Michelin's Airstop name says it all. Their Airstop tubes use a proprietary butyl rubber that holds pressure longer so you won't have to top off your tires so much. These fine tubes are reinforced at the valve, too.

Schwalbe tubes retain air pressure considerably longer than standard tubes. The quality and purity of the rubber mixture directly affects the quality of the tube.
