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

Love this bottle I was able to hook it right on my backpack and head out for a 3 hour hike. It holds 40 oz of water and the mouth is large enough to use the ice dispenser on the fridge to fill it. After hiking my bottle still had all the ice and it seals great!

I have had this flask mug for a couple weeks now and I love it. It is very large and holds around 40 ounces of liquid. My hubby has been using it for work since he works outside all day he puts ice water in it and it will keep the ice all day. You would think after and hour or so the ice would be melted but not in this it keeps it cold all day long. We haven't tried it with hot liquids yet but it is amazing at keeping ice. I love the lid, it goes on tight and has a little handle so I can carry it easily. We have even dropped it and it is such a thick metal casing that is didn't hurt it at all and nothing spilled out. This would be great for hunting, fishing, days at the park or anything else. Truly a great cup.

Like many other people toady, I'm trying to achieve the healthiest version of myself that I can. By doing this, drinking more water is a must, but unfortunately most bottles are unable to keep your drink cold enough throughout the day. Hydro Flask is NOTHING like the rest, but actually the BEST! I have gotten my drink ready for the day in the early morning and it's still cold even as I'm drinking it hours later! The wide mouth makes it easy to add liquids and ice if desired. I do recommend getting a wide mouth straw and hydro flip, to give you more drinking options, but this is by far the best insulated bottle that I have ever owned!

Hydro Flask makes a great product once again. The bottle allows me to keep ice from melting during a full workday which allows me to have to have ice water all day long. It also has worked great for me while out boating for extended periods and still maintaining the ice cold water.

This came righ at time i was making switch from plastic waterbottles so was glad to get this 40oz size since its easier than using smaller size one and refilling frequently . The bottle is well built and the handle is so convenient definitely love it for daily use

I love this bottle, is perfect for my daily use at work and home. Maintain everything cold or hot for hours. My water is always cold and my coffee is always hot. You can use it for any drinks cold or hot. Is very resistant and durable and I like is BPA free.

Not only does this keep my water cold for more than 24 hours, but the ice is still intact. If I preheat the bottle with hot water before filling it, my coffee will be steaming hot 12 hours later. I love the 40 oz size. It holds enough beverage for an entire day, and the wide mouth makes filling easy. The stainless steel does not retain flavors from previous beverages. The colors are fun. I don't know what I did without this!

I love this Hydro Flask. I sometimes forget to drink enough water throughout the day, so knowing I have at least 40oz. if I fill it just once is awesome. I did a test with ice water and let it sit overnight. In the morning it was still ice cold! I need to test it with my morning coffee as well, but I'm pretty much 100% positive it will stay nice and hot. I've also received many compliments on how neat the design is. Always a great thing to reduce your carbon footprint!

This bottle keeps drinks cold for hours! I'm a teacher in a very hot climate. I fill my bottle at home with ice and water before work. Half way through the day I add more water and there's still ice inside. I bring this bottle out for our track time (5 laps) and for 30 minute recess. By the end of the day I have a small amount of ice and cold water.

I've been pretty skeptical about products that have this promise for long term cooling or long term heating. I must say, though, that this item doesn't disappoint. I really love it. I'm primarily invested in it to keep water cold, and indeed, my water stays really cold for hours--I'd say close to a day, and even though the inside is metal and I've been concerned about an aftertaste, there is none. The notes I have is that because it keeps on cooling the liquid, it also takes longer for the product to cool -- in fact, you don't actually know it's cold because the exterior stays at room temperature. Therefore, while other water bottles will take an hour or two to get very cold in a refrigerator, this appears to take several more. Still, once it's cold, you're going to have a refreshing for a long time thereafter, making this a great product. Also, a 40 oz bottle is big and heavy, so this is not for a side pocket of a backpack or whatever else. The cap also fully removes from the product, so it could get lost.

This water bottle is a perfection. Very well insulated. It keeps my water cold for a good 24 hours. I have no issues of water leaking or smelling bad. The cap stays secure & is very easy to carry on. Definitely a must-have for travel.

This is a "thermos" on steroids. Very nice design. Keeps liquids either cold or hot for a long time. Is light weight but very sturdy. Very high quality. Not your Grandmas thermos! Great for football season!

Love the wide mouth! It makes pouring my drink of choicea lot easier. It holds forty ounces, which is more than normal and plenty enough for what I need . My drink was still cold and with ice even after sitting in a hot car when it was 95 degreees. I plan to purchase another.

I love that this is a large flask it makes it easy for me to remember to drink my water. The wide mouth also makes it super easy to clean the inside of the flask. the handle makes it easy to take on a trip for easy carrying and it keeps my water super cold for hours on end even in this Georgia heat!

This by far has got to be one of the best Brands if not the best brand in regards to this type of growler. I fill this up in the morning with some ice cold water and use it throughout the day. It keeps things ice cold for at least 10 hours with ease. I highly recommend this product.

Excellent durable, sturdy water bottle. I take one to the gym with me every day, so it gets knocked around quite a bit. I love that it's insulated- I can put cold water in it in the morning, and it keeps it cold all day!! Even when I leave it in the car on a super hot day. It also doesn't sweat! I like the top handle- makes it easy to carry. Would love a sport top for it!

I got this water bottle free to keep in exchange for an honest review. This is my new favorite bottle, it stays cold all day & holds lots of ice. It also has a wide mouth & a holder do it fan be snapped on to a lanyard or bookbag

I recently bought this product as I am a college student and many of my friends own this water bottle and recommended it to me. Its actually really nice and doesn't appear huge for something that holds 40 oz of water. I bought the flamingo color and it is extremely bright neon pink (almost like a highlighter but still somehow brigher) - so just fair warning i think it is much brighter and lighter than in the picture, but I still think it is cute as I didn't want the blue or teal but still wanted a color.

I have been super happy with this Hydro Flask 40 oz Wide Mouth - Pacific bottle, and have found myself drinking more water than before. This product is super durable, keeps everything cold or hot long time, and I really love the handle on this too. It's easy to carry around and it's not made of a flimsy material, I can really take it almost anywhere. I really like this insulated water bottle. Awesome insulated water bottle. I enjoy using this one. Perfect for travel and camping.

I got this as a freebie for writing an honest review...............................( a long one I guess lol ) this flask holds 40 ounces of water................ It oeeps cold for a long time. And it also cleans very easy. I would recomend this flask to anyone needing to keep a cold drink for camping running long walks or work.

I absolutely love the Hydro 40 oz. flask. It has a great design and holds enough fluid for a day hiking trip. It keeps the liquid temperature hot for hot liquids and cold for cold liquids. The design is simple and clean.

I very much enjoyed the hydroflask water bottle. It was of high quality and the paint stayed on very very well. It keeps things cold for an acceptable amount of time.Everyday use. I love that it keeps my water cold in the AZ heat. I also like that I can just throw it in a bag and go with out it leaking.The color is very vibrant and smooth, I quite like the light blue color I chose! This bottle is great over all, and you can rely on it not breaking!

I am so happy to have this flask, I mostly drink water and sometimes I add powders to it before go to the gym. I love the Hydro Flask 40 oz wide mouth flask because it keeps my water at a good temperature. It keeps my drink cold all day. And since it is made of steel, it is easy to clean. I love the wide mouth cause I drink fast and it make it easy to put my powders in. This is just so much better than any other bottle that I own and it holding 5 glasses of water, I just have to fill it once in the morning then once at the gym and I get most of my water for the day. Now it is a big flask, it is not going to fit in your car holder or in the side of most book bags. I put it in the bag itself. It has a handle and I carry it around with me since I am constantly drinking. The flask is not heavy itself. The only real weight is the weight of the liquid. This is going to last me a very long. time. I plan on also using it for soup and coffee during trips. I am very happy with it.

I got this for my husbands work. I works long hours in the heat. This keeps cold drinks cold for 24 hours and hot drinks hot for 12 hours. It is big enough to wash good. And big enough t quench some thirst.

I had the opportunity to try out this amazing water bottle and it's perfect for me because I constantly take water bottles with me to work and it is so useful for both hot and cold things. It really does keep things cold and keep things hot when you need them to be. Its got a great wide mouth for drinking and its really heavy duty quality. It would be really hard to break! I love the color and it really is an exceptional product! Very happy with this!
