouth models. The cheapest Klean Kanteen model costs $37 and gives you 32-oz of capacity. On the other hand, Hydro Flask charges $35 for 24-oz of capacity.


Q. 1: Klean Kanteen vs Hydro Flask. Which one is better?

A. It all depends on the personal preferences of the user. However, it’s clear that Klean Kanteen is far superior in several respects to Hydro Flask.

Q. 2: Yeti vs Hydro Flask. Which one is better?

A. Hydro Flask products are by far better. However, it’s also true that Yeti water bottles are more durable and resistant to high impacts.

Q. 3: Swell vs Hydro Flask. Which one is better?

A. Swell bottles are better because they implement a more ergonomic design and are available in a greater variety of models.

Q. 4: Which are the best features of Hydro Flask bottles?

A. The outstanding features of Hydro Flask products are the design of the tap screw and the wide variety of shapes, sizes and colors.

As a kid I inherited the love for mountain bikes from my father who used to ride for weeks through the Colorado trail in the city of Denver. He had his gang, and I followed pretty much the same track.

Later on, my interest in biking grew more after joining the Enduro race back in 2013. My buddies and I also participated in the Downhill racing for the third consecutive year, and it’s been an amazing experience.
