Looking for a stash-and-go insulated water bottle that's as easy to carry as it is to love? The 12 oz stainless steel insulated Hydro Flask water bottle is the right choice for those looking for a smaller insulated bottle that performs as well as the big boys.

Best little water bottle ever!!!!!

I adore this thing, and I never thought I would feel that strongly about a water bottle! I got mine thru a third-party site and didn't realize it was for hot beverages, too, so once I discovered that, it really became my favorite thing that I owned! I take it with me everywhere and I find it's a much more livable size than bigger water bottles. It keeps my water nice and cold all through a hot yoga class and my hot chocolate HOT even hours later on an icy day...and yet its small, thin and always perfect to the touch. There are few things better than finding something so simple that is SO well designed. Thank You!

Classic Stainless 12 oz. Standard Mouth Small Bottle Hydro Flask.

I like the portable size of this Hydro Flask. If my hands are full or I get tired of holding it, I can easily put it into mu pocket.

Needs a flip lid

Only thing that would make this better is a flip lid for coffee. Whether that be a new flip style lid that works on the standard mouth or a wide mouth version of this. If either of those came true I'd buy several more.

Need the 12oz in Wide Mouth

Love our Hydro Flasks, I think we have purchased about 6 of them. However, Hydro flask really needs to make a wide mouth 12oz flask. That would be the perfect size for coffee and tea and the wide mouth flip flip lid is the only lid that really works with hot coffee or tea. I can guarantee that we would buy at least three more Hydro Flasks if only you had the 12oz wide mouth.

Best Water Bottle Ever!

I love this product, I bought one for all my kids. Keeps the drinks cold all day which is good for my kids because they prefer cold water. They drink more water because the bottle keeps their drinks cold. Why not 5 stars? Because the bottles are easily dented, especially since my kids use them. Maybe if there was a protective rubber sleeve to go over the bottle? This way there could be different designs.

Amazing insulation

I purchased one of these at a visitor center in Yellowstone. I mainly got it to keep drinking water cool, during my trip. This week I went camping. One morning I made hot chocolate in my Hydro Flask. The insulation on the flask is amazing. There was absolutely no heat transfered to the outside of the flask. It remained cool to the touch.

12 oz is perfect size...

I love this!! How many times am I drinking my coffee, but need to hop on the bus? "Sorry miss, you may not bring that beverage onboard." No more!! The 12 oz. bottle is perfect size to throw in my bag, especially since it is so lightweight. Really, we have no excuse to pollute the environment. And I especially love the 5% to charities program. Nicely done, Hydro Flask!

the best

This is my constant companion. I carry it in my purse when I am out and it keeps my water cold all day. At night I fill it with ice cubes and than water and put it on my nightstand and in the morning I still have ice cubes. No more water bottles for me. I just carry my flask. Good for me, good for the environment.

Seems to defy physics

I usually bike in the summer nights for 2-3 hours in 30-34C (92F+) and wanted to stop spending cash on expensive sports drinks at a vending machine that would be ice cold at the end of my ride. It also fits neatly in the water bottle cage, so decided to give it a shot. Well this thing just plain works. I stuck 3 ice cubes in the bottle and for the first 5 minutes of my bike ride all I heard was this clunking noise. I thought something had broke in my bicycle. Turns out it was the ice cubes bouncing around the bottle! For remainder of the ride all I could hear was the ice bouncing around, it was actually kind of hard to hear whether or not my gears were shifting. And yes, 3 hours later, the sports drink which I poured at home was ICE COLD. Totally worth it, and looking for reasons to buy more! All products should be of this quality!

the perfect small drink carry along....

Fits in my backpack side pocket. Hangs from the hook on my travel bag. Fits in my cup holder. It's basically the size of a canned drink, but you don't throw it away, it stays cold for 24 HOURS (it really does -- ice was still there a day later) -- and it doesn't weight down whatever I'm carrying. Just a handy drink whenever I need something to keep from getting too parched. Just right for a canteen-type carry-along. (and they make a sports-bottle cap that still has the loop to hang, but lets you drink without removing the lid completely -- one handed drinking in case you're on a walk or bike ride.

don't need to say a lot

I feel I don't need to say a lot. Everyone who use this product will think it is good. I go to school everyday with it and it keeps cold drink cold, hot drink hot. Once I put some boiling water in it, I have to leave the bottle open for a long time before I can drink it. And the amazing thing is you can't feel hot at all from the outside. Great bottle. Great value. Great color!!!

Really works!

After some research, I bought four(4) of these HydroFlask bottles in different sizes more than a month ago. I was looking for stainless steel bottles (for water) that kept things cold for more than a few hours and that didn't sweat. I am VERY happy with these bottles. They keep the water cold, and they really don't sweat at all! We live in the Caribbean, and I have left my bottle in the hot car for several hours - to come back to find ice in the bottle and no sweat(condensation). GREAT! I am watching to see how the paint finish and the bottles themselves hold up to the battering at school (with a 3 year old) but so far so good. They are pricy, but I think it's worth it. Will definitely be looking to buy these again as we grow our s/s water bottle collection.

Great Insulated Water Bottle

This is a great water bottle that is insulated yet still fairly light-weight. We have two now, and they have held up much better than our other stainless steel bottles.

Keeps drinks cold, but need flip top

This bottle keeps my stuff cold for 24+ hours. This would be a 5 star product if it had a top that could be opened with one hand.
