Perfect size

Love it!! Hydroflasks never fail me, this is my 4th and I don’t feel bad about it because they’re all different sizes. I love this one because it fits in most of my purses and it’s the cutest color.

Okay

[This review was collected as part of a promotion.] I have had many hydroflask but for some reason this leaks. I even changed the cap but it still leaks occasionally

Cool change

[This review was collected as part of a promotion.] Love that I changed to the straw slipper, drinking more water, but I stubbed the quality of my Hydro flask to keep it cool

I’d buy again but it isn’t my fave

[This review was collected as part of a promotion.] Got these for my kids. I purchased the straw lids separately. They leak and don’t seem very durable. My son barely dropped his and it has a huge ding in it. Never happened with our contigos or yetis. I bought these as a replacement due to the concern for lead in contigos and other brands. I wish I could say I love these but they are just ok. Not terrible but nothing like yeti or contigo on the leak and sturdiness front.

Yippee! Just what I’ve been looking for

[This review was collected as part of a promotion.] Thanks for this excellent product it’s just what I need! I aim to drink 10 glasses of water daily and so many water bottles are way more than 2 cups. This 18 ounce water bottle makes it easier for me to keep track of how much water I’m drinking. I bought two 18 ounce flasks in different colors and alternate the liquid that I put in them: sometimes tea, sometimes electrolytes, mostly water. I hope you keep making this 18 oz size! It’s Also leakproof. The only improvement I would encourage is that it come with a standard stainless steel top. Thanks again for a top-notch product.
