The Durano Plus has been designed for maximum puncture protection. The SmartGuard protection belt made of elastic rubber may not be quite as thick as the belt of the Marathon Plus. Nevertheless it achieves an unusually high level of protection for a racing tyre. According to Peter Krischio, Schwalbe Product Manager Race: "It is the most puncture-proof racing tyre there is".

At Schwalbe, the abbreviation DD stands for Double Defence. In addition to the RaceGuard protection belt, a layer of snakeskin fabric strengthens, in particular, the shoulder and side wall of the Durano DD ensuring all-round protection combined with minimum additional weight. The snakeskin fabric is new. Now, a monofilament fabric is used that provides even better cut resistance and greater snakebite protection.
