I feel this flask saves water as it keeps my ice from melting for so long that my water stays cold. I don’t end up continually dumping out warm water. I love my cold water in my Hydro Flask!
I have always used the 32oz. Hydro Flask. It’s the perfect size. It’s not too super heavy and it fits in my car cup holder, but it’s not too small to where I’m filling it up every two seconds. My water is always nice and cold. I also love the straw lid for when I’m working out or working!!
Used in HI while hiking & touring. Kept water cold on hot days in HI. Found a backpack that I easily slipped it and out of - a side pocket. Noted: bigger size so needed a bigger side pocket on the back pack - perfect amount of cold water on a short 3-4 mile hikes.
I bought this bottle about 2 weeks ago, and I have to say that I love it. The only thing I would change is the availability of the sport top lids for the larger/wide mouth bottles. My husband got one for his 21oz bottle, but that was the biggest size it was available for. If those ever become a thing, I will definitely be getting one. When at the gym or in the car, it's very difficult to drink from if there is any extra motion; I'm a huge klutz, so dropping the lid on a dirty gym floor or on the ground and having to replace it makes me wince a bit. Otherwise, the product itself it great and a lot lighter than I expected.
