Thermos Intak 24-Ounce Tritan Hydration Bottle, Purple

I had one of these for years and the lid clasp broke when I dropped it on a hard surface. So when I looked for a replacement, I was happy to see the same bottle is still being made and sold. I've tried countless other water bottles, but they all had something or another I didn't like. This one is great for so many reasons: no leaks; easy to open with one hand; easy to hold; large enough hole to drink rapidly; visibility of water level; easy to wash; fits cup holders; pretty color! Just don't drop it lid-first on a hard surface.

I bought this because being a regular gym goer, I must intake a good amount of water throughout the day. In addition, by being in the military, I am encouraged to stay hydrated at all times. This bottle is the perfect tool to enable me to accomplish that goal. Also, I was fed up with buying and throwing away so many relatively expensive 1 liter "sport" designed bottled water bottles. I wanted to save money and my trashcan buy purchasing the cumbersome, albeit less expensive 1.5 liter bottles (hey I'm trying, environmentalists). I would've gone with the 5 gallon jug, but it is just too impractical to pour and it doesn't fit inside my fridge (or my trashcan).Design: This is a tall and slender bottle made of BPA-free plastic, with a fairly solid loop for attaching it to things (and vice versa), which fits in with many other styles on the market. For grip, it has a wide textured surface running down one side, which also curves slightly inward, allowing a more comfortable hold for smaller hands. On the reverse, it has a dual measurement scale in liters and fluid ounces. The liters scale goes from 0.1L by every 100 milliliters up to 0.6L, while the fluid ounces is scaled from 4oz by every 4 ounces to 20oz, although it can hold 24 ounces. The look is very interesting and unique, as far as plastic water bottles go.Performance: Well, I have very large hands and it is indeed comfortable to grip. I assume that the textured side is where the fingers wrap around to, but in any case, you can have it on either side, depending on how you twist the cap onto the bottle. Now onto the cap, which is this bottle's bread and butter. It twists off with ease, opening the way to the wide mouthed opening of the base, which allows for easy pouring into and for dropping in large solid objects, like ice. It has a silicon seal inside, so it stays put with no leaks when you twist it back on. The mechanism for drinking is by way of a large thumb button on the front and a flip-top lid. There is a thin metal latch that flips up nicely over and around the button so you don't have an accidental discharge of all your liquid inside your bag or on the floor. The bottle is touted as no leak because the flip-top lid has a silicon pad underneath which creates a seal on the "spout" when closed. In fact, the entire mouthpiece is covered, protecting it from the environment. Another useful gimmick added to the lid is a rotating dial on top which is there to help keep track of how many bottles you drink.Usability: First off, I've used many different hydration containers with all sorts of mouth pieces and I must say, I don't like putting my mouth on stuff when I drink out of it. The bite valve used on CamelBak's bottles and hydration pouches is pretty novel, but I not only have to put my mouth on it (leaving residue), but also bite into it, thereby grinding everything it is exposed to further into the valve and sucking up whatever is left. The squeeze bottles where the seal breaks when enough pressure is applied is okay, but they just aren't solid enough for me. Thermos finally has it right. The flip-top lid works exactly as it should. You press the button and it quickly snaps open and stays there, due to a small silicon band wrapped in a way that applies constant tension to the lid, but is easy to snap close with one finger. The mouthpiece is perfect for me because it is large (but not too large) enough for me to basically pour a steady stream of water into my mouth for quick hydration. The true test is when you aren't thinking about it like, say, when at the gym doing high intensity workouts. The mechanism was so smooth (open and close) that it did not interrupt or deter me one bit. As for the rotating dial, it takes more than you think to turn this thing. Being smooth plastic, you really must put some pressure on it to rotate it, even with the grooves. It is still functional to me.Overall, for my purposes, this is an excellent and unique design for a hydration bottle. Because there aren't many porous internal surfaces, you can put liquids other than water in there. But, not for long and you must rinse it out immediately afterwards, so I wouldn't recommend it. Just an FYI, if you do not care about the rotating dial, Thermos also makes a similar Under Armour version which has a slightly shorter lid and smaller thumb button. The bottle also seems to be made of slightly thicker plastic, so it maybe could survive harder crashes. I can't really say for sure. It is also slightly cheaper at $15.99 right now on Amazon, but only $12.99 in the PX for those in the military.

I love this water bottle. It's tough, doesn't leak and is easy to clean.

This review is of the Thermos Tritan bottle, mainly as it compares to the the Thermos Intak Bottle...I use a water bottle pretty much all day, every day. I bring the same one with me to work, then bring it home to use. I prefer drinking from a water bottle to a glass in order to prevent spills, and just because I like the way the right bottle drinks. Cleanliness, ergonomics, and durability are most important to me in a bottle.I have tried several different bottles over the years and the Thermos Intak is my favorite. I own several Intak's and wash them in the top rack of my dishwasher every couple of days. The down side of the Intak bottle is that, if it falls hard enough on the top, on a hard surface, the cap will break. It's not the end of the world since you can get replacement tops from the manufacturer for $4 a piece by just calling them. The ergonomics of the Intak bottle are fantastic. The opening is just the right size for drinking, the cap closes to keep the spout clean, and it also disassembles for thorough cleaning.I decided to try this new Tritan bottle because it looks a lot like the Intak bottle that I love, with some improvements. It is the same size in volume and is slightly shorter in height by maybe 1/4 of an inch, due to the more compact cap. From photos, I thought maybe Thermos improved the durability/breakability of the cap, which was my main complaint with the Intak and main reason for trying the Tritan.The redesign of the cap brings lots of improvements:a) More compact design which may be more durable. I haven't tried to deliberately drop the bottle, but it seems like it would hold up slightly better, although I can't say for sure. It's still not even close to indestructible, but nothing's perfect.b) The clasp and spring mechanism is improved over the Intak. It now uses a silicon rubber band to pop the cap open, whereas with the Intak, the cap popped open by compression of a small piece of silicon rubber. This change makes for smoother close and open, with a better feel to the mechanism. It also helps ensure the top opens all the way. I can see this silicone band wearing out after a while, but it looks easy and cheap to replace, as is the seal.c) The extra metal safety clasp is retained and is slightly easier to engage than the Intak'sd) The carrrying loop(typically used for holding the bottle with one finger) is improved as well, and its position no longer affects popping open the cap when you press the release button. With the older Intak, if you fold the hook down and try to pop open the cap with one hand, it won't pop open all the way (I noticed this only happens on some of my Intaks).e) The ring for counting your water intake is also a feature of the Tritan bottle. I never use this feature, but I noticed that the ring on the new bottle works just fine, although slightly harder to turn than the Intak.In addition to the improvements to the cap, the Tritan bottle is A LOT more grippy. This is very welcome since the Intak bottle could get a bit slippery when wet.Although the redesign brings all of these improvements, it brings with it a major detriment to its ergonomics: The spout is significantly smaller in diameter. It is also not angled, like the Intak's spout. I find that when drinking more than a sip, the Tritan's spout doesn't allow enough flow and causes air to mix with the water. It's not horrible, but it is not as comfortable to drink from as the Intak.This bad trait of the Tritan is really unfortunate, because it is better than the Intak in nearly all other ways.I just ordered 4 more Intak bottles just in case Thermos decides to discontinue them. I won't be ordering any more Tritan bottles, but am not going to totally stop using my Tritan either. I hope this review helps others in deciding on a water bottle. Obviously a water bottle is important to me, and I probably sound like a huge nerd. Maybe I am. What can I say?P.S. The Intak and Tritan bottles do not have ANY interchangeable parts.Edit: Due to breaking too many Intak tops, I now use a Nalgene Narrow Mouth 32oz bottles. These are very difficult to break, and have a higher capacity, and are not quite as top heavy. Other than those advantages, I still like the Intak bottle for the advantages stated in my review.

I love this water bottle. This is the second one I have purchased for myself, and my kids have them too. I love the spring loaded button, so I can operate with a single hand. It also has a locking clasp, so if I need to put it in my back pack with my laptop I don't worry about spills. It also has a loop to carry it, so when my hands are full I can loop it over a finger no problem. The bottle does "sweat" with cold liquids in it, so I keep a paper towel under it on my desk. It isn't insulated so the liquid won't stay cold, but I empty mine in a few hours so it doesn't matter. I used my last one every day for two years and the opening mechanism lost its spring and the finger loop broke, but for around $10 I got more than my money's worth. Buy it, you will love it!
