Customer Reviews Hydro Flask 40 oz Wide Mouth with Flex Cap 2.0

I bought the 40oz because we are going camping soon. To test it out I left it in the baking sun 100 degrees and sitting on our truck hood for six hours. It was freezing cold and still had ice after the six hours were up. I have filled it with ice and water and by the next day it still had ice and was freezing cold. The no condensation is a plus too. Well worth the money.

I one two months ago, and I'm so glad I did! It keeps my water cold all day!

It holds ALL my liquids nicely. It's just a beautiful piece of metal. Keeps the cold cold and the hot hot.

I bought my 40oz a little over a year ago and could not be happier with it. I have tried several different brands of water bottle over the years and this is by far the best I've ever had. It'll keep ice in a 100+ car for hours on end and even when the ice has all melted the liquid inside will stay cold for long after. I have recently bought a straw lid for it and they are the perfect combo. Couldn't ask for much more than this.

I bought this for my boyfriend because he's a chef in a hot kitchen in Nashville and the plastic bottle with a straw that he had would sweat all over his car and get his bag wet when carried from the car to workplace a few blocks away. Now he has his 40 oz Hydroflask and has even bragged a couple times to me about how the ice in it is from yesterday or whenever. It's like he's a scientist with a new invention. Trust me, for him to brag is huge. He's already dropped it to christen it with its first ding. Now I can send him off to work over an hour away and know he has his refreshing cold water in the summer or his huge flask of piping hot coffee in the freezing cold winter (cause I got him the coffee lid too). His only complaint is that it won't fit in his car cup holder. I'm sure that is probably a logistical issue for the capacity of the bottle. His old plastic one didn't fit either, so oh well. Great product y'all!

My mom turned me on to HYDRO FLASK! Love it!!!!!!!

The dual clasps top is great. Easy to handle and looks tough

Such a great product always keeps your drinks cold or hot for hours

I own most of the Hydro flask products and love them

I cannot recommend this water bottle enough. It is by far the best bottle I have ever owned. It really does keep water cold all day. I fill the bottle with ice and water in the morning, and by the time I get home almost 15 hours later, it still has ice in it. Some days, that's after it has sat in my hot car for several hours, in direct sunlight, and it is still cold. I haven't dropped my bottle yet so I can't say how well it holds up to that, but it looks and feels very well made. I got the kiwi color, which is beautiful and the powder coating is done very well. I have friends who have this bottle with the old cap and I can definitely say the new cap is a big improvement. The material is better and the handle seems very durable. This bottle is a little pricier than other similar bottles, but I think it is completely worth it. I see myself having this bottle for a long time, and I will definitely be buying more. I will never go back to a plastic water bottle again!

I needed a water bottle to keep water cold after several tries with other less expensive bottles I broke down and paid for the 40oz hydro flask. let me tell you it is worth every single penny. I was very doubtful so I immediately starting testing the bottle I filled it with ice sat it on my desk at work for 24 hours ice still there. then I filled it with water with same ice left for another 24 hours and OMG the ice was still there I LOVE THIS BOTTLE. So if the price is the only thing holding you back fear not this is very much worth it.

Keeps my water cool for hours, and the wide mouth makes it so much easier to clean.

I use my 40oz bottle everyday for work and it keeps my water ice cold all day long! Even in my hot car, talking 100+ in Las Vegas! My HydroFlask stays ice cold even when the outside of the bottle is hot! Best product ever! My coworkers went and bought themselves one because I am always raving about mine! :)

I have one already. So one for water, one for coffee.

Take it to work with me in the patrol car, keeps everything cold

I bought my 40oz. Bottle three days ago and love it already! I originally bought it for a camping trip in a few weeks and thought I would test drive it on a trip to Disneyland during a heat wave. It proved to be a gem! The 40oz. size was so convenient! I didn't have to keep refilling it over and over again and it was compact enough to fit in my smaller-than-usual cross body hand bag. I can't get over how long and how cold it kept my water! With a typical water bottle your liquid becomes warm and unrefreshing, however my Hydro Flask kept my water the perfect fresh temperature all day! The warranty on this bottle makes for such a smart buy that I may need to invest in a 64oz. bottle as well.

If you are contiplating buying a HydroFlask, do yourself a favor and buy one. My wife and I first heard about them while visiting friends in Hawaii. They swore they kept their water icy all day in The tropical humidity. I work in the field so that appealed to me. Now, Hydroflask is the only container I use for water! I cannleave my water bottle in the car and return to ice cold water. The water stays cold for up to 24 hours, and best of all, no container sweat!

I love all of my hydroflask items! Durable and great for hiking and working out

It's an amazing piece of gear that keeps things cold. I had ice water in there for two and a half days and it was still cold! Awesome love it

I bought my 32 oz bottle about a month ago and have used it every day since. It is amazing at keeping water cold all day even when left in the hot car for 6 hours on an 85 degree day. Seriously! Best investment in a bottle! Just buy one (or two), you won't regret it! =)

Durable, excellent quality. Easy to grip. Keeps water cold

Sturdy, reliable and every day use achievable without wear and tear.

I love these bottles and I think my friends will as well.

I love the size! It can be quite heavy if it is full while backpacking through the woods.. it's best to fill it when you reach a water source with an appropriate water filtering system.

Very happy with the product. Has held up through falls and dents that would compromise most regular bottles and it still works as well as when first purchased. Well worth the buy.
