Last Update: August 16, 2023

When it comes to thermo-insulated bottles, Hydro Flask and Thermoflask are certainly our top references. Both brands have gained the preference of many consumers due to their high durability, modern design and performance. However, which one is the best bike water bottle?

Certainly, opinions are diverse in the debate of Thermoflask vs Hydro Flask. Each option with its own pros and cons. If you’re looking for the best insulated bottle for you and you don’t know which option to choose, don’t worry. Today, we’ll explain you the main differences between both brands so you can draw your own conclusions.

Thermoflask Vs Hydro Flask: The Main Differences

Thermoflask Vs Hydro Flask Water Bottle

  • Design

Thermoflask has maintained the same classic design through the years. It seems the peculiar cylindrical shape of their bottles is part of their identity as a brand. Also, they have a quite limited color palette. The available sizes are: 64, 40, 32, 24 and 18 oz.

On the other hand, Hydro Flask has a more varied proposal of designs. The available sizes are: 128, 64, 40, 32, 18 and 12 oz. Each models is unique, to adapt to the personal tastes of different people. So, it’s evident that design is very important for this brand.

Also, Hydro Flask isn’t happy with distributing a standard single model like Thermoflask does. This is only one of the many reasons why Hydro Flask continues to be preferred by most consumers.

  • Price

Price is perhaps one of the factors that most concern buyers. For example, a single 18-oz Hydro Flask can cost $30 or even more. However, the product is worth every penny when you consider its high durability and performance.

On the other hand, for the same $30, you can get a pair of 40-oz Tayeka ThermoFlasks. But why? It seems ThermoFlask uses cheaper materials to make its products. Also, the external finish isn’t as eye-catching when compared to a brand new Hydro Flask.

For that reason, when it comes to price, ThermoFlask will always be the winner. So, if your main objective is to save money, there’s no better option than this.

  • Accessories

Despite of their higher cost, Hydro Flask products are more widely spread on the market in contrast with ThermoFlask. Due to their high popularity, it’s possible to find Hydro Flask products in a wide variety of sizes, colors and models. Also, you can visit the official website and create your unique model.

There, you’ll also find a huge gallery of accessories that far exceeds that of ThermoFlask. So, in terms of variety, Hydro Flask is clearly the winner.

  • Durability

Both Thermoflask and Hydro Flask are very durable. The inner container is made with the best stainless steel. Also, their wide base makes them less prone to falls. So, there’s no doubt that both products can last a lifetime with the proper use.

Also, both brands follow rigorous quality controls. So, you can be sure the bottles won’t lose their original resistance with changes in temperature and humidity. In the event of a fall, the liquid won’t spill as long as the lid is perfectly sealed.

With the time, the external paint coating may scratch a little bit. However, this change doesn’t alter the ability of both bottles to maintain the temperature of cold and hot drinks for longer.

  • Insulation

Although the price difference between the two products is quite evident, in terms of insulation, the final results are quite identical. Both Hydro Flask and Thermoflask use the same double-wall vacuum insulation system. Also, they’re made of the same material: 18/8 stainless steel.

You won’t notice the temperature difference if you pour the same liquid into both flasks under the same conditions. For example, after pouring water at 5º C into both products, the final temperature after 24 hours was exactly the same: 8.8º C. So, with cold drinks, seems that Thermoflask and Hydro Flask have the same performance.

On the other hand, things change with hot drinks. After pouring hot water at 65º C into a Hydro Flask, the final temperature after 24 hours was 37º C. In the case of Thermoflask, the final temperature of water was 35º C (considering the same conditions). So, Hydro Flask wins the battle by 2º C.

  • Lids and Caps

Despite of the great popularity of Hydro Flask products, their lids and caps aren’t the best of all. For example, they’re not completely leak proof. So, part of the liquid can end up on your shirt if you’re not careful when drinking. Also, the lids and caps aren’t dishwasher safe.

For that reason, it’s recommended that you wash your Hydro Flask manually to prevent scratches and other damage on the surface.

On the other hand, caps and lids from ThermoFlask are great to prevent spills. So, you can hold your bottle on any position without fear that the liquid will escape from the bottle. However, as in the case of Hydro Flask, they aren’t dishwasher safe.

In addition, all of them have the same black color. The only thing that differentiates them is a small label with the same color of the bottle indicating the brand’s name.

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.
