Q & A
- 18 oz Wide Mouth is rated out of 5 by 69.Rated 5 out of 5 by anae303 from Great size for a commuter. I purchased this because I wanted an everyday bottle I could carry with my to and from work. The size fits my needs because it is small enough to comfortably pack in a backpack or tote bag, but still carries a good amount of water so I can quench my thirst throughout the morning. I do need to refill it about halfway through the day, but then that will get me through the rest of the workday. It truly does keep ice water cold for a whole day. I definitely prefer the wide mouth opening so I can easily put in lots of ice cubes, and I also find it more convenient to clean. The cap has been leak-proof thus far, and the small handle on the cap makes the bottle comfortable to carry. I purchased the silicone boot accessory, which makes setting it down on counters and tables feel better. And lastly, the Lilac color I got brings me joy. :)Date published: 2019-04-05Rated 5 out of 5 by maddie546 from Amazing I swear by this water bottle. I never drank water until I got this. It's cute and it keeps my water cold, which is usually my problem. When I got this water bottle (about 2 months ago) I wasn't expecting it to keep my water cold for a long time but I can 100% say that it does what it says it will do. They have great colors of these water bottles and a size for anyone. I chose the 18 oz. one and I'm going to buy a bigger one because of how great this has been. It's what i buy people for their birthday presents now.Date published: 2019-04-03Rated 5 out of 5 by Hannah831 from Easy to Use! I bought it a month ago and I'm so happy I did. It's better than the cheap walmart water bottle I use to have.Date published: 2019-04-01Rated 5 out of 5 by Samantha_alizabeth from Great astetic ”I bought this a month ago and I'm so happy I did...” it's super cute and I put red bubble stickers in it and its just greatDate published: 2019-03-30Rated 5 out of 5 by Leysha from Hydration I’ve always struggled to drink water, mostly because I’m weird and I like when my water is extremely cold otherwise I won’t drink it. After purchasing this, I’m feeling so much better drinking water’s never been so fun And addictive! Thank you!Date published: 2019-03-24Rated 5 out of 5 by Pinta01 from Best bottle ever I bought this for my 9 year old son because he kept taking mine. It’s worth every penny.Date published: 2019-03-23Rated 5 out of 5 by EmilyDeVos from Keeps smoothies cold I ran out of the house this morning and threw my smoothie in here. I'm just opening it 3 hours later, and it is still as cold as when I made it. So great! I am in awe.Date published: 2019-03-22Rated 5 out of 5 by mmoon19 from Favorite Water Bottle I bough this back in September of last year and I love it! Use it everyday and it motivates me to drink more water each day.Date published: 2019-03-19Rated 5 out of 5 by liliana from Amazing Bottle I loved everything about it! I bought it for school so that I could have cold water all day. It don’t disappoint! It is the perfect size and wasn’t too expensive. Definitely recommend!Date published: 2019-03-17Rated 5 out of 5 by Ary123 from Adorable! This hydro is so cute, I bought it about a month ago not expecting if the size was going to be good but it turned out to be great! I have another hydro that is 32 oz which isn't always the easiest to carry so this one made for perfect size. It also fit my car cupholders which is a major plus. The light baby shade of blue is also very adorable and they should come out with more light colors. I get many compliments on my hydro because of its color & size.Date published: 2019-03-14Rated 5 out of 5 by ellez from Love my Hydro! I bought this specifically for the wide mouth, since my Swell had such a tiny mouth! Highly recommend if you prefer wider mouths.Date published: 2019-03-13Rated 5 out of 5 by Sandy94 from LOVE IT I find myself drinking more water out of my hydro! I love it!Date published: 2019-03-12Rated 5 out of 5 by Océane from Nice bottle overall I bought my hydroflask one week ago. This is definitely just the great size for me (I ordered a 18 oz). I really like the rugged texture on the bottle as well as the handle over the cap. The bottle is also able to keep my water cold for about 18 to 20 hours. Overall a great buy!Date published: 2019-03-10Rated 5 out of 5 by CC28 from Amazing I really love my Hydro Flask! Great quality for an ok price. Actually considering buying another!Date published: 2019-03-08Rated 5 out of 5 by Juliaaaaaaa from Love it! Amazing! At first I did have some doubts about the size and I thought it would be too small, but I was wrong. its the perfect size for me. It’s not too big nor too small. But if you’re a big water drinker I recommend a bigger size. Overall I love love love it!!Date published: 2019-03-05Rated 5 out of 5 by bsacc from Literally perfect I bought this water bottle about a month ago and I'm so glad that I did! I never thought I would be so excited about a water bottle, but here we are.. I absolutely love that it keeps my water nice and cold ALL DAY. I've tested it out and put juice in it once, and another time I put in coffee, and it does not keep the flavor of your old beverage after you rinse it out which is nice. It's super easy to clean too- I use a little vinegar to swish around the inside and bam brand new once again.Date published: 2019-02-15Rated 5 out of 5 by Cashout4 from Awesome bottle Bought it on sale for $24 n totally worth that. Nice powder coating on it. Feels durable. Time will tellDate published: 2019-02-14Rated 5 out of 5 by Harfk48 from Lives up to the hype In the past I have had a problem of not drinking enough water, so I got two 18-oz.—one for home/car, and one for work. Amazing how long it stays icy cold. I have not had any leaking from the straw attachment and love how it works!Date published: 2019-02-12Rated 5 out of 5 by Loulouli15 from Forever love my hydro flask I LOVE MY HYDROFLASK!!! This is my second one because I’m an idiot. It’s definitely worth the price. It was a little smaller than I anticipated but I guess that’s my fault because I got an 18ozDate published: 2019-02-10Rated 5 out of 5 by Bk4907 from She loves it! Bought it for my wife and she loves everything about it! Great product!!!Date published: 2019-02-09
What are the height dimensions for the 18 oz wide and standard mouth bottles?
Product dimensions can be found on our FAQ page. You can see them here: http://www.hydroflask.com/frequently-asked-questions/Date published: 2019-01-03Someone asked about the difference of coffee flask vs regular hydroflask and customer service answered nothing but the cap. But the description says the coffee flask keeps hot beverages hot for 6 hrs and hydroflask keeps it hot for 12 hrs, so which is it?
The flasks are the same. The difference is in the cap. The hydration flask has a better insulating cap in the flex cap, which is what gives the time difference.Date published: 2018-09-09Will these fit in a standard drink holder in a vehicle?
Product dimensions can be found on our FAQ page. You can see them here: http://www.hydroflask.com/frequently-asked-questions/Date published: 2018-12-13Hello , where is Hydro Flask Manufactured ?
Our flasks are manufactured in China. Our caps are made in China and the USA.Date published: 2018-12-13can I Geta replacement rubber seal for my flip back lid, 18 oz Hydro flask?
We'd be happy to replace your cap for you under our Lifetime Warranty. You can fill out a warranty claim here: (http://www.hydroflask.com/warranty/)Date published: 2018-12-13The straws fit into the 32oz but not the 18oz tumbler. Why do you sell a straw lid and not a straw that works in this cup?
The straw cap would fit any wide mouth flask. Including the wide mouth 18 oz flask. The straws just have to be cut down to size and there is a cut guide on the back of the package.Date published: 2018-04-28Are they dish washer safe? Can the 18oz wide fit in a car cup holder?
We do not suggest putting your flask through the dish washer. For cleaning, we recommend hand washing with a bottle brush and mild dish soap.Date published: 2017-12-22What are the size specs?
