Tubolito

Tubolito inner tubes are incredibly thin and the lightest inner tubes you can get for your road or mountain bike. They roll up so small that they will easily fit in your back pocket. If you're looking for the lightest possible inner tube for your bike without switching to tubeless, a Tubolito inner tube may be the best solution for you. The weight of a Tubolito tube is less than half of that of an ordinary tube.
