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

My husband loves hydroflask and he needed one that seals well and travels easy. This worked perfectly. It fits in any cup holder we've encountered and the top hasn't leaks on him so far. It gets daily use so the lid quality seems good. The color is true to the photos. His water stays cold all day and even longer. The handle on the lid means he can comfortably attach it to his backpack too.

I’ve been using Hydroflask since the release. I believe it was 2009 when I purchased my first bottle. Hydroflask has gone through quite a few changes, design wise, changing ownership and adding products. It’s still my go-to hydration bottle. There are probably other bottles on the market equal to Hydroflask but it’s a brand I have found to be reliable. My water stays cold, it doesn’t leak and it can take an occasional drop. The 21oz fit easily into my bag and isn’t to heavy to carry if I’m holding it. I like the matte finish so it isn’t slippery in the hands. The lid quality is good and the handle is easy to grip and hold. A bottle brush fits easily into the bottle for cleaning and the “O” ring on the lid can be removed to scrub it and keep it from getting gross. Overall I highly recommended Hydroflask products.

Perfect gift for Christmas. Perfect size. Bought this as I trust the brand and have bought numerous bottles from hydroflask before. It's easy to use and does not leak. High quality. Dishwasher safe I guess. Let's goo!!

My nephew had a Hydro Flask that he put hot coffee in when he left Arkansas and he said the coffee was still hot when the got to Houston, no less than 7 hours. That convinced me to at least look at them. I got one on sale that was a pink color and have been using it. My friends laughed when they saw the pink flask, but when they saw that it worked so well, they wanted one too, but one of another color. It fits in my cup holder, is easy to clean and small and light enough to fit anywhere .

As someone who’s always on the go, my Hydro Flask has become an essential part of my daily routine. The insulation is no joke—it keeps my water ice-cold during long training sessions and my coffee piping hot when I’m heading to early morning workouts. What really stands out to me is how durable it is; I’ve dropped it more times than I can count, and it barely has a scratch. The wide mouth design makes it easy to fill with ice or clean after a long day, and the sleek design fits perfectly in my gym bag or car cup holder. I also love how it doesn’t sweat, no matter how cold the contents are, which is a huge plus when you’re carrying it around all day. For athletes, travelers, or anyone who values convenience and performance, the Hydro Flask is worth every penny. It’s not just a water bottle—it’s an investment in staying hydrated and fueled no matter where life takes you

I got this for my daughter and she likes it a lot. It's slim, pretty and retains the cold temperature pretty well. Only complaint is that the paint chips off easily...

Perfect water bottle the lid is super leak resistant the color looks just as pictured in description

We love hydro flask. This is probably the 3rd one ive purchased. They keep drink cool for hours. This size fits perfectly in the car cup holder and easy carry.

Nice quality, beautiful bottle. The cab has rubber seals, which doesn’t create noise when using, love it.

I needed to get me one that will fit my daily bag to work. I found this size and til now I am very satisfied. It keeps your drink cool for hours! When I put ice in it in the morning, it will stay there til night. I am a hydroflask user ever since, i left mine back home so I decided to buy one here. Recommended for drinking bottle
