    Rated 5 out of 5 by from Excellent! Worth price! Love this! My son uses it perfectly! Great for on the go, anywhere. Had bought some “sale” hydroflasks thinking I’d found a steal, but were from 3rd party/China :( the straws and lids from real hydroflask are excellent and cannot be chewed through like some people have mentioned in other reviews (& as my son did with the knockoffs). So- bottom line: worth the price! Excellent product!

    Rated 5 out of 5 by from Adorable This was labeled as a Kids Wide Mouth, but I'm almost a senior citizen. I have the 40 oz. wide mouth and a few 20 oz. coffee bottles. The 40 oz. is a bit heavy when it is filled. The 12 oz. Kids Wide Mouth is much lighter and easier to carry, when it is filled. It comes with a blue boot. I purchased a pink boot only because I wanted to use the blue boot for a red 20 oz. coffee bottle.

    Rated 5 out of 5 by from Hydro flask fam Every person in my family has 2, one for on the go and one in our rooms for at home and night time hydration. That includes my 1 yr old and he absolutely loves his! Just wish we could get the beautifully colored tops and boots for our bigger flasks too! Always cold and delicious.

    Rated 5 out of 5 by from Perfect size I purchased three of these for my littles. They LOVE them. We use them daily and it’s encouraged them to drink more water. They each chose their favorite color which was fun for them. That they come with the boot is terrific - less banging around. Would buy this over and over.

    Rated 5 out of 5 by from My sons water stays super cold! I bought this for my 4 year old son who will only drink water ice cold. Our older son has baseball tournaments out in the heat of Southern California so we put ice in my younger sons hydroflask and it stays ice cold all day!

    Rated 5 out of 5 by from Cooper approved I purchased this for my grandson Cooper who is turning one soon. His mother said that if he doesn’t have his HydroFlask with him in the car, he cries. The whole family has HydroFlasks but this is a perfect size for him. Love the colors too
    Date published: 2019-07-01
    Rated 5 out of 5 by from Perfect for colored accessories I have no kids and I did not purchase my own kids flask for the other children that are in my life, but I have some bigger flasks that if I wanted matching accessories like boots or straw lids, the colors are either retired or just not produced to buy on their own. I LOVE mixing and matching colors on my flasks, so this is a very easy (kinda) way to do it! I bought a flamingo color from another retailer literally for the straw lid. However now I have a fun boot for my 24oz flasks and a 12oz flask that can be a coffee cup. I GREATLY appreciate how flexible Hydro Flask products are so that this purchase wasn't *entirely* crazy (still a little nutty on my part, no lie). I can use this one purchase across 3 products at once.

    Rated 5 out of 5 by from Well designed Got 2 of these for our kids and I’m very impressed. The lid is very easy to unscrew and put back on, they really got the tolerances right. Also, I like the multi function of the anti-slip jacket on the bottom. The extra straw was a nice touch and they are also well made. Just a really solid drinking container. Well done guys.

    Rated 5 out of 5 by from The best water bottle on the market! I'm obsessed with this water bottle!! The colors are so vibrant! I personally ordered the lemon colored bottle... I love it! I've seen several reviews regarding the lid. People have said that it leaks but when closed, but mine doesn't at all! It is amazing quality and the bottle doesn't leak. It is totally worth the money! They sell the tops for $10 on the site, and the silicone bottom for $10 too! The value of this bottle is amazing... and it's not too small. I'm not the type of person that normally writes reviews... but I'm so pleased! I find this water bottle to be adorable! It's perfect! Thanks Hydro Flask for creating this amazing bottle!

    Rated 5 out of 5 by from Our baby loves this!!!! We bought our 16 month old son a Hydro Flask a few months ago because he loves to drink from straws and all kids cups with straws are awful! He LOVES it!!!!! Water stays cold, easy to open, he can hold it by himself, fits in the diaper bag,and it's not going to slip everywhere because of the bottom. It's not $4 but worth every penny!

  • Are these kids straw bottles leak proof or resistant?  Do the bottles contain lead or have a lead dot at the bottom? Does the paint contain lead or expose lead if chipped?  Can they be washed in the dishwasher? If not what is the risk if they are

    Asked by: KElseyB
    None of our caps are advertised as leak proof. The flasks do not contain lead. We do not recommend putting the flasks in the dishwasher, it could cause them to lose their insulation abilities. If they are put in the dishwasher, it will void the warranty.

    Does the lid come with the straws to cut or are they already cut to size? Can you purchase just the straws?

    The straws are one size so they need to be cut to fit the flask you have. The straws are not available to purchase, however, we can send a replacement cap that comes with two straws.
