Rated 5 out of 5 by H2OBoy "Unofficial Test"
OK, I received my 18oz and 32oz Hydro Flask bottles via UPS yesterday and performed my "unofficial" test on the both of them. I own a very expensive and extremely accurate thermometer that is accurate to the degree! I preheated each bottle with 205 degree water for 2-3 minutes, dumped it out and refilled them. The results are:
32oz bottle using standard lid - starting temp 206 degrees - 8 1/2 hours later 150 degrees(still plenty hot for drinking tea, coffee, or your hot drink of choice).
18 oz bottle using flip top lid - starting temperature 203 degrees - 8 1/2 hours later 116 degrees(more luke warm but still fairly impressive in my mind considering the size of the bottle)
Cold tests to be posted later.

I loaded this bottle with ice thinking it was just like previous bottles I have had. What a surprise when I went to empty it at the end of the day to find the bottle was still loaded with ice stuck together in one big clump, big enough that it would not fit through the large mouth opening. I had to let it sit open overnight before it melted enough that I could empty it. I know now that I do not have to load so much ice in it to keep my drink cold for the day. It surpassed all of my expectations. I highly recommend it!

This bottle is not much bigger than a normal 1-liter water bottle. It still fits in the same cup holders as a normal "Nalgene" sized bottle. It keeps things hot. And cold. And it doesn't sweat when you fill it up at a cold stream in warmer weather - a bonus over a typical steel or aluminum bottle.

I filled this thermos w/ ice at 7 am, added some water at 9 am and still had ice remaining at 9 pm. I'm impressed!

Rated 5 out of 5 by Merbear keeps your drink cold all day, sweatproof !
I bought this water bottle for my son's girlfriend in Texas. He told me that her drinks never stay cold all day, especially now that it is really heating up down there. She first of all loved the color and she couldn't believe how cold her drink was and that it stayed that way all day. She said that it is the best water bottle she has ever owned! When I found out how well it worked, I just had to send one down to my son, too.

This water bottle works as promised in keeping liquids cold even when left sitting in a hot car! Also like the fact that it doesn't sweat on the outside. Because of the insulating properties the bottle is a bit larger and heavier than a plastic or single walled stainless 32 oz bottle but the insulating properties are worth it!

I have been using this at work, on my desk. It keeps my drink cold and does not sweat. I wish it had a cover that you could leave on and drink from to help protect against spills. I just have to remember to put the cover back on after I take a drink.
