HyperDTM is our custom developed line of lightweight diamond grid ripstop nylon. Designed for superior performance and feel compared to standard square grid ripstop, HyperDTM is incredibly strong yet still very soft to the touch. At 1.6 oz, this fabric fills the void between 1.9 oz and 1.1 oz weights when you're looking for something lighter while retaining maximum strength/durability. This calendered version is DOWNPROOF and suitable for use in down gear/projects. 1.6 oz HyperD calendered is best used when you're looking for extra durability over the absolute lowest weight. See HERE for our lighter 1.0 oz HyperD. A premium choice fabric for projects such as top quilts, under quilts, sleeping bags, pillows, and jackets.
