Elite Nano Fly Insulated Water Bottle 500ml Pretty Fly For a Nano Guy You're out riding a bike on a warm, sunny day, and you reach for your water bottle to drink some ice-cold water. The only problem is that your water is now hot enough to make tea with. With the Elite Nano Fly Insulated Water Bottle, you can have constant maintenance of the temperature of cold (or hot) liquids while cycling for up to 4 hours compared with traditional water bottles. The Nano Fly 0-100 can keep your liquids hot or cold for 4 hours with an insulating coating made of Nanogel, which is the world's lightest insulating material because it's made out of 5% solid material and 95% air. It is the lightest commercially available insulated sports bottle, thanks to studies made with different universities and research centers that allowed for helping Elite make such a featherweight, yet sporty and resistant material.
