It is the Super-Abrasion-Resistance Duct.
it's made from a polyurethane/rubber blend, which is also known as TPU (thermoplastic polyurethane). Material is 0.02" thick, except the 2" ID hose is 0.015". Hose has an enclosed bronze-coated steel wire support. It compresses 67% of its length for 2" ID hose; 75% for 3" to 6" ID hose; and 80% for 7" to 10" ID hose. Can be used indoors and out.
Same as pictured here from the DIY and Mr.5
