This is a plastic bottle with a flip cap and a relatively small capacity. The bottle is too small to be useful on hikes, especially out in the New Mexico desert, where we did our testing. The Intak is better used indoors, as a bottle that can accompany you to the office. The bottle comes with a meter on the rim so that you can record the number times you've refilled it — making it good for those who are trying to up their hydration! The flip cap is secure, but a bit over-built in our minds.
Thermos Intak 24 Review
Cons: Overly complicated lid design, small capacity, lacks durability
Compare to Similar Products
Our Analysis and Test Results
Due to its mostly plastic components and relatively small size, the Thermos Intak 24 received slightly lower than average scores in our metric comparisons. The lid is complicated and difficult to clean and the plastic bottle and lid components make it less durable than others. The Intak received its highest score in our weight metric because of the materials used in its construction. Overall, this is a bottle that is best suited for indoor use where it can be refilled often.
Ease of Use
The Thermos Intak 24 has a similar flip-cap design to the Avex Brazos Autoseal and the new Platypus Duo Lock. All of these bottles have a latch or button feature that opens to a small drinking spout in the top of the lid. This design is useful since you don't have to take the lid off every time to drink. That said, it makes the bottle more complicated to use. We found these lid options to be novel, but not necessarily that much more efficient than a traditional bottle, like the classic Nalgene Wide-Mouth.
The lid and flip-cap closure mechanism on the Thermos Intak is the weakest link in terms of the durability of this product. There are two flipping clip loops that are plastic and seem likely to break off after lots of time in use. Much like the Contigo Thermalock Glacier, this water bottle has lots of plastic parts in its lid system that lowered its overall durability score. We found that bottles like the Yeti Rambler 26 are much more durable because they are simpler with respect to design.
Ease of Cleaning
Again, the many parts that make up the lid of the Thermos Intak make it difficult to clean. That said, the mouth of this bottle is wide enough to clean the inside easily, so that puts the Thermos up a notch against small-mouth bottles like the Soma or either of the collapsible Playpus bottles. One of the easiest bottles to clean was the Yeti Rambler 26 because of its wide mouth and height that allowed us to get to the very bottom fairly easily.
The Thermos Intak gets high praise regarding weight in our side-by-side comparisons. This bottle has a relatively small capacity, only 24 ounces, but this means that it is also lightweight. At 6.72 ounces, this bottle compares to CamelBak Eddy and the Nalgene Wide-Mouth in terms of weight. These bottles do have a larger capacity, though, which makes them better choices for hiking. The Intak is a good bottle to use around town where it can be refilled frequently.
Much like the Nalgene Wide-Mouth and other BPA-Free plastic bottles, the Thermos Intak does retain flavors to some extent. Plastic, unlike glass and to a lesser degree metal, tends to hold flavors for longer. That said, we were able to rinse the bottle out and remove flavors from the Intak without much trouble. The lid, with all of its nooks and crannies, is where flavors will hide since it is the most difficult part of the bottle to clean. A glass bottle, like the Lifefactory Glass Flip-Cap is a good option if you are concerned about taste.
This bottle is designed to help you keep track of your daily water intake. The Intak has a sliding dial around the lid that is numbered to remind you how many bottles you have drank each day. For folks that are interested in keeping better track of their hydration, or have difficulties drinking enough water, this bottle could help you out! Its small capacity makes it a good option for work or school — somewhere where it can be refilled with frequency.
Sold online for as low as $13, the Thermos Intak is a bottle of very good value. It is relatively simple and has a low volume, so it makes sense that it does not cost all that much. If you are looking for a basic bottle with a few features, like clip loops and a button opening mechanism, then this bottle is a good choice.
The Thermos Intak is a small capacity bottle designed to help you monitor your water intake throughout the day. It has a complex lid that can be difficult to clean and can sometimes retain flavor, but the price is right on this bottle if you are looking for something basic. We found the bottle to be easy to use, but a tad overly complicated as a bottle we used in our everyday.
