Hydro Flask is keeping it coool :)

Hydro Flask provided our trip with their great water bottles and Revolve water filters! We’ll be able to drink as much water as we want safely and have it stay cold or hot to our liking with these sweet products. The bottles are stainless steel. This means we won’t be drinking any toxic bisphenol-A (BPA) that can sometimes be found leaching into the water in other plastic and aluminum bottles. And the filters will clean the water as we drink!

We of course we'll be needing to stay fully hydrated while on our adventure – we’ll be dealing with lots of physical exertion, exhaustion, and lots and lots of hot sun that will take all we have right out of us. We’ll be able to keep using our 21 oz. Hydro Flask water bottles to avoid going through a ton of plastic water bottles! I’m sure seeing all of the garbage and plastic bottles along the way will make us very glad that we will not be adding to the plastic on Lake Michigan’s shores. 

 A nice science lesson (I told you I was a nerd, you've been warned): Everything that has matter conducts heat, including air. The Hydro Flask has a double wall vacuum built into the bottle. A vacuum is created when the air (that could be conducting heat) is removed from between the two walls of stainless steel. Because there is almost nothing in between the two layers, it is very hard for the temperature of the environment to affect the temperature of the liquid inside the bottle. Cool! Or hot if you want. This insulation will keep our liquids hot for up to 12 hours and cold for up to 24 hours. Hot cocoa? Yes, please. Coffee? Mmmhmm. Icey lemonade? Yeah! Cold beer? Duh. Super cool!
