The only kind of flask I’ve ever had is Hydro Flask, but mine have a one- piece lid. The smaller one (16oz) began to slightly leak. So I kept looking at the Hydro Flask and finally found the 16 oz one in Lupine. Well, drinking out of it, the first half of contents are fine, but when you get to the second half and have to tilt it more, it leaks like a sieve. I have tried and tried putting the lid together (3 pieces) with the directions and cannot get it not to leak badly. I would like to try another one. 16 ounce ( don’t really care about the color). I like the fit in my hand, but the bad leak is totally unacceptable. I wish my review was better; but it’s how it is.Patty Storm

I am loving my brand new hydroflask, the straw cap is definitely the best feature for me especially on long drives I can pop the straw and drink instead of having to unscrew a cap which is hard to do with one hand. The straw cap is also convenient because it doesn’t involve any head tilting or leaning back to drink. Perfect for cold drinks all day through hotter weather and keeps my coffee and tea warm for colder mornings. All around it’s a much better buy compared to Walmart and Amazon counterparts because it’s much higher quality and keeps drinks at the temperature you want for longer. Looking forward to buying more for family and friends as gifts this Christmas!

Terrible! Tried using and it snapped, now I cant use the extra straps coz i dont have the tool. You need to have a better designed customizer tool for extra straps. Very disappointed. And yes, the 12. oz wide mouth bottle i bought was a disappointment too, coffee/tea/water would only last hot/warm for less than 2 hrs, seriously?!?? You claimed it is supposed to stay hot for 12 hrs , it’ not even close. My LeCreuset hydration bottle does not even claim 12 hrs for hot water to stay hot …. but it stays hot for 20 hrs!!! This is not my first time to buy from you guys, I have 3 bottles i bought from your website.

It's perfect for what I needed. A small coffee tumbler with a simple opening mechanism and that it leak proof. It's not different than others, but I find it pretty also.The price is okay. It holds the temperature pretty well as described. The color finish is pretty resistant to scratches. It also easy to disassemble the lid to clean it.I like the handle. It's comfortable to hold and you can also clip it to your bag with a carabiner. If you need a silicone base protector, it's the Small size that you will need. I like the fact that you can buy the lid separately if you need to (in case it breaks or the smell can't be removed).I have been driving alot recently, so this is perfect for the cup holder. Just be aware that it holds around 350 ml. I personally think that ... MoreIt's perfect for what I needed. A small coffee tumbler with a simple opening mechanism and that it leak proof.

Just be aware that it holds around 350 ml. I personally think that this is a great bottle ( speaking for myself who bought too many bottle). The quality built is great.Nothing bad to say about it so far. The opening is big, so you can easily put ice and it also makes it easy to clean it deeper with a sponge.
I purchased the 40 oz Wide Mouth with Flex Straw Cap. Here are some great things about it. 1. The amount of liquid it holds is perfect for the days you decide to go on a hike with your friend but your friend doesn’t understand that you’re a couch potato and therefore the hike she does 3-4 times a week, is killing you, so the amount of times you have to stop and drink water to make it through… it definitely holds the right amount. 2. It keeps the water super cold, when you put in cold water and then put the container in the fridge! I’ve noticed the water stays cold for the whole day. 3. Easy to take apart and cleanThings I’m not so fond of, 1. The water container is heavy, empty. So it is even heavier filled. Just something to consider. 2. Doesn’t fit in cup ...

Doesn’t fit in cup holders, it would be great if the same size container was tapered on the bottom to fit into standard size car cup holders. 3. The straw spits when filled, (or refilled) and flipped open. So just be careful around phones/computers or other electronics as a bit of water does come out of the flex straw.Overall, I do love the water bottle and use it daily.
The lid does a great job of keeping liquids hot. To get this insulation, the lid takes a lot of physical force to open and take apart (really can't be used by anyone with any wrist or grip issues). It comes apart into 4 very hard to clean parts. You have to be diligent with a brush or bristle to get inside everything.If you don't put the orange rubber gasket in *exactly* right, it will leak. After about a year, my gasket is getting darker and darker from coffee.I would not recommend this lid due to maintenance and ableism implied in the force required to take it apart.
Could not be happier with the performance of this bottle. It keeps my coffee warm for hours and it doesn't leak at all, even when turned upside down. I had to watch the video a couple of times in the beginning to figure out taking apart the lid but once you get it it's simple. I really appreciate that I am able to easily take apart the entire lid, thoroughly clean all the pieces and not worry about mold growing under some tough to remove/reinstall piece. I take this bottle everywhere - in the car, in the store while grocery shopping, on travel. It fits perfectly under my single serve coffee maker. The handle makes it so easy to carry when I have my hands full with other things. I love this bottle so much I bought a second one for myself and seven more to give out as ...

My only complaint is that I wish you could customize the 16 oz size and that it was offered in special edition colors.
Love these! I bought two and customized them; one for my husband & I. We are very particular with the quality and functionality of our purchases. And we love our coffee! This coffee Hydroflask with the patented flex sip lid is amazing! I find it very important that the lid disassembles for cleaning purposes. And the steps are simple. The coffee itself stays HOT alllllll day like it was just poured before every sip. I haven’t tried anything iced but I’m sure it’s just as good. It doesn’t leak when you’ve got it tightened like it should. Mine leaked on me one day but I reevaluated how I had all the parts put together, and the problem was I didn’t tighten the lid enough (not too tight, just be mindful of the rubber gasket that seals it) It’s a good size, fits in all my ...

Though if I have the bottle boot it does not fit my ‘98 4Runner cup holders (it’s older and just smaller) but with the boot it fits perfect in my ‘14 Kia Forte cup holders. The price even with the custom add-on was not bad at all! Love love love.
I have several different sizes of these and I consider them to be the best. I'm picky about my hot drinks being hot and these keep them hot for 4 to 6 hours. Sometimes they keep my tea so hot I can't even drink it for an hour. The lids are leak proof. I used to be so opposed to this newer style lid with the handle, but I have come to love it. The only downside is I can no longer open it one handed. The whole lid is more difficult to operate especially when you have arthritis in your hands. I also wish they had more colors and patterns like the water tumblers which have become so popular now.
I'm so disappointed, should have listened to a review that mentioned how hard it is to get the cap off. This is my first hydroflask so not sure if this is an issue across the board, or just with this item. But it is literally impossible for me (or anyone in my household) to get the cap off. This has happened after only having it a few months. So I brought it to my family over the holidays to see who could open it! The only one who could was my brother...who does strength training every single day. Now mind you the rest of my family isn't weak, we just aren't focused on strength training. Unfortunately I don't see my brother all the time, so this hydroflask is now sitting in my kitchen completely unusable as I cannot get it open once again. My money is now wasted. I ...

I absolutely do not recommend this item.This also is extremely frustrating because it then renders this thing unwashable and runs the risk of growing mold. I try to add soapy water through the top and swish it around but I can never fully empty it without the cap completely off.
