Here's how it works: the space between the inner and outer flask wall is evacuated, creating a vacuum (well, a partial vacuum anyway...). In order for heat transfer to take place from the outside world into your cold drink, or from your hot drink to the outside world, it needs nearby molecules to excite. If there aren't many molecules nearby, as is the case in a vacuum, the heat's energy can't easily be passed along, so your drink stays close to the temperature it was when you put it into the flask for a really long time. 

Simply stated, vacuums make great thermal insulation!

I LOVE it.

This bottle is amazing. I've wanted it for months, but the Woodland design was out of stock for a while, so I kept waiting and watching, and the minute it came back I bought it. I am so impressed. First of all, it's beautiful. Second, it keeps liquids hot or cold for a long, long time. I took a cold drink to work in it one day, and it stayed cold through lunch (when I finished it). Yesterday, I made hot tea in it in the morning (around 8) and sorta forgot about it. I came back to it around 1pm and it was still very hot. Just for fun, I left it on the table, and when I went to bed, around 9:30pm, it was still warm! I LOVE this insulated flask! Wish I could give it more than 5 stars!

Always Fantastic

Yes. The bottle is wonderful. I was originally wanting the bird designed bottle but that one was sold out at time of purchase. Nevertheless, the forestry bottle is still wonderful :)

Nice flask!

I carry this flask everywhere, it's stylish, keeps my water cool and has not leaked so far! I definitely recommend it!

Seal it up

I love the graphics - which is why I bought it. I do feel like the lid screws on a little wonky at times and I have to really try to keep it straight. It doesn't seem to leak at all but I worry it might if it doesn't screw on just right.

Wonderful bottle, goofy lid

I love this water bottle. One problem was that the lid doesn’t screw on correctly. The company offered to replace it, but I discovered that my hydro flask lid fits it perfectly, so I didn’t bother. I’m a sucker for the nature designs! It keeps my water cold all day (I work outdoors).

Ice. Cold.

1. It has a fantastic texture on the outside that makes it easy to grip. 2. It’s super easy to keep clean because of the wide brim. 3. It keeps my water ice cold all night long. Beautiful product. I’m very impressed. Bought my husband and son one as well; the standard of this company is excellent.
