Hydro Flask Water Bottle - Insulated Stainless Steel - Wide Mouth Sip Lid, Non Spill, Leakproof in 16 Oz Black

-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've tried so many different types of water bottles from a variety of price points - flip top, straw, slide top, removable top. This is the only style I have tried that does not leak, does not break, keeps my drinks cold even in a hot car, and the 20oz is easy for me to carry around and use while on the go. The wide top easily lets me fill the bottle with ice directly from the fridge dispenser before adding my drink. The wide strap is easy to grip and the bottle fits in my car cup holder. The flex sip lid takes a minute to figure out when you want to take it apart to put the lid in the dishwasher top rack (the bottle itself is fine on the bottom rack) and reassemble when clean, but once you know, it's a 5 second process. I now have three of these great water bottles so I always have a clean one ready to go out the door!

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!

Great high quality water bottle! I had my last one for over 10 years but sadly lost it. This is a perfect replacement although I miss the simple old Hydroflask flip lid that was 100% leakproof. This definitely needs a different lid if I’m throwing it into my bag.

I'm very happy with this bottle, I got it on sale for $24 in the color Lupine and I'm obsessed. It's super cute, insulated, and high quality.I'll start off with what I dislike about this bottle, then move on to what I like. The lid is slightly annoying to clean because you have to take it a part and stuff. It's probably not their best lid, but it is kinda cool. Straws do not work with it at all. Also, the bottom part makes an awful sound when you push it on a surface.The bottle keeps ice cold overnight if you tighten the lid. Another reviewer mentioned that this isn't leakproof - mine is leakproof, IF you make sure you twist the top part of the lid all the way. The bottle is dishwasher safe, but I think technically dishwashing any bottle makes it less insulated. The handle is also very nice if you plan on taking it anywhere. The entire bottle feels very high quality in my opinion, but if it does break you can go on the Hydro Flask website on the "Let's go Promise" section to use the warranty and get a new one.Overall, I love this bottle - but I do think there are better lids.

I am absolutely thrilled with my Hydro Flask Wide Mouth Bottle (20 oz) with the Flex Sip Lid in black! This insulated water bottle has truly become my go-to travel cup and coffee mug. First and foremost, the no-leak design is a game-changer – I can toss it in my bag without a single worry. Even more impressive is its insulation power; my coffee stays piping hot for hours, and warm for even longer, which is exactly what I need for those early mornings or long days. The 20 oz size is ideal, and the sleek, compact shape fits perfectly into the side pocket of my TUMI backpack, making it an indispensable travel companion. If you're looking for a reliable, high-performing, and perfectly portable insulated bottle, look no further than this Hydro Flask! (P.S. Hydro Flask is cheaper than YETI and Stanley.)
