Rated 5 out of 5 by from Perfect for AZ GREAT water bottle. I do outdoor sports and activities, even in the hot Arizona summers. I used this for weekend camping and it did a fantastic job of keeping cold water cold. A few friends have smaller Hydro flasks and loved them, so I decided to go for the 64 oz size and have no regrets - I wasn't hiking/backpacking anywhere so having all my hydration in one large container was so convenient. The lid has a flexible, rubber-like handle that seems like it will hold up well. The lid does not leak, and although it takes longer to open than a flip-up cap, I like to take big long gulps from the wide mouth design. Love the "mango" color, too.

Rated 4 out of 5 by from Nice for Beer This thing is great as a growler! Keeps things cold and hot longer and is a great addition to our 32oz bottle by the same company. The bad thing about this is that the paint on the outside gets scuffed and chipped very easily. So easily in fact that every single bottle in the store was marred in some way. However it's only cosmetic so if a few dings don't bother you go with a painted version, if they do opt for the silver one instead.

Rated 5 out of 5 by from Fantastic insulation! I bought this as I need to take quite a bit of water to work (no drinkable fountain and too costly to buy bottles). 7AM, I fill the bottle with 24 1/2 moon ice cubes from my ice maker, add tap water (neither hot nor cold) and by 3PM, there is still ice and ice cold water. I've used it to buy ice and tea at a Casey's and it holds it cold for 6hrs easy. I've even filled it at noon for a road trip, driven 3hrs in 90deg temps, put the Hydro Flask in the room and at 9AM the next day, there is still ice inside.

Rated 5 out of 5 by from Fantastic water bottle with one cautionary note Though large and bulky, this water bottle has some serious insulating abilities! My favorite trick is putting an entire tray of ice cubes in with water that is already refrigerator temperature....this baby (even in black, which I can only imagine greatly increases solar radiation absorption) can sit outside all day and still have those ice cubes 24 hours later. I'd also like to add that I had a 40 oz. one of these, it was in my pack with some valuable field equipment (radio, camera) as well as my own phone, camera, etc., and it was run over by a truck. The bottle sustained enough damage that it was no longer useable, but it was tough enough to get run over by a full size pickup truck and yet maintained enough structural integrity that it absorbed all the damage and none of my more valuable equipment was destroyed! The only cautionary note about this 64 oz. is that when full it is heavy enough to damage itself if it's knocked around a lot - it could definitely get dinged/dented if it fell from any significant height, just because the steel isn't thick enough to not give under it's own weight. Just something to consider, but I would definitely recommend this to anyone. Having 64 oz. of ice cold water ready for you when working out in the 100 degree sun all day is a gift not to be underestimated!

Rated 1 out of 5 by from Lid Cracked within 24 hours of ownership My son purchased this 64 ounce Hydro Flask and within the first day of owner ship, he dropped it on the sidewalk and the lid cracked. Maybe it was just an unlucky fall and if dropped again, it would hold up. For $60 I would expect better durability. Thankfully, we purchased this from REI!!

Rated 5 out of 5 by from Working on the road in Vegas My boyfriend & both work out of our trucks in Vegas. During the summer these bottles work great to keep our water cool while baking at sometimes over 120F. We have the 40oz & 64oz, both are larger, wouldn't necessarily recommend for hiking due to weight.

Will this work with a SteriPen Classic 3?

Asked by: LolaMilano
The prefilter on the SteriPEN Classic 3 will screw on to the top of this bottle. However, the Classic 3 is not designed to treat volumes of water larger than one liter. They recommend splitting larger quantities into portions no larger than a liter in volume and treating separately.
