Thermoflask vs Hydroflask

When it comes to their primary purpose, keeping the liquid cold/warm, both bottles have been proven to be very effective. They are both effective during summer, and winter, so they can be used all year round for multiple purposes. They function on a similar principle, and they are made of the same material (stainless steel), so that is no surprise.

Both have double walls, and they are vacuum insulated to protect the temperature of the liquid inside. Some of Hydroflask bottles have the advantage of having a unique honeycomb design that maintains the temperature of water even longer, but the difference is not very significant.

They come in different sizes, and Hydroflask offers some extra-large size for people who need a water supply for a prolonged period. Both of the bottles are highly practical and easy to maintain. They have a wide mouth, and they are easy to clean.

The most significant difference is their lids. Hydroflask has more options you can choose from. There are three different kinds of lids that are described in detail later, but you have to decide and opt for only one of them. With Thermoflask, on the other hand, you get two types of lids: a chug and a straw.

Hydroflask is probably a better choice for people who are already experienced with these kinds of bottles and know precisely what they need.

Thermoflask is a better choice for people who want to use one bottle for various purposes, or they can’t decide which lid will suit them best before they try both of them.

Also, both bottles can be used by children. They are safe and free of toxins. Kids love them! It seems that the best way to motivate your kid to drink more water is to buy one of these bottles. Of course, they are very convenient for adults too, and you can use them on every occasion. They are perfect for carrying your water with you to work or while doing errands, but they can also be taken on hikes, snowboarding, or to the beach. Every family needs to have at least one of these bottles.

Both bottles are durable and beautifully designed. They look somewhat similar, and the primary difference is in details such as the logo or their lid. Hydroflask has a higher price because they are a well-established brand with a lot of experience and satisfied users. Thermoflask has a similar price as the other bottles of this type and this quality.

Thermoflask

Thermoflask is a beautifully designed, stainless steel water bottle. It comes in four sizes: 18 oz, 24 oz, 32 oz, and 40 oz. You can choose a color, from an elegant white bottle to the neutral black. There are also two shades of blue color, and it can also come in purple color. The bottle is powder coated, and it is pretty resistant to dirt and scratches, which makes it pretty convenient for this kind of multi-purpose bottle.

It has a double-wall made of 18/8 Food Grade Stainless Steel. It is made of high-quality material to ensure that it will not become rusty. The material is BPA ( bisphenol A) and toxin-free. The double-wall ensures that liquid inside this bottle can maintain the same temperature for hours. It can keep your drink cold for 24 hours, while it can keep your beverage hot for 12 hours.

This means you can use the same bottle during all seasons: in summer, during hot days, when you need your water to stay cold and refreshing, and in winter, when you want to have hot tea or coffee to keep you warm.

The Thermoflask bottle protects the temperature of your drink, and if you fill it with ice water in the morning, the water will stay cold until the next morning. If you add a lot of ice to your drink and then check on it 12 hours later, there will still be some ice, and it is carefully designed to prevent condensation.

It was designed with a wide top, on purpose, to make adding ice and cleaning the bottle easier. It is also effortless to clean any potential stains.

The most significant advantage of the Thermoflask bottle is that it comes with two types of lids. You will get both chug lid and straw, so you can choose according to your needs and easily switch between the two of them. The design of the chug lid is very innovative, and it is leak-proof, which is probably the most important trait!

Either way, both lids are easy to drink from, and the bottle weighs 1.3 pounds, so it is easy to carry around and very convenient.

Pros

  • Leak-Proof
  • BPA Free
  • Two lid variations included
  • Powder coat finish is sweat-proof, and resists dirt and scratches
  • Keeps hot drinks hot for up to 12 hrs, and cold drinks cold for up to 24 hrs
  • Wide mouth for ease of cleaning

Cons

  • Larger sizes don’t fit in cup holders
  • May leak around straw if not closed properly
  • Straw lid may be difficult to clean
  • Hand wash only, not dishwasher safe

Hydroflask

Hydroflask is bottle made from stainless steel with double-wall vacuum insulation. It comes in multiple sizes and colors. You get to choose the size as well as the type of lid. This bottle is available in the following sizes: 18 oz, 32 oz, 40 oz, and 64 oz. The largest size is perfect for occasions when you won’t have access to fresh water in an extended period, for example, when you go on a very long bike ride or even hiking.

Hydroflask is made of 18/8 pro-grade stainless steel, and it is very durable. It keeps water cold for up to 24 hours, and it can keep it hot from 6 to 12 hours (depending on the model). It has a wide mouth, perfect for adding ice and maintaining the bottle clean.

You can choose from three types of lids that are all compatible with the wide mouth of the bottle. Here is a short description of each kind of lid, so you can decide which one suits your needs the best.

Wide Mouth Flex Cap

Hydroflask Wide Mouth Flex CapThe wide mouth flex cap is perfect when you have to carry the bottle with you and make sure it won’t leak. It is made for biking and all kinds of sports activities. It is very convenient and helps you to stay hydrated during physical activity. The biggest advantage of this lid is that it comes with special honeycomb insulation inside the lid, installed to enable additional temperature control. This means the temperature of your drink will not change no matter what are the conditions outside, whether it is freezing or hot like in Sahara. It has a flexible strap, which makes it very easy to use.

Wide Mouth Straw Lid

The straw lid is perfect for sipping your favorite drink. Unfortunately, it is not intended for hot drinks, and it is not leak-proof, which may be its most significant disadvantage.

Hydro Flip

Hydroflask Hydro FlipAs its name said, with this lid, you can simply flip and sip! It is more practical than a straw because you can carry hot liquids inside and enjoy your tea or hot chocolate outside. But it has to be mentioned that this lid is also not leak-proof, causing many people unpleasant and uncomfortable situations!

Hydroflask offers a lifetime warranty, so you can easily replace the parts that are not functional and get the new ones.

As you can see, the characteristics of these two bottles are very similar. Customers were very satisfied with both of them, and neither failed to do their primary purpose, to keep the liquid stored inside hot or cold.

The only things customers complained about is the quality of the Hydroflask straw and the fact that Hydroflask lid with a straw leaks a lot. Although the brand clearly stated that that could happen and that the straw was not leak-proof. On the other hand, Hydroflask bottles with wide mouth flex cap may be the perfect solution for active people and those who practice sport.

Pros

  • BPA Free
  • Powder coat finish
  • Variety of different lid styles available
  • Keeps hot drinks hot for up to 12 hrs, and cold drinks cold for up to 24 hrs
  • Wide mouth for ease of cleaning
  • Limited lifetime assurance against manufacturer defects

Cons

  • Straw lid and Hydro Flip lid are not leakproof
  • Heavy, and may be awkward if you are on the go
  • Hand wash only, not dishwasher safe

The Final Showdown

It is difficult to decide, but since there are no vast differences, we would recommend Thermoflask because it is a good quality for money and it has everything a bottle needs. Of course, only you know what your needs are, so you should consider your priorities. It is also important to know when will you use your bottle and how are you going to carry it around. Those factors may seem insignificant, but they can help you decide.

Whatever you decide, it is important to use your bottle regularly and to stay hydrated. Those bottles serve as a great reminder that we should be all drinking more water.
