I had purchased one of the limited editions a few years back for the Parks for All partnership I got the Hawaiian Volcanoes 32 oz flask and was super satisfied. I began looking around for a new canteen for my new job that will be outdoors in the Texas elements. I decided to come back for another Hydro Flask for work and got one of the larger canteens the 64 oz in black with the flex straw. I have already been using it for a few months and I am satisfied again with Hydro Flask. For a 64oz it's very light weight, i personally noticed it kept my iced water colder a little longer than 24 hours, and durable I have accidentally dropped it, banged it and scuffed it and its still holding up. I also enjoy the fact the products are very easy to dissemble and clean. BTW I totally recommend at max a weekly cleaning and not just for Hydro Flask but for any other product to prevent build up of gunk and mildew. But overall the canteen is a great buy, and now that summer is around the corner I am excited to have a container filled with water for my work day. Hydrate Hydrate HYDRATE!!!!! lol.

5 Joy S.
[ As a working mom who frequents the gym, this is the perfect size. Helps me regulate my water intake and ensure I ’ m getting enough throughout the day. Typically only needs to be filled up twice a day. Love it!

5 Ana R.
[ It ’s great! I just wished they ’ ve offer engraving as well. But no complaints here!

5 Tricia P.
[ This is great for long work outs. It stays full for hot yoga and the gym, unless its summer. Then the flask is good for just for hot yoga.

[ The wide month makes it easier to insert ice cubes then my old HydoFlask. Also I like the not having to tip the bottle up to drink from it. Still fits in car cup holder and keeps drinks cold longer the any other I tried

5 Steve P.
[ Hydro flask products are always the best. This one fits in the cup holder and is comfortable to carry.

5 Ellen W.
[ I loved my custom Hydroflasks and the Mothers that I got it for loved it!!! I have learned that the images should have been drawn in black Sharpie as the yellow designs did not come through so girls and Moms were essentially bald!!! One Hydroflask came with two designs imprinted on it- don ’ t think that was my mistake but who knows??? Other than that, the Hydroflasks were loved by everyone because of the custom designs from daughters!!!

5 Israel S.
[ This water bottle is by far the best in the game. Keeps water cold and refreshing

5 Dena F.
[ I love the 32 oz. wide mouth Hydro Flask! I drink a lot of water, so it saves me trips to the kitchen, and it keeps my water cold, without condensating, due to the vacuum seal. It's stainless steel, so it's going to last a long time and replaces single use plastics from individual water bottles. The wide mouth is big enough to put regular ice cubes in it. It comes in lots of pretty colors, and it's leakproof! I highly recommend Hydro Flask!

5 Mavis K.
[ Love Hydro Flask for work it keeps my water cold all day long!

5 Debra M.
[ Greatest bottle ever. It will make you want to drink more water. Keeps water cool all day.

5 Jordan
I absolutely love this bottle. I was hesitant to order it because I have small hands and I thought it might be uncomfortable to hold. I was wrong and it ’s perfect! The flip straw is great and there is no resistance when drinking. It ’s perfect!

Super happy with this bottle now with about 30 miles on it. Definite improvement over my old, non- insulated bottle. Pockets are large enough for several gels and/or an iPhone 14 in it's case. Hand strap is very comfortable with no signs it 'll give me blisters.

Frequently Asked Questions For Large Flasks

Large flasks are designed to hold a significant amount of liquid, making them ideal for long outings, whether you're hiking, camping, or engaging in sports. They reduce the need for frequent refills, allowing you to stay hydrated without interruption.

Large flasks are typically made from stainless steel, plastic, or glass, each offering unique benefits. Stainless steel is durable and often insulated, providing excellent temperature retention. Plastic options are lightweight and often more affordable, while glass flasks are eco-friendly and do not retain flavors, though they can be heavier and more fragile.

Yes, many large flasks are designed to accommodate both hot and cold beverages. Insulated models can keep drinks hot for several hours or cold for an entire day, making them versatile for various activities. It's important to check the specifications of the flask to ensure it meets your needs for temperature retention.

When selecting a large flask, consider features such as insulation type, lid design, and ease of cleaning. Insulation can significantly affect temperature retention, while a wide mouth opening can make filling and cleaning easier. Additionally, look for flasks with leak-proof lids to prevent spills during transport.

Absolutely! While large flasks are primarily designed for hydration, they can also be used for carrying soups, smoothies, or other liquids during outdoor activities. Their versatility makes them useful for picnics, road trips, or even as a container for hot beverages during winter sports.
