h2o Bottle Connoisseur

  • Familiarity:I gave it as a gift but have feedback to share

This was a graduation gift for my lil' brother and I made the right choice. Check out what he had to say:

"A fantastic water bottle. As a bottle "connoisseur" of sorts, I've tried everything under the sun: Nalgene, Camelback, Clean Kanteen, etc. But this bottle trumps them all. The insulation is so insane that I can leave this bottle in the hot sun all day and there is still ice by 3. The fact that the top needed to be unscrewed every time I wanted a drink irked me a bit, but that problem was solved when I found the top from an old Clean Kanteen bottle fit perfectly into the Hydro Flask. Anyway, this is a useful, durable and overall fantastic water bottle."

So great!

  • Familiarity:I've put it through the wringer

I have purchased almost every Hydroflask item. Their bottles are amazing when it comes to keeping hot liquids hot and cold liquids cold. I have left this bottle in a hot car for a few hours to come back to cold water. Love it!

Best bottle.

Great for long trips. Add a few ice cubes and it's cold for at least a day. Or put in some hot soup. Extremely durable, I drop it all the time. I will invest in a few more down the road.

Keeps hot things HOT!

True to color and size. It has not been used for cold beverages but It really does keep hot liquid hot for up to 12 hours...possibly longer! Even in 0 degree weather. It hasn't been dropped at all, but I will try to update about durability.
