Why change a good thing? The 18oz insulated water bottle is one of the original Hydro Flasks produced, and continues to be a popular water bottle today. The smaller mouth size means great pouring control and less spills, and the smaller volume makes it easy for stowing in your bag, purse or elsewhere.
The 18oz insulated water bottle is designed to keep cold liquids chilled for up to 24 hours and hot liquids hot for up to 12. The double wall 18/8 stainless steel means no condensation buildup on the outside of the bottle and the non-porous, rounded corners on the inner layer help to eliminate bacteria buildup and odors.
Hydro Flask is proud that the all our products are BPA-free, 100% recyclable and are backed by a lifetime warranty. Look for the H-guy and Hydro Flask logo to ensure you’re getting the market’s premium insulating beverage bottle.

Great for keeping ice water cold. Small size makes it easy to pack.

I have had quite a few stainless steel bottles, but ultra cheap to Kleen Kanteens, and have had issues with most. So when I wanted a new bottle to take to work, I searched my local stores and reviews online. It came down to an insulated Kleen Kanteen or a Hydroflask. Even though the Amazon prices for Kleen Kanteens were less than for Hydroflasks, I decided the excellent reviews of the Hydroflask were worth considering. I ordered the Hydroflask and am so happy with my choice. The Hydroflask looks and feels great, isn't quite as trendy as Kleen Kanteen (I like that), and works extremely well for keeping cold water on hand to drink. This thing keeps water cold for hours (all day, as far as I can tell), and is easy to drink from. Its well made, and easy to wash too. Highly recommended.

This is a must buy for anyone who has a nalgiene or any type of popular water bottle. This thing keeps cold drinks cold and hot drinks hot. Just buy it

This works. It really works so well that you'll have ice 24 hours later still in the container. Doesn't sweat and is not cold (or hot) to the touch. Pricey but worth the money if your looking for a well made product.

THIS IS AS STEEL AS IT GETS. This keeps my water cold cold and I don't even have to put ice in it to keep it cold. It is a decent size. The only thing I wish it had was sort of an easier to drink for more of a convenient pleasure and so I don't have to taste metal. You have to open the whole lid to drink. Other than that, this is a great purchase.

Just what I ordered. Purchased several for family members. I also have a second bottle as a backup. I have dropped it and it was not damaged. Everyone that I have given them too love it.

Gave this to my son for Xmas. He says it is the best sports bottle he has ever had. The insulation keeps his drink cold from gym to school.

This water bottle is very well made and keeps liquids cold for at least a day or two. I've been extremely pleased with it, and it goes everywhere with me.

I have the Hydro Flask with Hydro Flip and it is the best insulated container I have ever had! Keeps coffee hot or cold beverage cold all day--No kidding!! It also cleans easily and does not seem to keep that subltle coffee taste when using it for other beverages. I plan on getting the food container next! Also will be getting some for Christmas presents!

I purchased 2 units thru an offer made available on GMA in the summer. I tell you it is one of the best purchases I have made. I does keep the beverage cold for a long time. I place ice and water in the morning around 8am and then fill it with just water (because it still has the ice) again 2 more times before 5pm. Just amazing to be able to drink colder water at work. Love it! I plan on buying a few for X-mas gifts and another for myself.

I have 4 Hydro Flasks currently (18 narrow, 18 wide, 40 wide and 64 growler) and always have one with me. I am a director for a rec lacrosse league and spend most weekends baking in the Georgia sun on the field. All day every day I get back an ice cold beverage... Really a great product!

You make my favorite water bottles. I use them every day. This size is perfect for my coffee!

I love this thing! I take it everywhere I go, and my water stays nice and icy; my hot cocoa is always steaming! Great job, Hydro Flask!
