    • It's a Bottle. It Holds Water.
Style: 40 Oz Color: Fir
The water bottle works great. It keeps water chilled rather well. If you're in it to save some plastic, great! It'll last you a long time. If this is your 5th one, I think it defeats the purpose of being "green." But that's a different conversation. How cold does it stay? Long enough. If you want it to stay cold 12-24 hours, that also defeats the purpose. Drink your water. Why do you need your water to be cold tomorrow? Drink your water today. What I love about this compared to other bottles I've used before or seen: * Wide Mouth - easy to add ice. Easy to drink out of. Easy to clean. * No Straw - no concern about getting Smoker's Lines. * Size - some other bottles of the same external size are about 32 oz vs. 40 oz. * Handle - Fun to swing. * Doesn't Spill. ... show more

    • Amazing water bottle!
Style: 32 Oz Color: Fir
I absolutely love this water bottle. Drinking out of it is so nice and crisp feeling and the water stays very tap cold (or fridge cold if you prefer). I'm so happy to have a water bottle again and it's super nice to have an insulated metal one because now cold will stay cold and if I happen to have tea in it, that will stay hot :) I'd give this 10 stars if I could. ... show more

    • Better than the Former Version
Style: 20 Oz Color: Moonshadow
My Hydroflask from 2019 finally gave up the ghost, after I had repeatedly banged it on the bottom. Finally bought a silicone boot, but it was too late for the old bottle. This new one seems better designed, especially near the top. And it's wearing the boot, so it won't get banged up! Works like a charm, keeping ice for as long as 24 hours. ... show more

    • Ice melts overnight but water does stay cold.
Style: 20 Oz Color: White
For what it is, it works. Originally, I accidentally bought a couple of lids for this brand of water bottle thinking I was buying for another brand, due to the way the searches work here on Amazon, and held on to the lids until it was too late to return them. Then I eventually bought this bottle to match the lids. This bottle is a little smaller than the one I had, but that's just the size I chose, mainly because it was the cheapest. So, being smaller, obviously it doesn't hold as much water, but it does hold water and the lids I bought fit nicely. The main thing I'm not quite so fond of on this bottle is the insulation. With my original water bottle, I can put in ice cubes and water and the next day I'll still have plenty of ice in the bottle. Not so much with this one. The water WILL be cold, but the ice will have melted, so that tells me it's not quite as well-insulated as the other one, but maybe that's due to the smaller size. Other than that, it works nicely and has managed to fall and hit the ground a time or time with minimal damage. Overall, it's a good water bottle. ... show more

    • Excellent Thermos
Style: 20 Oz Color: Dew
This thermos has become my go to for EVERYTHING liquid! It’s the perfect size (easy to hold with one hand). It has a great carrying handle on the lid, it keeps ice for a few days if left undisturbed, easy to clean. I have detected no strange smells (I wash it with a bottle brush after each use). I will say be vigilant when cleaning the inside of the lid as buildup can occur. I fold a paper towel several times with an angle and swipe around the inside a few times to clean. ... show more
