Hydro Flask Water Bottle - Insulated Stainless Steel - Non Spill, Leakproof in 21 Oz Black

I love my hydro-flask. I got one for each of my family members for vacation. Perfect size and heavy duty.

I like the quality build of this flask. The top fits well and does not leak. There are only two pieces, the flask and the cap, so nothing to fiddle with when cleaning the unit. It does a great job of maintaining the temperature of whatever I put in it. My only reservation is that the flask is a little heavy. I was accustomed to uninsulated plastic containers, with the added pack weight being primarily the fluid in the container. It didn't occur to me that an insulated metal flask might have an empty weight of 0.75 pounds empty, but it does. This may not matter for a casual trip, but for a backpacking excursion it does. I still really like the HydroFlask and plan to use it often. The product is well designed and built.

My son absolutely loves his water bottle. So does my husband. I think I need to buy another soon. 😂 It keeps ice water cold for well over 12 hours. It's easy to clean, takes a beating, and easy to carry because of the handle. I don't think we're going to go to any other brand. We have coffee cups too. The customer service is fast and professional.

The flask does exactly what described. It is 100% leak proof. careful not to fill to top or it will spill when twisting the top. Easy to clean no issues. Comes with twist top which I prefer. Keeps beverages chill or warm your choosing. I would often leave my water bottle in the car and the sun would boil it to extreme heat, but with the flask even in hot day it kept my beverage chill. My only issue was that I picked the 21oz should have gone with a bigger size...that’s on me, great product overall

Everything about it is wonderful. I’ve never had an issue with leakage. Great selection of colors. Perfect size.

I'm definitely a Yeti fan, but this bottle from Hydro Flask does give Yeti some competition. The dings would be I think it might actually get dinged if you drop it...it's not as durable as other reviewers have said. But lightweight is a nice trade off (Yetis can be on the heavy side). The plastic top is nice and it doesn't leak or sweat. The only thing I notice is you kind of have to learn how to properly drink out of it without spilling it on your clothes. Once you figure out that, you are fine. I would definitely buy it again and in different colors. It's a nice product overall.

I have been using the bottle for a few months now and I have had no issues with it. The bottle is very durable and I haven't even gotten a scratch yet. The hydroflask also holds temperature exceptionally well. If I put hot tea in it, it'll hold a at least a warm temperature for 8 hours.

I love this waterbottle, it keeps my water cold all day, I only put a few cubes of ice in each time because I dont like my water to be to cold. But I put in my standard amount of ice, and the it got left in my car all day, and it was a pretty hot day, and It was still cold after being in there for a few hours, it was like half full also which is even more impressive. I love how there is also no sweat or condensation build up on the outside, despite the freezing water inside. The water bottle looks great, and I love the ease of transport, it fits great in a side pocket of my backpack, and it is easy to carry. I love it and would recommend it to anyone.

Muito bom

It is an excellent product. I bought this water bottle about a year ago. Since than its always with me, I mean 24/7. Mostly, I like its big mouth opening design.

Really good well made bottle. Keeps drinks super cool for ages

Pricey but worth it. Would recommend

⭐⭐⭐⭐⭐ Die Hydro Flask 621 ml ist für mich die perfekte Trinkflasche – egal ob im Alltag, beim Sport oder auf Reisen. Sie hält Getränke wirklich stundenlang kalt oder heiß, ohne dass die Temperatur nachlässt. Besonders im Sommer bleibt das Wasser eiskalt, selbst wenn die Flasche stundenlang in der Sonne liegt. Das Material wirkt extrem hochwertig und robust, trotzdem ist die Flasche angenehm leicht zu tragen. Durch die Pulverbeschichtung liegt sie sicher in der Hand und rutscht nicht. Auch nach längerem Gebrauch sieht sie noch fast wie neu aus – keine Kratzer oder Abnutzungen
