Tubolito has released a thermoplastic polyurethane (TPU) inner tube called the X_Tubo City/Tour that comes with a one year warranty against flats. If it punctures within that period you get a free replacement.

“The new, even more resistant material makes punctures impossible during normal use.
“X-Tubo City/Tour is the toughest tube worldwide. It was developed to make punctures a thing of the past and to guarantee worry-free rides in your daily life.”

You just need to register the product within a month of purchase to get a year’s warranty against all flats.
The Tubolito X-Tubo City/Tour is designed for 700C wheels, comes in Presta (130g) and Schrader (139g) versions, and is suitable for tyres from 30mm to 50mm wide – meaning that you could even use it on a lot of road bikes.
