Hydro Flask 40oz. Wide Mouth Water Bottle

have several of them keeps my drinks cold all day

Bought this primarily for the 40-ounce size. I can fill it to the top with ice cubes, then dump in a 17-ounce bottle of water and it fills perfectly. I refill several times during the day and am constantly opening /closing. Twelve hours later I still have to run hot water into it to get the ice out. This thing is unbelievable! My wife just tested it out and was surprised---had to order her one. Well worth the money spent. I don't normally say that too often anymore.

This is the best water bottle i have owned. It keeps you cold drinks cold all day, perfect for summer and any desert hikes, and as well keeps you hot drinks hot forever. As we all know its pretty awesome when hiking in the desert and you have ice cold water but honestly I used this product more in the winter keeping my tea warm for all day backcountry skiing/snowmobiling. Overall this is a must for any outdoor enthuses, or anyone that works/plays in hot weather.

If you plan on buying 1 you will for sure have to buy 2.. a family member, significant other, co-worker, dentist, mailman, local bar tender, cat or dog, even your sweet old grandmas will want and need and steal your bottle.

This happened to me!
But no fear, I just hooked up each brother and sister, mom and dad with one of these sweet puppies.
40 oz of cold fresh protected water. They are perfect for night stand table, backpack, car camping! This one specifically will not fit in your average car cup holder but we offer PLENTY of other sizes, shapes, colors.
The options are endless.
This will not be my last purchase from Hydroflask
Don't be a victim of water bottle theft, just hook your family up and save the world a little with a re-usable bottle.

Leonardo DiCaprio will thank you for helping save the world.

Perfect water bottles. Keeps cold forever. I haven't done anything hot, I'm not a coffee guy. I have had ice last for 2 days while sitting in my car(during winter so that would add to the time). Easy choice, get one.

This water bottle is by far the best bottle out there. Keeps cold things cold and hot things hot!

It's easy when a hydroflask keeps your liquids hot or cold as you prefer. It's durable too.

Does the job it was purchased for. Keeping beverages at temperatures that I put them in the bottle.

Would Buy again 5/7

This is by far, and I mean by far, the most dependable water bottle I have ever used. It keeps your ice cold for days, hot water for days as well. I am downgrading this a star for the cost and the weight. It is pretty spendy for a water bottle at $40 + bucks, but it is pretty rugged, which is great for the back country. It is heavy. You can get holders for the bottle, but then you are looking at a total of $70 plus for the total investment. You decide if the bottle is worth it. I love mine and intend on using it for as long as it lasts.

I love these new water bottles with the vacuum technology in them. It really makes drinking water enjoyable knowing that every time you crack the cap its just a cold flow of H2O. I have left this bottle with ice and water in it for days and the ice doesn't melt at all, it's incredible. I love the size of this one too, at 40 oz. it holds enough liquid to keep you hydrated for a few hours. I would recommend this product to everyone, because everyone needs to drink water to live and this makes it even better.

Keeps the water cold all day you never have to worry even after hours of hiking the water is still ice cold and so refreshing!

the best water bottle you can get, keeps water cold or hot for a very long time

I now own five Hydro Flasks and i can honestly say that i will keep buying them, they are absolutely amazing for both hot and cold drinks. The 40oz bottle is by far my favorite, yes its heavy and big but for everyday life its great to fill with ice water or tea depending on the day and have it stay hot or cold all day long is such a large quantity.

Being 25 days in a trip finally I have to said yes and gave up my favorite water bottle, everybody love it so I had no chance and I bought another one. I feel so nice about my Hydroflask when people didn't stop talking about how cold the water can be even within 7 hours out of the fridge.

Hydroflasks are great! Bottles are insanely durable, and can keep you drinks cold for days, or hot for hours. I love the 40oz, fill it up with tea and use it as a thermos for those cold days out touring.

Has this bottle for over a year I've dropped it a couple of times and put a few dents in it but it still hold up great. Excellent bottle to take on all kinds of adventures.

This water bottle looks better with dents. Drop it off your bike, pack, or out of your hands... it's fine. It holds temperature for hours. If you are putting hot liquids in it the outside of the bottle will not be hot. The lid never leaks. Not the lightest bottle but who cares. This thing is burly. Awesome colors. Everyone loves Hydro Flask.

As a teacher all of my colleagues are obsessed with these things. The ability to keep things cool for so long is important to us, as we don't have the time or ability to be constantly be adding ice to our water throughout the day.

I recommend these to anyone that wants to keep their cold drinks cold, or hot drinks hot... they perform flawlessly. And they even look dignified after being dropped and dented up!

unfortunatley the lid has broken in two places tho

I've joined the bandwagon of Hydro Flask. I'm a River Guide in Utah and this bottle becomes an extension of my body throughout summertime. I fill it with ice and by the end of the day, they're still ice in it, even through the desert heat.
On multi-day trips, the ice melts pretty fast. This isn't from the heat of the desert, but from additional water I add to it constantly through the day.
I've duct taped webbing on the bottle for a shoulder strap on this bottle. This makes it so I have this bottle on me most of the day, most of the summer. I'm probably too attached to it..
My only warning for anyone looking at these: these bottles are not indestructible! They are made of metal, but that does not mean you can abuse them. If you dent them bad enough, the walls of the bottle will touch and it will lose its insulation, and all you'll have is a heavy metal Nalgene.
