  • 18 oz Wide Mouth is rated 4.1 out of 5 by 61.
    Rated 5 out of 5 by from Best bottle ever I bought this for my 9 year old son because he kept taking mine. It’s worth every penny.

    Rated 5 out of 5 by 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: 2019-03-19
    Rated 5 out of 5 by 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!

    Rated 5 out of 5 by 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.

    Rated 5 out of 5 by 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.

    Rated 5 out of 5 by 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!

    Rated 5 out of 5 by from Amazing I really love my Hydro Flask! Great quality for an ok price. Actually considering buying another!
    Date published: 2019-03-08
    Rated 5 out of 5 by 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!!

    Rated 5 out of 5 by 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.

    Rated 5 out of 5 by from Awesome bottle Bought it on sale for $24 n totally worth that. Nice powder coating on it. Feels durable. Time will tell
    Date published: 2019-02-14
    Rated 5 out of 5 by 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: 2019-02-12
    Rated 5 out of 5 by 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 18oz

    Rated 5 out of 5 by from One of many I have given as a gift I own a ridiculous number of HF products, and give them as gifts regularly. First one is on me. Thanks for the closeout prices on discontinued colors. ♡
    Date published: 2019-02-09
    Rated 5 out of 5 by from Nice and cold!! I bought this for myself after I asked for it in a family gift exchange but never received any gift so I bought it for myself and I am happy I did!! I am impressed that my water stays cold for over 48hours. It’s a perfect size I like that I can change the cap. The only thing I am disappointed about is the color. When I ordered it I asked for Mango but it is more yellow in person. That is my only complaint lol
    Date published: 2019-02-07
    Rated 5 out of 5 by from Great features but could be improved I bought this flask which came with the standard twist off with handle. I also purchased the flip top, which made it easy to drink while driving. The perfect scenario would be to also have the handle on the flip top lid. That would make it the perfect flask!
    Date published: 2019-02-06
    Rated 5 out of 5 by from Love it We liked the hydro flask so much we have them in different sizes
    Date published: 2019-02-05
    Rated 5 out of 5 by from Perfect Size I love this hydro - it's just a bit smaller so it's great for soups or hot drinks, I use it for smoothies, etc., but could also work well as a water bottle if you dont' want to lug around a ton of water! I'm a big water drinker, so I go for the big guy for H20.

    Rated 5 out of 5 by from Best bottle Best water bottle out there! My whole family loves them too! We actually have a kitchen drawer that is our hydro flask drawer! Dependable, consistent and lots of fun colors!

  • What are the height dimensions for the 18 oz wide and standard mouth bottles?

    Someone 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?

    Asked by: Moonpie
    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.

    The 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?

    Asked by: Cms1221
    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.

    Are they dish washer safe? Can the 18oz wide fit in a car cup holder?

    Asked by: Maddie11
    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.
