This is the perfect travel mug! It fits right under my coffee maker. Keeps my coffee HOT. Fits in the cup holder in my car. And the flex sip lid DOES NOT LEAK! If it does, you've assembled it incorrectly. Mine leaked after the first time I washed it because I had the rubber seal on upside down. After I flipped it over, NO LEAKS!

I have several Hydro Flask products and have been extremely happy will of them. In fact I was so pleased with my 16 oz coffee that I purchased a second one as a gift. Unfortunately flip lid has been replaced with thi flex sip lid. It is near impossible to put it back together after taking it apart to clean. Very frustrating!I?ve never had an issue with the original lid but this new one is very difficult to reassemble.

Meets the quality of my other Hydroflask vessels. I have not had any issues with a leaky top and if I'm not in the car, I don't put it on anyways. As always, the color is rich, it's well made, and coffee stays hot as long as I need it to.

This coffee w/flex sip lid blows my yeti tumbler out of the water. It keeps my coffee warm for hours, my coffee doesn't spill anymore, and I love the convenient carry strap! The 16oz is the perfect size as well!

I have a Hyrdoflask for water with a straw lid that is my jam. I literally stopped using all my other reuseable water bottles. So absolutely excited to have the 16 oz Coffee tumbler with the flex sip lid. This would be a 4 or a 5 star review but lately I'm finding that as I refill and reuse the Coffee tumbler throughout the day coffee starts to leak from the seam underneath the 'turn to open/turn to close and seal' top part. It has literally dripped coffee on my ties and shirts. It used to happen sporadically but it's happening more often. I clean it, take it apart and try to seal and reassemble as best but it keeps happening. I love love love Hyrdoflask....but this was kinda sorta disappointing.

Bought the stone color first. I was shocked and amazed at how long my coffee stayed hot! So I bought a black one! Well.....for some reason, the black one doesn?t keep my coffee hot. I was sadly disappointed, and I even tried swapping lids with my stone color one to see if it helped. No bueno! I was excited to have a second one. It was a let down for me, as I?m serious about my coffee! Then I ordered the watermelon color. Coffee stays hot as long as the stone grey one!! I have no clue why the black one is so different. The other two keep my coffee hot for hours upon hours!. I even added my favorite stickers to my hydroflasks, because these are the best I?ve found for my coffee! Not to worry, I won?t cover up the logo. I want people to ask where to get the flasks!

Just purchased these after having the water bottle a few months. I like the functionality of it, my only criticism is the lid... taking it apart and reassembling isn?t easy.

I love the colour, the size and it keeps my tea hot for my entire work day! The only thing I dislike is the lid. When washing mine is quite hard to twist open and pull apart which means it takes a bit more time than I would like. I would probably prefer a lid I can quickly rinse under hot water, rather than one with different pieces. But in saying this the lid hasn't leaked, which is great!

I can deal with warm coffee and I do not like cold coffee. This 16 oz. coffee with flex lid has quickly become my favorite because it keeps my coffee piping hot (think scalding hot... which is exactly what I wanted.

We have purchased Hydroflask exclusively for all our insulated drink holders as well as buying the backpack coolers. This coffee flask just adds to our collection! Love the design of the lid, especially with the handle! Keep putting out great products for your customers...and we will keep adding new items!!!!

I bought this product because I am very happy with our wide mouth water bottles. The coffee bottle is so good that when I put hot tea in it, I have to wait more than 2 hours before I can comfortably drink it. It's easy to clean and the drinking cap is great. 5 star product for me.

I love this commuter cup. It's super durable and keeps my coffee warm for hours. I've used it everyday since I got it and it looks brand new.

I work as a nurse, and I use the regular bottles for my water so I figure I'd try this. Since it can be hectic I tend to not be able to drink all my coffee warm by the time I get to it. This has been working great for me and keeping my coffee hot (almost to hot- Definitely on my gift present list for friends and family now.

I got this to replace another coffee tumbler. I love Hydroflask water bottles because they really keep my water cold for hours!! This coffee tumbler has kinda disappointed me :( it was only hot for a couple hours .... more like keeps the coffee warm for hours. I dunno. I was expecting HOT when the description said hot or else I wouldn?t have bought it.

When it comes to enjoying coffee on the go, there is no better option out there than Hydro Flasks' updated Coffee Flask with Flex Sip Lid. Coffee stays piping hot all day long, and cleanup is a breeze with the new lids. This bottle from Hydro Flask checks all the boxes for me, and is definitely my most used Hydro Flask.

Really love this coffee cup. Its a great size and keeps my coffee warm after I come in from a long surf. I think there is room for improvement with the lid. But other than that it's a fantastic product.

I bought this for easy transportation of my hot beverages as I am on the go to school and work...and really just life. The lid began to leak the first time using it but only with hot beverages, weird right? Anyway, I contacted customer service and they sent me a lid, free of charge. That lid works perfectly. So overall, this is a great buy.

I am a bit on the fence about this mug's ability to keep coffee warm. To be fair, I contacted Hydro flask to get the specs and how much heat should be retained over a given period of time. I am no mug expert, but math and analytics are my area. I have called three times and only one of the people I spoke to even had a clue what I was asking for. They would simply repeat that the product would keep liquids hot all day. Finally I emailed them and still no response. I think they now just find me annoying. Call me crazy, but if I made a product designed to keep things warm, I would have a QC standard like percent of temperature lost over a period of time.

Product itself is excellent as usual, there are well over a dozen Hydroflasks in my household (two adults, two kids) and this is the first time I've been frustrated by a product. The leaky lid....the complicated lid....hopefully future iterations aren't this bad. I often find myself grabbing the ol' beat up 18oz cup with flip top lid.

Keeps my coffee hot for hours! Fits in my car cup holder. Doesn?t spill or leak! Fits in my hand, most do not. Stop wasting your money on others! I?m done! This will be my go to place for water and coffee bottles now!

It is good to keep my iced coffee cold for 8 hours. However, it's not good for hot beverage. It cannot keep hot coffee over 1 hour.

Had a another type first - lid was complicated and leaked if assembled incorrectly. Hydro Flask is much easier to remove and clean. Other one also lost insulation after just a few months. Lifetime warranty gives me confidence this one is better that way too.

I just received this in the mail and used it for the first time. Oh. My. Gosh. Love the size, handle, color, and that it keeps my coffee hot for hours. I’m picky about the temp of my coffee. Can’t wait to buy another.

I had the old-style lid with another coffee flask that I own and really didn't have much complaints about it. But when it was accidentally left behind someplace, never to be seen again, I decided to buy this one with the new-style lid. Not only is it absolutely leak-proof, but it's much easier and smoother to drink from, as well. I absolutely love it. I found it difficult to take apart at first, but watching the video helped and now it's easy.
