Great water bottle for a day out
I have many pieces of Hydro Flask now. They are well made, keep water cold all day, and reasonably priced. I got this one because the opening is large enough for ice cubes and still easy to drink out of without spilling. I have the 21 Oz which fits nicely in my car cup holder. It is sleek looking and the little handle on top is handy.

Very satisfied
Excellent water bottle. Very sleek and easy to hold. Keeps water cold. No problem with leaking.What I really love is how easy to clean it is. Bottle can easily be flushed with soap / hot water and I haven’t had any problems with the occasional deep clean in dishwasher.

Great bottle to keep your water cool
Beautiful color with diameter of a plastic water bottle. Its a very high quality bottle that is insulated enough to keep my ice water cold overnight. Have not had any issues with leaks

amazing water bottle
this bottle is great! it’s a perfect size. I really like the handle at the top it’s amazing quality. It tightly seals and doesn’t leak. It keeps the water cold but not for long like it does stay cool but not the same temperature.

Better than most bottles
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
