Hydro Flask 20oz bottle.

We just went on Vacation to Alaska. Each of us have this Hydro Flask everyday. It's a perfect size. Keeps whatever we are drinking hot or cold. Does not leak while being attached to the bottom of my sling. It kept ice overnight. Great price, great drink bottle.

Best travel mug
I really like using this as my daily coffee mug, whether I'm staying home, going to work or traveling. It fits in my single cup coffee maker (the 20 oz version wouldn't, but I would certainly brew in another cup and transfer into the 20 oz if I had gotten it). My coffee stays the perfect temp as I go about my day - commute to work, attend meetings. I like the handle, especially since I carry a lot every day. I can easily carry my coffee Hydroflask and large water Hydroflask in one hand. The lid needs to be disassembled every day to clean all the components so it can be fully cleaned. I typically rinse the cup at work and clean it at home. After 6+ months, it's still great! The lid was stuff the first couple times I disassembled it, but it has gotten easier. Rotate the top pas/ the red zone, and separate. The red gasket easily separates, and the remaining plastic rotates out of the lid base. Reverse the order of steps to reassemble. I also had a leak within the first couple times I cleaned the lid. Ever since, I have taken an extra second to ensure the gasket is nestled into its place, and no more leaks. ... show more

Great tumbler
Color: CASCADE Capacity: 473.176 milliliters
I like the size of the tumbler but the lid is hard to put together after washing so I replaced it with another lid instead. Great tumbler for holding cold or hot liquids.

Lid is amazing! Actually works!
Color: Reef Capacity: 591 milliliters
I love this coffee tumbler and I especially love the lid! Now that I have the hang of how to put back together, which is unbelievably easy, I want another but it looks like the lid situation changed?? It's so easy to take apart and just as easy to reassemble -- way easier than I expected. The entire process is a step by step reversal of disassembly, which is printed on the lid parts! Fingers crossed this lid regains popularity because it's friggin genius! ... show more

Great except the lid
Color: Aloe Green Capacity: 20 ounces
Love the size, the color, and it keeps my drinks hot or cold which ever I put in it. What I don’t like is the lid. It leaks a little when you shake it up to mix or sometimes when you drink from it. Not a lot but it’s annoying. It’s also very difficult to clean. I use power mixes in it often and it very difficult to clean it. I don’t like the other option of the pop top with a straw. I like to drink it not slurp it thru a straw. I wish there was a different option for tops. ... show more

Keeps my coffee warm for hours. Very well made and I love taking it on walks with me. Lid is a little irritating to clean, especially when you drink coffee. I have to rinse it out each time. Also, the coffee taste won’t leave the cap, even after cleaning. Still a good bottle that does everything I need it to. ... show more

Almost perfect
Color: white Capacity: 473 milliliters
I typically use an Owala or a Yeti for my daily water bottle. I've tried different sizes and lids of both Owala and Yeti, but this is my first Hydro flask and first bottle with a twist to open cap. I was skeptical of this purchase because many reviews said it leaks and I throw my bottle in my bag often but I decided to buy this because the 16fl oz white was on sale for $16 and I couldn't pass up that sale lol. As soon as I got this bottle I put water in it and shook it as hard as I could, no leaking. The next day when I put some ice coffee in it and turned it over it did have a few drops come out. If you're someone who brings their bottle with them everywhere and enjoys the peace of mind of being able to throw it in a bag without leaking, I would pass on this one. This bottle does an amazing job at keeping stuff cold for a long period of time, but the possibility of leaking is a deal breaker for some. It's pretty easy to clean although I prefer bottles without a rubber gasket since they are easier to get moldy and this one has two in the lid. Regardless of the flaws, this bottle works for my intended purpose of carrying juice or ice coffee with me to work. ... show more

Keeps my tea hot for a loooong time. But at a price.
Color: Surf Capacity: 20 ounces
I really wanted to love this bottle. The size and shape are great. The handle is comfortable, and the insulation is incredible. I drink hot tea at work, and even after several hours it's still almost too hot to drink. It easily keeps my tea hot longer than it takes me to finish it. But there's one frustrating design flaw I just can't overlook. When the lid is on, steam seems to condense and collect around the inside lip where the lid meets the bottle. Every time I take a drink... drip. On my shirt. Drip. On my pants. When I unscrew the lid, there's usually a small pool of tea sitting around the inside rim. I have to wipe it away, screw the lid back on, and eventually it builds up again. Sometimes I remember to wrap a paper towel around the bottle before taking a sip to catch the drips. Most of the time I don't, and I end up wearing my tea. It's a shame because everything else about this bottle is excellent. If it didn't have this issue, it'd easily be five stars. Instead, I'm seriously considering retiring it to the pantry and buying something that may not keep my tea quite as hot but also won't leave my clothes spotted every time I take a drink. Great insulation. Great build quality. Frustrating drinking experience. ... show more
