Pipistrello is the original Dugast file tread pattern which is made for ripping fast courses as well as sand. We are talking Koksijde sand.
Offered in two (2) casing options: traditional Cotton Casing for the smoothest and most supple ride, and Flying Doctor Casing, which is slightly stiffer, more durable, and about 10 grams lighter. Flying Doctor allows lower pressure without having the feeling that the tire will roll or collapse in the corners.
Both casing options include the Dugast Neoprene sidewall treatment, which means you don't have to seal the sidewalls with Aquasure.
