Hydro Flasks are my go to bottles, they keep the water cold all day, I haven't tried hot beverages yet but I'm sure they do just as well. I let this bottle in the sun in a car one afternoon for 3 hours and when I got back to the car there was still ice in it.. yeah, its that good! I have this in 24oz and I was sick of refilling it all of the time so I went with the 40 and I love it. My only complaint on the 40oz is that the lid design isn't very good, mine broke within about a week of standard use. The bottle is still usable though so I can't complain much, I just hope they come up with a better design for the tops on the big bottles!
