Running out of water in the middle of an adventurous trip is not happening anymore if you have Fontus with you. Just like the name suggests, this is one of the first of its kind self-filling water bottles. It creates water out of light and air and works as an ideal must have for adventurers who are often in need of refilling their water bottles on the go. With Fontus by your side, you will never have to worry about heavy water loads or where to find the next river or gas station to get your water supply. Fontus will set your mind at ease and might even save your life! It will keep you hydrated during your travels and ready for improvisation! You can also clip the Fontus Airo to a backpack and fill your bottle while you are hiking. Allow it to function while you are in motion, or just let it fill while sitting at a campsite. Fontus Airo is a standalone unit whereas the Fontus Ryde is designed for bicycles. A must have for frequent travelers and adventurers out there.
