Hydro Flask Flex Sip Coffee Tumbler – Insulated Stainless Steel, Non Spill, Leak Proof Travel Coffee Cup 16 Oz White

-Important to Me- I was shopping for a leakproof 20 oz travel mug to use for coffee. I’ve had a Contigo West Loop for about five years but its trigger button doesn’t open far anymore and it will need to be replaced soon. I wanted to see if there’s a better option for me, so I compared the Zojirushi SM-SHE60BZ, Camelbak Forge Flow, and Hydro Flask Stainless Steel Wide Mouth Bottle. The features I like most in my Contigo are the trigger opening lid, the rubber around the lid for grip, and the overall size. However, the inside stains easily, the lid is nearly impossible to clean thoroughly without the using the dishwasher, and the trigger lock button also serves are an air hole so leaks if you don’t lock it. I'll use this mug to take coffee to work then for water throughout the day. I’ll fill the mug with coffee, throw it in my backpack and lay that on the car seat for the commute to the office, and keep the mug on my desk. I’ll also use this for water other times to take with me while I’m driving. I need this to be leakproof, keep coffee reasonably hot for a couple hours (I don’t like piping hot coffee, and I don’t have complaints about the Contigo), and be able to fit this in the fridge door recess for filling from the ice maker. I also don’t want the mug to make a lot of noise when I set it down on a table or my desk. I use adhesive felt on the bottom of my Contigo for this, but a built-in feature is nice to have. -Mug Size- The Zojirushi is the tallest and slimmest of all, so it will fit in the most cup holders, backpack sleeves, etc. The Hydro Flask, Camelbak, and Contigo are all roughly the same height with the lids on, the Contigo just about 1/8” shorter than the others. Lids off, the Hydro Flask stays about the same height with the Contigo then the Camelbak coming in shortest. The diameters are about the same across these three. Someone with small hands may prefer the Zojirushi over the others. All mugs fit in the recess for my LG water and ice maker but the Zojirushi just barely. I measured the opening because a larger opening is easier to use. I want to be able to fill the mug with ice from the fridge door, and pouring coffee from the pot is easier with a larger opening. The largest is the Camelbak, followed by the Contigo, then the Hydro Flask, and smallest is the Zojirushi. The Zojirushi definitely needed some attention to fill without spilling from my standard coffee pot. The Camelbak is the winner here. -Heat Retention- I filled each mug with 20 oz of water at 183.1 degrees F and let them sit for two hours. After an hour I did a touch test on the mugs, very imprecise, but I felt the sides of the mugs as well as the top and side of their lids. The Contigo mug was a bit warm on the outside. None of the other mugs felt noticeably warm but the Zojirushi did feel cooler than the rest; that could be due to the non-powder coated smooth finish though. The Contigo’s lid was very warm on the top and sides, warmest of all. The Camelbak lid’s top and sides were nearly as warm as the Contigo’s. The Hydro Flask lid was less warm than those, and Zojirushi lid was barely warmer than the air temperature. I’d imagine this will correlate to the amount of sweat that develops on iced drinks. All reviews indicated that the Zojirushi would retain heat best, almost to a fault. This proved to be true with a final temperature of 172.8. Next was the Hydro Flask at 160.7, then the Camelbak at 152.8, and the Contigo at 151.5. -Other Useful (and bad) Features- The Zojirushi has their proprietary Slick Steel interior finish intended to resist stains and corrosion. It feels smoother than the others so I won’t be surprised if it resists coffee stains better than the rest. The light colored plastic mouth piece and silicone stopper, though, will show stains more than black plastic of the others. The locking lid will prevent unexpected leaks if the button is pressed accidentally. The exterior finish is smooth and close to the Contigo. It also looks more modern compared to the others. It’s definitely the highest quality mug of this group. The Camelbak has a powder coated finish that is tactile and easy to grip, and a non-slip silicone base that makes it nearly silent to set down on a table. It has a trigger button for easy drinking but it does not lock closed so accidental spills are possible, for example if it’s rolling around in a backpack. The fixed handle on the lid could be useful depending on the person but would be an unnecessary feature if you won’t use it. It isn’t really detrimental, though, and does help stabilize the mug when drinking. The Hydro Flask’s powder coated finish is also tactile and easy to hold on to. There’s less chance of it slipping out of your hand and just feels nice, slightly better than the Camelbak. Its Flex Sip lid is a quarter-turn open and closed, so it will be difficult to accidentally open but less convenient than a button open. The Flex Strap on the lid could be useful carrying the mug but also rotates out of the way if you don’t want it. There’s a silicone boot accessory available that will reduce noise when setting the mug down on a table. -My Choice- I ultimately chose the Hydro Flask. It has the best balance of features I’m looking for. I’ve used it for a week now and I’m happy. The Flex Strap makes it easy to carry and the powder coated surface is easy to hold. I bought the silicone boot which fits well and makes it quiet to set on a table. The boot isn't perfect though: it makes setting it in a car's cupholder difficult and it picks up dirt.

I love hydroflask, they never leak and keep your stuff cold. I also love that they don't have lead, and mold won't grow under hidden rubber pieces in the lid because there aren't any (at least not in the ones I've bought). I will say that this particular one came with a lid that I honestly never use and it does appear to be a bit hard to clean, but that might be a user error on my part? I bought the hydroflask lid with a straw to replace it, because I prefer straws over sippy cup lids. It's nice that you can switch out lids seamlessly! I just wish I could have bought this with that lid to begin with, but I dont think they offered it at the time. Anyway, I've had several hydroflasks for many years and they're still holding up really well!

Edited. I contacted customer support. They sent me new seals and voila. No leaks, no drips. I love my mugs again. I will update the review if I receive a response from the sellers. I had 4 of these I purchased approx a year ago and loved them, unfortunately some of them went missing. Ordered 2 more and both of the lids leak. I've contacted the seller and done the warranty request. Once I hear back I will update here.

So many good things to say about this flask! It keeps my drink warm for hours, way better than my previous flask of another brand. The handle on the lid has turned out to be so handy. It does take two hands to twist the lid open (one hand to twist upper lid open, one hand tohold the lower part of the lid), which is not great when driving. However, it is definitely leak proof, andoverall, I love the size, I love that it fits in my drink holder in my car, I love the color… It’s great!

It’s a Hydroflask so the quality of the thermos itself is high and it’s a good size. It keeps my hot drinks very hot and ice lasts in it for quite some time. The lid though … sooo fiddly. Be warned when you’re washing it, there are more parts than you think that you need to clean. And it kind of has a weird taste even though I’ve washed it and used it multiple times. 😩

Love the light pink color. This water bottle is the perfect size to carry around or take in your car. I fill it with ice and water, and it stays cool. It's very durable and I haven't noticed any dents or scuff marks. I wash mine by hand, and it stays clean.

So I've had this product and many of theirs for years, and just recently I had some issues, probably a product defect on one, and then wear/tear/negligence for the other. First. There was visible rust on the seams on the inside, close to the opening, and then somehow, water got in between the metal layers. I never use any sharp objects to clean this, there's no dents or holes inside/outside, so I have no idea really how water got through. I did however have this bottle sit with water for maybe 4 months untouched, closed, in a room, but I don't think that'd cause the problem. Any case, I reached out to their warranty and after some pictures, they sent me a new one. So that's great! Second, their flex lid. I love this lid overall because it's hard to accidentally open, or snag, and all parts are removable to clean. The bad, is that the silicone ring that makes it leak proof is susceptible to mold/staines. What happened for me, is that I use it to drink coffee, with cream/sugar and the residue sits in the lid, so if it isn't cleaned, it will slowly affect the gasket. Eventually, black spots appeared on it. Bleach helped at first but later on, it didn't anymore. Once again, reached out to the company, a couple pictures, and they sent a whole new lid. Keeping it clean more regularly would save you from this problem. Same with the o ring seal, it can be taken out to clean.

Good coffee flask, the lid sometimes leaks.

Tous les produits de cette marque sont qualitatifs, aussi bon pour le chaud que pour le froid Le système du bouchon étanche est très bien pensé et le nettoyage se fait facilement

todo excelente

I don't like: Hot drinks burn you and there is no smoothness in drinking, The old version is better. I like: the quality.

I received it without box and cloth cover. Now I'm thinking if this is original....
