Whether you'll be spending your day hunting for exotic butterflies or cataloging endless specimens of dung beetles, this insect bottle has got you covered. Fill it with a full 32 ounces of cool water, a fancy chai, (or hey, something stronger, we're not judging) and your drink will be waiting for you at just the right temperature whenever you're ready.

With a textured design for a unique tactile experience, this flask will keep your drink hot or cold until you're ready to enjoy it.

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!

Seriously the most beautiful thing I own! The design is gorgeous, and I love the raised texture. Only small complaint is that one of the bugs chipped off, after only about a week of owning it. The bottle was in my bug and I think it hit against my laptop, causing the design to chip. It's not super noticeable and it was only one of the bugs, but it was still disappointing. Other than that, it is such a gorgeous bottle, great quality, and I love it!

As cool as promised

Got this as a gift for my entomologically inclined girlfriend and it was a hit. The printing on the bottle is done in a really high-quality way -- the images are slightly raised from the surface of the bottle which looks really dope.

My favorite water bottle I have owned so far!

Such a cool design- wish I could easily figure out what kind of insects they are, but I love it nonetheless! I have received lots of compliments and it holds the heat/cold very well.
